| Abstract: |
| The light beam cladding of Ni-based +WC wear-resistant alloys was accomplished with the equipment and auxiliary fixture developed by ourselves. The analysis on the microstructure and hardness of the cladding layer showed that a good metallurgical bonding with the substrate metal was obtained. The macrohardness and microhardness of this layer were increased effectively compared with that of the base metal. It was predicted that the light beam cladding layer of Ni-based alloys on the 1045 steel surface will possess superior wear-resistant properties. |
