摘要:
MAX相因其独特的晶体结构和优良的自润滑性能受到广泛的关注,作为新型固体润滑剂添加到金属基复合材料可获得良好的摩擦磨损性能。采用铝粉、硅粉、Ti3SiC2粉为原材料,通过冷压成型无压烧结法制备了Ti3SiC2增强铝硅基复合材料。研究发现,复合材料的组成物相除Al、Si及外加Ti3SiC2相之外,在烧结的过程中生成了Al2O3和Al4C3。随着硅元素含量的增加,大的圆球形Ti3SiC2逐渐减小。随着硅含量的增加,摩擦系数和磨损失重均呈现先减小后增大的规律。当硅的含量(质量分数)为12.5%,摩擦系数最低,其值低至0.18,磨损失重也达最低。随着硅含量的增加,材料的硬度先增大后趋于平缓,致密度呈线性下降趋势。通过磨损表面SEM分析初步揭示了金属基自润滑的机理,复合材料的磨损机制为磨粒磨损、剥层磨损和氧化磨损并存机制。
