| 摘 要： | 刀具磨损是机械加工刀具常见的失效形式，高速钢刀具是最常用的切削刀具，本研究以高速钢为基体材料，以M—W—P为基质合金，通过适当的前处理技术在高速钢刀具表面制作Ni—W—P合金镀层。扫描电镜照片显示Ni—W—P合金镀层呈胞状结构，镀层成份分析表明，M、W、P的质量分数分别为81．14％、4．17％和3．15％，原子分数分别为63．26％、1．04％和4．65％，该镀层为低磷含量镀层。X射线衍射图谱分析，该镀层为晶体结构。经300℃热处理后，显微硬度以及耐磨性提高，显微硬度是基体材料的2倍，耐磨性是基体材料的4倍。通过该工艺得到的M—W—P合金镀层表面光亮，涂层均匀，结合力良好。
