摘　　要：采用磁过滤电弧离子镀技术在高速钢基体上沉积TiAlN涂层。研究了N_2分压对TiAlN涂层的相结构、化学成分、力学性能、沉积速率、表面粗糙度、结合强度以及摩擦磨损性能的影响。结果表明,N_2分压的变化对涂层的结构与性能影响显著。随着N_2分压的增加,TiAlN涂层呈现(111)择优取向,其硬度最高可达34 GPa。涂层的沉积速率和表面粗糙度随着N_2分压的增大而逐渐降低。此外,由于大颗粒的去除使得涂层表面质量得到提升,所制备的TiAlN涂层均具有较低的摩擦系数(0.15~0.33),并且呈现良好的抗磨损性能,其最低磨损率为8.8×10^(-7)mm^3/(N·m)。TiAlN coatings were deposited on high-speed steel substrate by filtered arc ion plating technic.Effect of nitrogen partial pressure on phase structure,chemical composition,mechanical properties,deposition rate,surface roughness,adhesion and tribological properties of TiAlN coatings is studied.The results reveal that there is a strong influence of nitrogen partial pressure on coating structure and properties.By varying the nitrogen partial pressure,the maximum hardness of 34 GPa is achieved for the TiAlN coating with a strong（111） preferred orientation.The deposition rate and surface roughness of the coatings decrease gradually with increasing the nitrogen partial pressure.Due to the improved surface quality by eliminating the most of macro-particles,all the TiAlN coatings show relatively low coefficient of friction,which varies in the range of 0.150.33.The coatings also possess good wear resistance,showing the lowest wear rate of 8.8×10-7mm3/（N·m）.
