Article Preview

Wear resistant NiMo/Mo2Ni3Si intermetallic composite with a microstructure of ternary metal silicide Mo2Ni3Si primary dendritic, the long strip-like NiMo intermetallic phase, and a small amount of Ni/NiMo eutectics structure were designed and fabricated. Wear resistance of NiMo/Mo2Ni3Si composites were evaluated under different load at room-temperature dry-sliding wear test conditions. Results indicate that NiMo/Mo2Ni3Si composites have excellent wear resistance and sluggish wear-load dependence. The dominant wear mechanisms of NiMo/Mo2Ni3Si composites are soft abrasion and slightly superficial oxidative wear.
