Dry Sliding Wear Performance Studies of WC–12Co Deposited on AISI 420 Steel Through Microwave Energy

The WC–12Co-based clad powder was deposited on the AISI 420 substrate using the microwave energy. The dry sliding action of the WC–12Co-based microwave coating on the substrate AISI 420 was studied using a pin-on-disk testing equipment. The dry sliding wear study was carried out as per Taguchi OA L9. Speed, sliding distance, and load parameters were considered at three various levels. The more wear rate was observed on the unclad surface than the clad surface. Enhanced sliding resistance of the microwave cladding is due to the uniform distribution of carbides. Unclad surface experiences the removal of binder and degradation of carbide grain, while clad surface suffers plastic deformation and undergoes microscale wear.
