摘要
用铸造的方法制备了原位自生复合碳化物[(Ti,W,Cr,V,Nb)C]增强钢基复合材料,并对该复合材料的磨粒磨损性能及磨损机理进行了研究。结果表明,采用该方法制备的钢基自生复合材料中,自生碳化物颗粒细小、圆整、且分布均匀,碳化物颗粒增强相体积分数达到42.8%;原位自生钢基复合材料的耐磨性能优良。在磨粒磨损条件下,其磨损机制主要是显微切削、颗粒脱落和脆性剥落;稀土和合金元素能够提高原位自生钢基复合材料的耐磨性能。
The abrasive attrition and wear properties of in-situ carbide reinforced steel matrix composites(Fe(Ti,W,Cr,V,Nb)Cp)were measured.The results show that in-situ carbide particle exhibits fine and round morphology and uniform distribution in the in-situ steel matrix composites,reaching up to 42.8%(volume fraction),which results in the composites possessing excellent wear resistance.In the condition of abrasive attrition,the wear loss is mainly caused by micro-cutting,particle shattered and brittle micro-peeling.The wear resistance of in-situ steel matrix composites can be greatly improved with increasing Re and alloying elements addition.
