目的 研究CrAlSiN涂层分别与304不锈钢、TC4钛合金、Al2O3陶瓷和GCr15钢四种不同材料配副时的摩擦学特性。方法 采用阴极电弧离子镀技术在M35高速钢上制备了CrAlSiN涂层，采用扫描电镜（SEM）、显微硬度计、划痕仪、球-盘式摩擦磨损试验仪和3D轮廓仪分别测试了涂层的结构和性能。结果 CrAlSiN涂层与304不锈钢、TC4钛合金和GCr15钢配副时的磨损形式为粘着磨损和磨粒磨损，其中与亲和性高的304不锈钢、TC4钛合金粘着磨损严重。CrAlSiN涂层与不锈钢对磨时，摩擦系数最高，达到0.71；与GCr15钢对磨时，摩擦系数最低，但摩擦系数波动大；与钛合金对磨时，摩擦系数介于两者之间。CrAlSiN涂层与亲和性较差的Al2O3陶瓷之间的磨损形式为磨粒磨损，随着磨损的进行，摩擦系数逐渐降低。结论 CrAlSiN涂层与亲和性较高的材料对磨时，磨损形式为粘着磨损和磨粒磨损，与亲和性较差的Al2O3对磨时为磨粒磨损。

The work aims to study tribological properties of CrAlSiN coatings sliding against 304 stainless steel, TC4 titanium alloy, GC15 steel and Al2O3 ceramic, respectively. CrAlSiN coatings were fabricated on M35 high speed steel by adopting cathodic arc ion plating technology. Structure and properties of the coatings were tested with scanning electron microscope (SEM), microhardness tester, scratch tester, ball-on-disc friction-wear tester and 3D profiler. Wear forms of CrAlSiN coatings sliding against 304 stainless steel, TC4 titanium alloy and GCr15 steel were adhesive wear and abrasive wear. Serious adhesive wear was observed on the coatings sliding against high affinity materials such as 304 stainless steel and TC4 titanium alloy. The friction coefficient was the highest (0.71) when the CrAlSiN coatings slid against stainless steel; the friction coefficient was the lowest but fluctuated greatly when the CrAlSiN coatings slid against GCr15 steel; the friction coefficient fell in between when the CrAlSiN coatings slid against TC4 titanium alloy. Wear form of the CrAlSiN coatings sliding against poor affinity Al2O3 ceramic was abrasive wear, and the friction coefficient decreased gradually as wear continued. Adhesive wear and abrasive wear occur when CrAlSiN coatings slide against high affinity materials, and abrasive wear occurs when the coatings slide against poor affinity Al2O3 ceramic.
