Abstract
In this study, silicon carbide (SiC) composite coating layer was produced by Plasma Transferred Arc (PTA) welding methods. Microstructure, hardness, and tribological performance were investigated on the composite coating layers. The results showed that the silicon carbide powders are completely dissolved during the PTA cladding process and the microstructures consisted of dendrites and interdendritic eutectic structure. The SiC composite coatings have significantly increased the hardness due to the eutectic structures. The PTA cladding processes improved the wear resistance 3.8-fold compared to that of the substrate. [ABSTRACT FROM AUTHOR]
