| 摘 要： | 研究了1Cr17Ni4马氏体型不锈钢表面等离子体喷涂FeCrA1Y、NiCrAlY2O3和NiCrAlY金属涂层的组织结构和小位移滑动的摩擦磨损特性。采用拉伸方法进一步分析了各涂层的结合强度、结果表明，在该等离子体喷涂工艺下，3种涂层摩擦系数相当，均明显低于ICr17Ni4不锈钢基材的值；Ni基涂层耐磨性能有所提高，其中NiCrAlY金属涂耐磨性能最好．但FeCrAlY涂层耐磨性能不及基体材料。3种涂层的磨损机制主要为磨粒在磨损中的塑性变形机制和疲劳磨损机制。

| Abstract: | FeCrAlY,NiCrAlY2O3,NiCrAlY coatings on 1Cr17Ni4 stainless steel were prepared by plasma spray. Friction and wear characteristics of these coatings were studied under dry sliding of small dis- tance. The strength of these coatings was measured by tensile method. The friction coefficients of these coat- ings are almost the same, and much smaller than that of 1Cr17Ni4 matrix. The wear resistance of Ni-based coatings had been improved, and wear resistance of NiCrAlY coating is the best. Wear resistance of FeCrAlY coating is worse than that of 1Cr17Ni4 matrix. The predominant wear mechanism of the coatings appeared to the plastic deformation of abrasive wear and the fatigue delamination. |
