Study on Two-body Abrasive Wear Properties of Cast WC/Ni-based Alloy Composites

Cast WC/Ni-based alloy composites were made by vacuum hot-pressing liquid sintering technology. The effect of different size and volume fraction of cast WC on the two-body abrasive wear properties of composites of Ni-baesd alloy reinforced with cast WC were studied and compared with high chromium cast iron (Cr28).The results show with the increasing of size and volume fraction of cast WC, the resistant-wear of cast WC/Ni-based alloy composites was higher, and much better than chromium cast iron.
