| 摘要: |
| 采用电弧离子镀技术在高速钢和单晶硅上沉积TiAlN和TiAlSiN涂层，利用高温摩擦磨损试验机考察两种涂层在常温、400 ℃和600 ℃下的摩擦磨损行为。通过光学轮廓仪观察涂层磨损后三维形貌和二维磨痕轮廓曲线，利用扫描电子显微镜(SEM)和能谱仪(EDS)分析磨痕、摩擦副的微观形貌以及元素分布，研究Si元素的加入对TiAlN涂层高温摩擦磨损性能的影响。结果表明：TiAlN、TiAlSiN涂层在600 ℃摩擦稳定后的摩擦因数最低，其次是在400 ℃，常温下的摩擦因数最高；TiAlN涂层在常温下摩擦完后已经磨穿失效，而TiAlSiN涂层在600 ℃摩擦完后才失效。粘着磨损和氧化磨损主要存在于TiAlN涂层摩擦过程中，TiAlSiN涂层常温下主要磨损形式为磨粒磨损、粘着磨损以及塑性变形导致的鱼鳞状裂纹，400 ℃下为粘着磨损和氧化磨损，600 ℃下为磨粒磨损、粘着磨损和氧化磨损。 |

| Abstract: |
| TiAlN and TiAlSiN coatings were deposited on high speed steel (HSS) and Si(100) substrates by arc ion plating. The tribological properties of the coatings were investigated using a ballondisc high temperature tribometer (CSM HT1000) at temperatures of RT, 400 ℃, and 600 ℃. The twodimensional (2D) crosssectional profile and threedimensional (3D) profile of the wear tracks on the coatings were obtained by using optical profiler. The effect of Si element on the high temperature friction and wear performance of TiAlN coatings was studied. The surface morphologies and chemical compositions of the wear tracks on the coatings and the wear scars on the wear balls were analyzed using SEM and EDS. The results show that the friction coefficient of the TiAlN or the TiAlSiN coating is the highest at 600 ℃ and the lowest at room temperature, respectively, since the process is stable. The TiAlN coating has worn out after the experiment at room temperature, however, the TiAlSiN coating has not worn out until at 600 ℃. Adhesive wear and oxidation wear mainly exist during the friction test about the TiAlN coating. The wear mechanism of the TiAlSiN coating is the abrasive wear and adhesive wear, with a typical wear feature of the fishlike cracking phenomenon at room temperature. While the wear behaviors of the TiAlSiN coating are characterized by the adhesive wear and oxidation wear at 400 ℃, the abrasive wear, adhesive wear and oxidation wear at 600 ℃. |
