摘　　要：利用UMT-2高温摩擦磨损试验机、结合MFT-4000型多功能表面性能试验仪对比研究不同含Al量TiAlN涂层PVD涂层力学性能和加工汽轮机不锈钢材料的摩擦性能。结果表明,Al含量高的AlTiN涂层的抗剪和抗压强度均和整体力学性能比Al含量低的TiAlN涂层好;在摩擦过程中,TiAlN涂层不平稳,AlTiN摩擦过程平稳,摩擦系数低;切削试验表明Al含量高的AlTiN涂层更适于加工汽轮机不锈钢材料。The mechanical properties and friction behavior of Ti-Al-N coating with different Al content for turbine blade material are studied by UMT- 2 high- temperature friction and wear test machine,combined with MFT- 4000 multifunctional surface properties tester. The experimental results show that the shear and compressive strength,the overall mechanical performance of AlTiN coating which has more Al content are better than TiAlN which has less Al content; In the friction process,the TiAlN coating is not stable,but the AlTiN coating is stable,and the friction coefficient of AlTiN is lower; The cutting experiments show that the AlTiN coating with more Al is more suitable for the processing of stainless steel materials.
