在这项研究中，我们开发了一个基本的测试方法，再现实际冲压加工过程中模具表面涂层的滑动损伤。为了模拟实际生产过程，使用了由SKD 11制成的模具，在其上通过PVD、CVD或TRD涂覆TiC、TiN、CrN或VC。用该方法对涂层的滑动损伤进行了定量评价，结果与X射线衍射技术和表面粗糙度测量结果吻合较好。在镀锌的空白钢板的情况下，发现表面损伤是由锌粘附到涂覆的模具上引起的。通过TRD，VC涂层获得了优异的抗滑动损伤性能。
In this study, we developed a basic test method of reproducing the slide damage of surface coating layers on dies during actual press working. To simulate actual production processes, dies made of SKD11 on which TiC, TiN, CrN, or VC was coated by PVD, CVD or TRD were used. The sliding damage of the coatings was quantitatively evaluated by this new method, and results showed good agreement with the results of the X-ray diffraction technique and surface roughness measurement. In the case of galvanized blank steel sheets, it was found that the surface damage was caused by the adhesion of zinc onto the coated die. Excellent resistance against the sliding damage was obtained for the VC coating layer by TRD.
