| 摘要: |
| 研究综合采用了电子枪等离子增强、非平衡磁控溅射和多弧离子镀3种物理气相沉积（PVD）技术，在高速钢麻花钻上沉积TiAlN单层涂层。对涂层的硬度、涂层与基体的结合强度、微观形貌进行了测试及分析，并将TiAlN涂层高速钢麻花钻对1Cr18Ni9Ti不锈钢进行干态钻削试验。结果表明，在高速钢麻花钻基体上所制备的TiAlN涂层具有良好的力学性能，可以使高速钢麻花钻的使用寿命提高4倍以上。 |

| Abstract: |
| TiAlN coating has been deposited on HSS twist drill by the Physical vapor deposition (PVD) technology which combined with plasma enhance, multiple arc ion plating and unbalanced magnetron sputtering. Morphology, hardness, elastic modulus and adhesion strengths of the coating has been evaluated, respectively. In addition, dry drilling test has been carried out in 1Cr18Ni9Ti stainless steel. The investigation showed that TiAlN coating has a good mechanical property, the TiAlN coated HSS twist drill demonstrated over four times improvement in tool life. |
