| 摘 要： | 为了进一步拓展金刚石涂层刀具的产业化应用,提升金刚石涂层刀具的结合力性能,本文开展了细晶粒钨钴类硬质合金的化学预处理研究,考察了三步法预处理工艺对不同晶粒度基体形貌和成分的影响,实现了金刚石涂层与基体的高结合强度。利用扫描电子显微镜和EDS能谱仪对预处理后基体的表面形貌和钴含量以及涂层形貌进行分析,采用拉曼光谱、X 射线衍射光谱对涂层物相结构进行分析表征,并利用固体颗粒冲刷评价金刚石涂层的抗冲刷性能。结果表明:酸处理对Co的去除起着重要作用,WC晶粒越小所需酸处理的时间越长,碱处理对WC的刻蚀能力表现出先增大后减小的趋势,在3min时达到最大Co暴露量。由此分别确定了WC-6%Co(0.2,0.4,1.0 μm)基体三步法最佳工艺,三步法预处理后的基体均获得均匀致密,晶粒取向为(111)面,抗冲刷性能优异,膜基结合性能好的金刚石涂层。
