Meet Dr. George T. Bayer - Coatings Group Manager 

In his current position as Manager of the Coatings Group at Matco Associates, where he began working in 2001, Dr. Bayer is responsible for managing and performing a variety of analyses and characterization projects, primarily directed toward metallic, organic, and ceramic coating systems for a wide range of applications. Since joining Matco, Dr. Bayer has been involved in over 150 coatings-related projects. Dr. Bayer’s degrees include B.S. and M.S. degrees in Chemistry (1980, 1983) from the University of Pittsburgh. Dr. Bayer’s graduate research in chemistry focused on rare earth-transition metal hydrides. He also obtained M.S. degrees in Energy Resources (1983) and Metallurgical Engineering (1992) from the University of Pittsburgh, where his graduate research in metallurgical engineering focused on oxidation-resistant ceramic coatings for carbon-carbon composites. Most recently, Dr. Bayer obtained his Ph.D. in Engineering (1999) from Kennedy-Western University’s School and Engineering and Computer Science, where his doctoral research focused on the development of a chromium-silicon co-diffusion coating system for high-temperature and aqueous corrosion applications.

.

Early in his career Dr. Bayer worked at Energetics, Inc., Columbia, Maryland (1986-1988), and at Princeton Economic Research, Inc., Silver Spring, Maryland (1988-1989), providing technology assessment, proposal review, and R&D program management support to diverse U. S. Department of Energy Office of Conservation and Renewable Energy R&D projects, primarily materials- and chemical-related. Dr. Bayer worked from 1993 to 2001 as Technical Manager at Alon Surface Technologies, Inc., Leechburg, Pennsylvania. At Alon, he held primary responsibility for the development of four new commercial diffusion and thermal spray coating products and processes, as well as support to production, quality, and technical marketing efforts. Dr. Bayer’s industrial research efforts at Alon have resulted in 5 U.S. patents granted. He has also worked from 1990 to 2001 as an independent contractor and consultant, providing technical services in a variety of areas. These areas include SBIR proposal review, technology assessments, thermo-chemical modeling and process development, patent application preparation and other technical writing, and consulting on development, testing and application of diffusion and thermal spray coatings.

Dr. Bayer has authored or co-authored 25 technical papers and book chapters, 2 ASTM specifications, and holds 5 U.S. patents, as discussed above.  He is a member of the ASM International, the American Chemical Society, and the Engineers’ Society of Western Pennsylvania.
