摘要
研究了激光重熔前后ＷＣ／Ｎｉ６０Ａ等离子喷涂层的组织结构及性能特点，试验结果表明，激光重熔层中除Ｎｉ基合金及ＷＣ等固有的碳、硼化物外，还出现了Ｎｉ３Ｆｅ等新的弥散硬质点，重熔层的硬度和耐磨性较等离子喷涂层有明显提高。
The microstructure and properties of plasma-sprayed coat of WC/Ni60A with laser remelting, as well as without laser remelting,is dealed with.The results show that in the remelted coat,besides Ni-alloy and the fixed carbides and borides such as WC,new hard phases appear,for example, Ni 3Fe and α-W 2C. The hardness and wearing resistance of laser remelting coat has been greatly improved than that of plasma-sprayed coat.
