Session II: Practical Applications in Industry
Thermal Spray in the Fabrication Process
9:40 AM - 10:10 AM
Dale Moody, Systems Engineer, Plasma Powders and Systems Incorporated
One definition of Fabrication is “To construct by combining or assembling diverse, typically standardized parts.” Typically, a coating, especially one applied using Thermal Spray, is not considered a “Standardized Part”. Therefore, some may question having Thermal Spray included in the normal fabrication process.
This paper addresses this question by reviewing how Thermal Spray has advanced from a highly specialized process to one that is standardized and able to be integrated into a fabrication shop. It summarizes the standard Thermal Spray processes now available to the fabricator and discusses how a fabricator can proceed from total dependence on an outside job-shop for coatings to having in-house thermal spray capability. It also addresses how a fabricator can work with material and equipment suppliers to support a wide range of applications.
High Performance Cermet Coatings for Aerospace and Defense
10:00 AM - 10:20 AM
James S.B. Chew, Business Development, MesoCoat Inc., Vice President-Science and Technology, ATK, Euclid, Ohio
Co Authors: Andrew J. Sherman, President & CEO, Greg Engleman, Chief Technical Officer and Curtis P. Glasgow, General Manger –Thermal Spray, MescoCoat Inc., Euclid, Ohio
PComP™’s are newly developed and demonstrated (ceramic-metal) Cermets developed specifically for an affordable, environmentally friendly hexavalent chromium replacement. The PComP Cermets are fabricated into a hierarchical structure, using a patented process to engineer down to nanoscale. These materials are nano-structured ceramic-metal composites formed with a nanocomposite core and binder coating; which are made using combination of low friction, high wear resistance and excellent corrosion resistant materials. The nanocomposite core provides high wear resistance, low friction and light weight; and the binders provide corrosion resistance, toughness, ductility, resiliency, and improved deposition efficiency. This combination results in a high-toughness, ductile-phased toughened structure of high hardness tiles separated by ductile binder laminates; that offers revolutionary performance and cost breakthroughs. PComP™ is a very promising replacement for hexavalent chrome plating that is widely used in the aerospace sector; and can be applied using conventional thermal spray methods and can be machined using conventional machining methods. This paper presents a variety of cermet coatings applied to steel substrates for various Aerospace and Defense applications, and the resulting properties. These results will then be compared to traditionally processed materials and will conclude with a discussion of the advantages of cermet coatings as a hard chrome replacement.
Thermally Applied Dispersed Oxide Coating System Used in the Mitigation of Corrosion
10:20 AM - 10:40 AM
David Urevich, President, Arc Melt, Bridgeton, MO
Traditionally, protective oxide surface films provided adequate corrosion protection of alloy systems used in most process equipment. Today, however, industry has placed ever increasing demands on these systems to perform in broader, more dynamic, environments. The result has been that these protective oxide films are no longer capable of providing the corrosion protection required. This has spurred a new approach to
corrosion protection through the provision of well bonded, composite cermet coatings. This presentation will discuss a fresh approach to surface treatment; including the manufacturing methodology of raw feedstock materials, application techniques and lab and field test results.
MORNING BREAK - 10:40 AM - 11:00 AM
Thermal Sprayed Active Metallic Coatings Against Environmental Corrosion
11:00 AM - 11:20 AM
Fred van Rodijnen, Global Business Development Manager Arc Portfolio, Sulzer Metco Europe GmbH, Germany
Thermal spray coatings have been used for corrosion protection since their invention in the early 20th century. The power and solar power, to combat their biggest enemy — corrosion. A metallic coating of Zinc, Zinc/Aluminum or Aluminum provides long-lasting active corrosion protection with little or no maintenance or repair for its 20 to 50 years of protective life. Because maintenance and repair needs are eliminated, the carbon foot print from this protective system is very low. Thermal sprayed coatings are environmentally-friendly anti-corrosion systems for green energy providers.
Session III: New Applications and Technologies
New Thermal Spray – A Viable Alternative to Mechanical Devices for Oilwell Casing Centralization
11:20 AM - 11:40 AM
Joe L. Scott, Partner, WearSox LP, Houston, TX
In the development of oil and gas wells, a hole is drilled in the earth and steel casing is inserted into the open hole in successively smaller sizes. After these casing strings are inserted into the hole cement is pumped through the casing and forced to flow up and around the outside of the casing to seal off the formations. In order to keep the casing aligned in the center of the hole a variety of mechanical devices have been employed. These are of four principle types – bowspring, molded on epoxy, rotating and integral
blade stabilizers. The integral blade stabilizers are threaded on each end and are screwed into the string between the joints of casing. These are very expensive and require additional make-up time on the rig floor. The same is true for the rotating type. The epoxy type have proven fragile and often break. The bowspring types slide over the casing and are held in place by collars with set screws. These often slide up the casing during insertion into the well and can bunch up causing a “train wreck”. The new thermal
spray material can be applied directly to the casing wherever needed, applied in the shape of blades, with thicknesses exceeding 3.0 inches, is wear resistant and tough enough to make the trip intact. Work to date has proven the thermal spray technology to be superior in both onshore and deep water offshore wells. This paper describes the development, laboratory testing and field applications of this new technology in thermal spray which will be called TWAS-TWR (Twin Wire Arc Spray – Thick Wear Resistant).
New Applications of Cold Gas-Dynamic Spray (Medium Pressure Cold Spray)
11:40 AM - 12:00 PM
David Wright, President, Accuwright Industries, Inc., Gilbert, AZ
Accuwright Industries, Inc. is a leader in Research & Development and Production applications of Low Pressure and the new Medium Pressure Cold Spray processes. Developing the Cold Spray Process to apply harder and more encompassing materials such as high strength and heat resistive base alloys in a more economical way. Accuwright is developing and pioneering repairs for Stainless Steel, Super Alloy, and Titanium turbine engine parts and worn components with Aerospace and Industrial applications. We propose to describe a few of our developments and specific application successes to share practical potential in Cold Spray process capabilities.
LUNCH (PROVIDED) & EXHIBIT DISPLAY - 12:00 AM - 1:00 PM
Cold Spray: A Solid State Metal Coating Process for Corrosion Protection in a Nuclear Application
1:00 PM – 1:20 PM
Ed Malison, Director of Business Development, CenterLine (Windsor) Limited, Windsor, ON, Canada
Cold spray, or gas dynamic spray, is an established solid state coating process that uses a high-speed gas jet to accelerate powder particles towards a substrate. The kinetic energy is used to plastically deform the particles where they will be consolidated onto the surface to form a very dense, well-adhered coating. The particles never undergo a phase transformation throughout the process which means that the coating raw materials and substrate materials experience minimal thermal affects. We will be presenting an overview of the most recent advances in field-applied cold spray technology that utilizes remote robotic manipulation to apply an aluminum coating to nuclear reactor areas that are extremely difficult to access and where cold spray is, in all probability, the only practical method of coating application.
Intelligent Gun Technology and Its Advantages for Thermal Spray Processing
1:20 PM - 1:40 PM
Steven Ort, Sulzer Metco (US) Inc., Westbury, NY
As the requirements for consistency in thermal coatings become increasingly stringent, the ability to acquire more accurate data at higher speeds becomes increasingly important. To achieve this, process variables must be measured as close to the spray process as possible. This paper introduces a new technology that measures process variables directly inside a thermal spray gun and provides gun-specific data storage features. It explains the advantages of measuring the process variables inside the gun and describes the benefits of having relevant gun data stored on the gun itself.

New Thermal Spray SiA1 Powder Technology Will Advance Rotatable Sputter Target Coatings
1:40 PM - 2:00 PM
Daren Gansert, President, HAI Advanced Material Specialists, Placentia, CA
Rotatable sputtering targets and advanced rotatable magnetrons are used in vacuum coating processes for depositing thin films onto glass. Silicon is widely used for anti-reflection coatings, all-dielectric mirrors, and display glass. The production of SiAl targets by thermal spraying processing is “state of the art”, but there are still many limiting factors that affect the end coated target. The desired functionality of the Sputtering Target can only be achieved by a well designed coating consisting of a finely dispersed, dense, and uniform coating micro structure. The most popular raw powder form is a blended powder composition of Silicon with Aluminum ranging from 0 – 19% by weight. Mechanically blending two dissimilar materials is quite useful but yet can provide many quality issues within the coating which include separation of particles in the plasma flame, over heating (evaporation) of lower melting point metals, e.g. Al, which can increase porosity levels, and inhomogeneous coating composition. One solution to decreasing target coating quality issues is to eliminate using blended powders. This paper will discuss the manufacturing of unique powder formulations which combine both Si and Al into a single particle consisting of the proper chemical composition required for the target. Powder analysis and comparisons between the current blended powders versus single particles will be shown. Thermal sprayed coating cross sections, density and hardness results will be reported. Coating integrity and coating composition will be compared using EDAX and image analysis techniques. Cost comparison(s) will be provided for the raw powders and coated samples; including target efficiency, deposition efficiency and retained Al content remaining in the coated samples.
Session IV: Working with Coatings
Why Thermal Spray Coatings Often Fail
2:00 PM - 2:20 PM
Larry F. Grimenstein, President, National Coating System
Unfortunately many arc sprayed, plasma and even HVOF coatings actually fail rather than coating material wearing out. The cause of these failures is caused by a number of things but they condense to not asking the correct questions. In fact, often there were not any questions even asked. So who should be at fault? This is a joint failure of both the customer and the vendor. Now you are saying, I know that and I always do that therefore it will not fail, unfortunately you are wrong. Do the customer/vendor ask the right questions or even enough of them? This speech is to point out why these failures are overlooked and do not need to happen if the proper materials and applications are done.
AFTERNOON BREAK - 2:20 PM - 2:40 PM
Machining Thermal Spray Coatings
2:40 PM - 3:00 PM
Daniel C. Hayden, President, Hayden Corporation, Managing Partner – Hayden Laser Services, LLC, West Springfield, MA
A practical guide to using and finishing thermal sprayed coatings by tooling and grinding, this presentation covers one of the more challenging aspects of designing for and using thermal sprayed coatings. Machining coatings for use in OEM and repair applications is no more challenging than conventional machining, but some special properties of the coating itself require unconventional tool and wheel selection and gentler infeeding techniques, in order to ensure that the coating will perform as needed. The presentation covers specific techniques, rules of thumb, and standard practices to ensure that coatings will hold up to the tough challenges they face.
Advancements in Abrasive Belt Roll Grinding and Finishing Methods
3:00 PM - 3:20 PM
Nicholas A. Orf, 3M Company – Abrasive Systems Development
Roll grinding and finishing of steel, chrome plated and Thermal sprayed rods, rolls and other cylindrical components has traditionally been accomplished with a variety of bonded abrasive wheel constructions. Recent developments in abrasive belt technology, applied to common Roll grinding equipment has resulted in increased grinder functionality and productivity improvements for Thermal spray providers. This presentation will discuss the abrasive belt technologies applied in roll grinding operations, conversion concepts enabling wheel grinders to run belts, and case studies describing abrasive belt grinding methods which achieve the geometry requirements of ground thermal sprayed components. The benefits of belt grinding and finishing methods including higher productivity and throughput, combined with enhanced roll grinder versatility enabled by the ability to quickly change belts according to the dimensioning, finishing or alloy needs will be tailed.
Thermal Spray Dust Collection Safety as it Pertains to NFPA (National Fire Protection Association) Rules and Regulations
3:20 PM - 3:40 PM
Tony Supine, Technical Director, Camfil FARR Air Pollution Control
As the subject of combustible dust continues to escalate throughout the country, it is important to understand the severity of the risks of handling combustible dusts, know what standards are being defined to deal with them, and who is responsible for following and enforcing them. This presentation offers some insight to all of these points and answers the question; “To whom do these standards apply?”, and “Are any parts of these standards and programs retroactive?” In addition, some small amount of history as to why the standards were developed will be covered along with several common examples of proper explosion protection techniques as defined by the National Fire Protection Association’s guidelines and standards.
