Abstract

This paper demonstrates the feasibility of generating a thin clad coating of WC-12%Co, TiN and TiAlN on SS304 base material by using the pulsed Nd-YAG laser. In the first case, the hard metal carbide (WC) gets dissolved in the molten liquid metal (Co), acting as binder thus producing the desired matrix. In the second case TiN based composite coating was created with and without the addition of Al-powder. In the post processing, a precision grinder was employed to smoothen the top surface. Microhardness mapping was performed at various points across the surface. The results show the average microhardness value of 1910 HV for WC-12%Co coating, whereas the microhardness of the coating deposited with TiN is lower (1035 HV) than that of using Al-mixed powder (1264 HV)..
