三种材料多弧离子镀TiN涂层性能比较

The properties comparisin of TiN coating of multi-arc ion plating on three materials

硬质TiN薄膜广泛用作高速钢刀具的耐磨层,较少用于其他钢种。本文选择W6Mo5Cr4V2、3Cr2W8V和GCr15三种材料用多弧离子设备沉积TiN涂层,测定了涂层的表面硬度、涂层与基体的结合力、TiN涂层的结构及过渡层硬度分布。试验结果证明:只有选择在沉积温度下保持高的硬度及含有较多合金元素尤其是V元素的基体材料。

TiN coatings deposited onto high speed steel(HHS)by physical vapor deposition have successfully been used in metal cutting applications for a number of years.But its use to other materials is studied fewly.The present paper sudied hardnes and adhesion of three materials.The show that if want to acquere good property of TiN coating we must select material that has high hardness on the temperature when TiN coating deposited and that contains more alloy elements especially V.
