Abstract The mechanical and tribological characteristics of the VN/AlCrN multilayered coating films are investigated for cutting tools by using the arc ion plating (AIP) method with a rectilinear magnetic filtering system. The VN coating film forms vanadium oxide VxO1–x that has low friction coefficient on a surface above 500°C, whereas AlCrN coatings exhibit higher hot hardness and oxidation resistance. Therefore, the VN/AlCrN multilayer coatings are expected to demonstrate both superior lubricity and heat resistance, whose characteristics depend mostly on the combination of VN and AlCrN films. Moreover, some lower cutting force, tool wear, and tool flank temperature are obtained at high speed end milling of a prehardened stainless steel, as expected.

VN/AlCrN-多层PVD涂层刀具的润滑性和耐热性铣削特性

摘要 采用电弧离子镀（AIP）方法和直线磁过滤系统研究了刀具用VN/AlCrN多层镀膜的机械和摩擦学特性。VN 涂层膜在高于 500°C 的表面上形成具有低摩擦系数的氧化钒 VxO1-x，而 AlCrN 涂层具有更高的热硬度和抗氧化性。因此，VN/AlCrN 多层涂层有望表现出优异的润滑性和耐热性，其特性主要取决于 VN 和 AlCrN 薄膜的组合。此外，正如预期的那样，在对预硬不锈钢进行高速端铣时，可以获得较低的切削力、刀具磨损和刀具后刀面温度。
