摘要
对采用ＰＶＤ、ＣＶＤ和ＰＣＶＤ表面涂覆处理的六角切边模和内六角冲头的生产使用情况和使用寿命进行了比较，其中ＰＣＶＤ涂层模具寿命比未涂层模具提高一倍以上。提出了改善涂层与基体间结合强度的途径和方法，并对冲击载荷下涂层模具的失效机理进行了分析。
The service lives of shear dies and punches treated by PVD,CVD and PCVD are compared.The rule and method of improving the interface strength between coating and base material are presented.The failure mechanism of coated dies under impact loads is studied.
