Abstract

Wear resistant Ti₂Ni₃Si/Ni₃Ti multiphase intermetallic coatings with a microstructure consisting of Ti₂Ni ₃Si primary dendrites and interdendritic Ti₂Ni ₃Si/Ni₃Ti eutectic were fabricated on a substrate of 0.2% C plain carbon steel by a laser cladding process with Ti-Ni-Si alloy powders. The Ti₂Ni₃Si/Ni₃Ti coatings have excellent wear resistance and a low coefficient of friction under metallic dry sliding wear test conditions with hardened 0.45% C carbon steel as the silide-mating counterpart. The excellent tribological properties of the coating are attributed to the high hardness, strong covalent-dominant atomic bonds of the ternary metal silicide Ti₂Ni₃Si and to the high yield strength and strong yield anomaly of the intermetallic compound Ni₃Ti.
