ABSTRACT

Metal matrix composite (MMC) coatings composed of Ni-based alloy and tungsten carbides (WC) were deposited on low carbon steel by powder feeding laser cladding. In the present study, a continuous wave laser (CW) was used. The laser processing parameters were optimized. Sections of such coatings were examined to reveal their morphology and microstructure using scanning electron microscope (SEM) and DTA analyses. The results showed that fully dense clad surfaces of WC- Ni- based alloy with an excellent metallurgical bonding and low dilution were deposited and no melting of WC particles in the Ni- based alloy matrix was observed during the microscopy. Different phases, formed in very small submicron dendrites, precipitates, or eutectic structures, were identified with WC particles of various shapes and sizes in the matrix. Owing to this distribution of hard phases, and WC particles, the Vickers hardness is strongly enhanced and may reach 1400 HV. Finally the quality of the laser cladding is discussed and microstructure observations are presented.
