| 摘 要： | 对不锈钢表面激光涂覆Ni基纳米WC／Co复合涂层的耐磨性进行了研究。结果表明，与热喷涂及喷焊Ni基WC／Co涂层相比，激光涂覆Ni基纳米WC／Co复合涂层的相对耐磨性明显较高。在选定的试验条件下，激光涂覆层的相对磨损体积分别为热喷涂及喷焊层的6．91％及15．46％，其原因是激光快速涂覆工艺及纳米WC／Co综合作用的结果。

| Abstract: | The wear resistance of Ni-based nano-WC/Co coating on the surface of stainless steel by laser clad was researched.The results show that the relative wear resistance of the coating is obviously better than that of hot-sprayed and spray welding coating.The relative wear volume of the laser clad coating under certain measuring conditions is 6.91% of the hot-spray coating or 15.46% of the spray welding coating respectively,effect of the laser fast cladding and due to the comprehensive the nano-WC/Co powder. |

| Keywords: | laser cladding nickel based nanometer WC/Co composite coatings wear resistance. |
