TU Professor To Chair Two International Committees

Thursday, August 26, 1999

Edmund Rybicki, chairman of The University of Tulsa mechanical engineering department, has been elected chairman of two international committees involved in developing standards and recommended practices for thermal coatings sprayed on manufactured metal parts to resist wear, high temperatures and corrosion.

Rybicki will chair the American Welding Society International’s C2 Committee on Thermal Spraying and the newly formed American Society of Materials International Subcommittee on Methods to Evaluate Mechanical Properties of Thermal Spray Coatings.

Both societies write recommended practices and standards for thermal spray coatings.

TU researchers have developed ways for evaluating mechanical properties of thermal spray coatings. Some of these evaluation methods have been presented to the two committees as potential recommended practices for the industry.

TU’s mechanical engineering department has conducted research for 10 years on thermal spray coatings. Results of the research have been used by NASA and by companies such as Boeing, Ford and Volvo.

The TU research has led to four awards for papers in international journals and conferences.

Rybicki, mechanical engineering professor John R. Shadley and TU undergraduate and graduate students have shown that residual stresses in thermal spray coatings can enhance or diminish the fatigue life and the ability of the coatings to stick to the metal under mechanical loadings.
