Abstract

In this study, Al–Ti–Co was first used to improve the surface performance of pure Ti. The synthesis of hard composite coating on pure Ti by laser cladding of Al–Ti–Co+TiB₂/Si₃N₄ preplaced powders was investigated in detail. The SEM result indicated that a composite coating with metallurgical joint to the substrate was formed, and the coating can also have major dilution from the substrate. X-ray diffraction result indicated that this composite coating mainly consisted of Ti₃Al, TiB₂, TiB, TiN, Ti₅Si₃ and Co–Ti intermetallics. Compared with pure Ti, the improvement of the microhardness and wear resistance was observed for this composite coating.
