| 摘 要： | 为提高TiC/316L不锈钢复合材料的致密度和力学性能,采用温压成型和微波烧结复合方法制备了质量百分数为5%的TiC/316L复合材料.在MM-200型环块磨损试验机上研究了复合材料在干摩擦条件下的摩擦磨损性能,并与传统粉末冶金法制备的复合材料耐磨性能进行了对比研究.结果表明:与传统粉末冶金法相比,在相同的烧结温度下,采用温压成型和微波烧结制备的TiC/316L复合材料虽然内部也存在一些孔隙,但组织比较均匀,烧结比较充分,复合材料的致密度和耐磨性均得以提高.随着温压压制压力的增加,复合材料的相对密度和耐磨性快速增加,但过高的压制压力不利于耐磨性的提高.摩擦磨损试验结果表明在压制压力为400 MPa时,复合材料的耐磨性较好.

| Abstract: | To improve the densification and mechanical properties of TiC/316L stainless steel composites, 316L stainless steel composites with 5% TiC particles were prepared by using warm compaction forming and microwave sintering. The friction and wear behaviors of 316L stainless steel composites were evaluated on a MM-200 wear tester with a block-on-ring configuration under dry sliding using composites prepared by conventional powder metallurgy as a baseline. The results showed that the sample prepared by warm compaction forming and microwave sintering was significantly densified and sintered and had better wear resistance than that of sample prepared by conventional powder metallurgy. The wear resistance of the composites can be increased by increasing the compacting pressure during the process of warm compaction forming. However, high compacting pressure can reduce the wear resistance of the composites. The highest wear resistance of the composites was obtained for composite using a compacting pressure of 400 MPa. |
