采用机械合金化(MA)结合放电等离子体烧结技术(SPS)制备了超细晶粒不锈钢和超细晶粒TiC/不锈钢复合材料,研究了316不锈钢原材、超细晶不锈钢和超细晶TiC/不锈钢复合材料的摩擦磨损性能。与316不锈钢原材料相比,超细晶不锈钢和超细晶TiC/不锈钢复合材料的耐磨损性能均明显提高,磨损率分别降低了24.1%和42.3%。316不锈钢原材的磨损主要以粘着磨损为主;超细晶不锈钢的磨损机制主要以磨料磨损为主,粘着磨损为辅;超细晶TiC/不锈钢复合材料的磨损以疲劳磨损为主。
Ultrafine grained stainless steel and ultrafine grained TiC / stainless steel composites were prepared by mechanical alloying (MA) combined with spark plasma sintering (SPS). The effects of 316 stainless steel, ultrafine grained stainless steel and ultrafine grained TiC / Friction and wear properties of stainless steel composites. Compared with 316 stainless steel, the wear resistance of ultrafine-grained stainless steel and ultrafine-grained TiC / stainless steel composites were significantly improved and the wear rates were reduced by 24.1% and 42.3% respectively. The wear of 316 stainless steel is dominated by adhesive wear. The wear mechanism of the ultrafine-grained stainless steel is mainly abrasive wear, while the adhesive wear is minor. The wear of ultrafine-grained TiC / stainless steel composite is dominated by fatigue wear.
