Microstructure evaluation of CO-222/SiC coating produced by the plasma spraying method

A composite coating containing 10 wt-% of SiC and 90 wt-% CO-222 super alloy was coated with atmospheric plasma spray at two different currents on the surface of the 304 stainless steel. The aim of this research is to address the microstructure and phase formation during the plasma spray of Co-222/SiC composite coatings. The phase analysis, microstructure, surface morphology and microhardness of Co-222/SiC feedstock powder and the coating were...
