AbstractIn this study, silicon carbide (SiC) composite coating layer was produced with 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. SiC composite coatings have significantly increased the hardness due to the eutectic structures. PTA cladding processes improved the wear resistance 3.8-fold compared to the substrate.
