| Abstract: | In the present paper, a continuous wave 2kW Nd-YAG laser was used to synthesize TiN/Ti metal matrix composite on the surface of Ti6Al4V alloy. The microstructure and the wear resistance of the synthesized SMMC were investigated. The synthesized surface TiN/Ti MMC had a pronounced gradient microstructure through the melt depth. Good metallurgical bonding between the reinforcing phase TiN of the SMMC and the Ti6Al4V matrix was observed. The hardness and wear resistance under block-on-ring dry sliding wear conditions of the synthesized TiN/Ti SMMC were markedly enhanced. |
