Biphase intermetallic compound wear-resistant alloy was prepared by laser melting deposition technique with bulk silicide Ti-5Si3 as primary phase and with Ti5Si3/NiTi eutectic as substrate. The wear resistance of Ti5Si3/NiTi alloy was tested under dry sliding wearing condition at room temperature and the worn mechanism was discussed. Results show that the Ti5Si3/NiTi alloy has excellent wear resistance and extremely low load-sensitivity under dry sliding wearing conditions, which is attributed to the good match between the toughness and the strength as well as the protection for the alloy from the formation of microstructurally featureless layer with high hardness on the worn surface of the alloy
