    摘要
  • 摘要: 由于材料的磨损性能与其组织关系密切,因此重叠熔敷涂层的制备方法对涂层磨损性能也有着重要影响. 在前期试验基础上制得等离子一层、二层和三层重叠熔敷涂层,采用SEM等观察了重叠熔敷涂层的显微组织和磨损形貌,用半自动显微硬度计进行硬度测试,用磨损试验机测试计算了涂层的摩擦系数,并通过比较3种重叠熔敷涂层的组织和磨损性能,探讨了重叠熔敷工艺对涂层磨损性能的影响,以指导涂层的制备工艺. 结果表明,随着重叠熔敷层数的增加,涂层摩擦系数降低,耐磨性能和载荷特性显著提高.
    Abstract: Due to the close relationship between wear resistance and microstructure of materials, the preparation method of overlapping cladding coating has an important influence on the wear resistance of the coating. Based on previous experimental basis, the plasma overlapping cladding Fe-Cr-Ti-C coatings of one layer, two layer and three layer coatings were prepared. Microstructure of the composite coatings and wear morphology were investigated by means of SEM and micro-hardness of the coatings was tested by semi automatic micro-hardness tester. The coefficients of friction of the coatings were measured and calculated by abrasion tester. By comparing the microstructure and wear resistance of three kinds of overlapping cladding coatings, the impact of overlapping cladding technology on wear properties of the coating was discussed,hoping to provide the guidance for the coating preparation process. Results indicated that the friction coefficient of the coating decreased and wear resistance and load characteristic were improved significantly with the overlapping cladding layers increased.
