| Research Abstract |
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.
