将Ti、Fe和TiC粉末进行低温球磨,并结合放电等离子烧结制备Ti-Fe-xTiC(x=0,3,6,9,质量分数％)复合材料.结果表明:该复合材料中含有β-Ti、β-Ti-Fe、η-Ti4Fe2O0.4以及TiC颗粒.显微组织随着TiC添加量的增加而显著细化.粘着磨损是Ti-Fe-xTiC复合材料的主要磨损机制.随着TiC添加量的增加,摩擦因数(COF)减小,硬度增大.其中,由于Ti-Fe-6TiC复合材料中TiC含量较高,TiC颗粒尺寸小,组织细化程度高,因此,具有最佳的耐磨性能,磨损率仅有1.869×10-5 mm3/(N·m),同时,摩擦因数为0.64.由此可见,TiC颗粒增强Ti-Fe基复合材料在耐磨材料领域具有潜在的应用价值.
Ti-Fe-xTiC (x=0, 3, 6, 9, wt.％) composites were fabricated through low temperature ball milling of Ti, Fe and TiC powders, followed by spark plasma sintering. The results show that β-Ti, β-Ti-Fe, η-Ti4Fe2O0.4 and TiC particles can be found in the composites. The microstructure can be obviously refined with increasing the content of TiC particles. The coefficient of friction (COF) decreases and the hardness increases with increasing the content of TiC particles. The adhesive wear is the dominant wear mechanism of all the Ti-Fe-xTiC composites. The Ti-Fe-6TiC composite shows the best wear resistance, owing to the small size and high content of TiC particle as well as relatively fine microstructure. The wear rate of the Ti-Fe-6TiC composite is as low as 1.869×10-5 mm3/(N·m) and the COF is only 0.64. Therefore, TiC particle reinforced Ti-Fe based composites may be utilized as potential wear resistant materials.
