摘要

Wear resistant γ/Mo₂Ni₃Si metal silicide "in situ" composite consisting of Mo₂Ni₃Si primary phase and lamellar γ/Mo₂Ni₃Si eutectics was fabricated by the laser melting process. The γ/Mo₂Ni₃Si composite has an excellent wear resistance under metallic dry sliding wear test conditions mating with hardened 1.0% C-1.5% Cr bearing steel. The excellent tribological properties are attributed to the high hardness of Mo₂Ni₃Si and the toughening effect of the ductile γ solid solution. Wear of the γ/Mo₂Ni₃Si composite is governed by the micro-cracking and spalling of the dendritic Mo₂Ni₃Si primary phase and the preferential wear of the interdendritic γ/Mo₂Ni₃Si eutectics.
