Abstract [en]

Stellite 6 alloy in the form of powder was deposited on a ductile cast iron substrate using a low power pulsed Nd:YAG laser. The effects of process parameters on the resulting microstructure and hardness were studied with emphasis on the single and multi-track deposits. The results revealed that the cladded layers consist of carbides dispersed in a Co-based solid solution matrix with a dendritic structure. Multi-track cladded layers have coarser dendrites compared to those of single-track cladded layer due to a longer exposure time at high temperature and slower cooling rates as more layers were deposited
