The rolling wear characteristic of a composite material fabricated from aluminum sludge and aluminum alloy powder by spark plasma sintering was investigated. The rolling wear characteristic of composite material was examined by a rolling wear test and finite element method. The experimental and finite element method results showed that the rolling wear durability of rollers of the same material combination improved, and aluminum sludge played a role in inhibiting crack propagation within the material. On the other hand, the rolling wear durability of rollers of a different material combination deteriorated, and cracks on the contact surface of the composite material tended to occur in comparison to matrix only. Therefore, the rolling wear characteristics of composite materials varied according to the roller material combination.

研究了由铝泥和铝合金粉末组成的放电等离子烧结复合材料的滚动磨损特性。采用滚动磨损试验和有限元方法研究了复合材料的滚动磨损特性。试验和有限元分析结果表明，相同材料组合的轧辊滚动磨损耐久性得到提高，铝泥起到了抑制材料内部裂纹扩展的作用。另一方面，不同材料组合轧辊的滚动磨损耐久性恶化，复合材料的接触表面容易出现裂纹。因此，复合材料的滚动磨损特性随轧辊材料组合的不同而不同。
