摘要
在室温条件下,选用三体磨粒磨损试验机,石英砂磨料,研究增强相WC颗粒直径对WCp增强钢基表层复合材料磨损性能的影响,以20%Cr高铬铸铁作为标样,计算相对耐磨性值。结果表明,WCp增强钢基表层复合材料相对于20%Cr高铬铸铁的相对耐磨性,随其增强相WC颗粒直径的变小而降低,当增强相WC颗粒直径大于150μm时,相对耐磨性值达到5左右,而当增强相WC颗粒直径小于100μm时,相对耐磨性值降低到1左右,即与20%Cr高铬铸铁的抗磨粒磨损性能相接近。
Under three-body abrasive wear conditions, quartz sand as abrasives, the relative wear resistance of the WC（p） reinforced steel matrix composites, mating material is white iron 20 % Cr, was investigated at room temperature. The results show that the relative wear resistance decreases with decrease of the WC particle size. When the particle size is above 150 μm, the relative wear resistance is about 5, Whereas the particle size is less than 100 μm, the relative wear resistance decreases to 1 more or less, which is close to that of white iron 20%Cr.
