Abstract

A new Ti-based composite coating reinforced with fine and dispersive TiC particles was prepared on Ti-alloy of Ti6Al4V by laser induced reaction of Cr3C2and Ti with respecting the large difference of the thermal stability between Cr3C2and TiC. The results show that laser induced melting is helpful for the formation of this kind of composite coating provided a suitable sets of processing parameters and the ratio of Cr3C2to Ti are selected. The in-situ replacing reaction of Cr3C2with Ti does surely produce a TiC/Ti composite layer containing fairy uniformly distributed fine TiC particles of sub-micrometers and with good bonding to the substrate. The microstructure of the coating can easy be controlled by varying the chemical composition of the powder mixtures pre-placed and also the processing parameters.
