Abstract
Granulated glass powder has been plasma sprayed to produce phlogopite (Macor) glass-ceramic coating. Macor glass- ceramic coatings on 316 alloy substrate was prepared by heat treating the resulted glass coated steel. The steel substrate was sand blasted with 35 grid alumina and then bond coated with NiCrAly by plasma spray to provide thermal compatibility between the main coating layer and the substrate. The coating showed chemical stability, and there was no reaction with Fe .The crystallization temperature, thermal expansion coefficient of mica glass-ceramic were 920ºC and 40× 10^−7/◦C, respectively. The microhardness of obtained glass-ceramic coating was 6.8GPa and the friction coefficient was 0.98.
