| 摘 要： | 本文主要研究刀具材料，试验环境对金刚石涂层刀片耐磨性的影响，探讨刀片的耐磨性和耐腐蚀性，试验发现金刚石涂层提高了刀片耐磨性２０％－４５％，金刚石漠膜均有不同程序的肃落，限制了涂层刀片的耐磨性，试验表明屑末溶液和醋酸，盐酸混合溶液不腐蚀金铡石薄膜，但腐蚀基体材料，金刚石薄膜磨耗机理是“磨损变形－裂纹－磨屑形成”，高速钢刀片以磨料磨损为主，腐蚀损为辅，粘结剂（钴元素）丧失是硬质合金刀片磨损的根本原因，一旦残余粘结力不足以抵抗磨控所产生的剪切力，碳化钨颗粒就会因疲劳而脱落。

| Abstract: | The study was to investigate the effects of tool materials and experimental surroundings on diamondcoated tool wear. It was expressed that diamond-coated tools decreased tool wear with 25～45 percent, but diamond membrane was to some extent peeled off, hindering diamond-coated tool from improving tool life with much higher extent. It was realized from the worn edge of tools that both chip solution and the mixed solution of hydrochloric acid and acetic acid did not corrode the diamond membrane, however etched the matrix composition. It might be convinced that the wear of diamond membrane resulted from "plastic deformation-crackle-particle peeling". The abrasive mechanism was mainly responsible for the tool wear of high speed steel in additional to the corrosion mechanism. The binder of cemented tungsten carbides was etched by chemical corrosion. In case the residual forces were not enough to hold the carbides, the carbides would disappear for abrading fatigue. |
