Room N230a
The American Welding Society and The International Thermal Spray Association are organizing the first Thermal Spray and Coatings Conference, to be held in conjunction with the 2009 FABTECH INTERNATIONAL & AWS WELDING SHOW Including METALFORM. The program is intended to introduce the process and its uses to new potential users with morning and afternoon sessions focusing on actual applications and new developments in thermal spray technology.

An Overview of Thermal Spray Processes & Applications
9:00 AM – 9:30 AM
Richard Thorpe, Praxair Surface Technologies
Thermal spray processes have developed through the years from simple, unsophisticated devices used to spray a few pretty basic applications with common chemical compositions to ever more complex systems capable of applying highly-developed coatings with intricate matrixes. Beginning with simple wire and powder flame guns using a flammable gas and oxygen spraying low velocity flames, the technology has evolved to the advanced air plasma spray (APS) and high velocity – oxygen fuel (HVOF) systems capable of spraying at much higher temperatures and velocities with alloys and composite materials used in the aerospace industry. Thermal spray processes and their applications have come out of the black art era and have now moved into an enlightened era of science and practicality.
Practical Understanding of Materials for Thermal Spray Applications
9:30 AM – 10:00 AM
Mitch Dorfman, M. Oechsle and C. Dambra, Sulzer Metco
Thermal spray technology has been used successfully for many years in various wear resistant applications. The technical success of an application is based not only on the correct thermal spray process and parameters, but on a clear understanding of the wear mechanism(s) associated with the application and the proper material selection. Based on this fundamental understanding, powders can be selected to meet specific application needs. This presentation will discuss various WC-Co(Cr) and WC-Co(Cr) self-fluxing alloy powders that are presently in the market place. Important characteristics related to powders for wear applications are: 1) primary carbide grain size, 2) overall powder particle size, 3) manufacturing process, 4) matrix chemistry, and 5) powder density. Low and high angle erosion, adhesive wear, abrasive wear and fretting are just a few of the types of wear mechanisms reviewed in order to help grow applications in industrial markets such as agricultural, paper and pulp, hydroelectric, and hard chrome alternatives.
Comparison of Hardcoating Processes
10:00 AM – 10:25 AM
Daniel Hayden, Hayden Corp.
Originally authored for the oil and gas industry, this presentation discusses the physical application and performance differences between common atmospheric (non-vacuum or inert environment) hardcoating techniques, including thermal spray, spray and fuse, traditional welding, and laser/PTA applied overlays. The discussion focuses on basic economic factors influencing the selection of one technology over another and attempts to highlight the pros and cons of each technology. It is intended to present each hard-coating method as a suitable choice for a select set of coating needs, rather than promoting one technology as superior to all others. Specific factors addressed are application cost, physical effects of the coating process to the substrate, durability of the overlay, and accuracy of deposition. For the purposes of this new thermal spray conference, additional discussion of individual atmospheric thermal spray processes is also included.
