Effect of in situ TiC reinforcement and applied load on the high-stress abrasive wear behaviour of zinc-aluminum alloy

In-situ composites with clear advantages of a clean interface, adequate particle size, and good interfacial bonding between the reinforcement and matrix play a lead role in choosing materials with superior tribological prop-erties. In this study, in situ TiC reinforced Zinc Aluminum alloy composites were prepared, and the effect of applied load and abrading distance on the high-stress abrasive wear response of these composites was investi-gated. Matrix alloy and conventionally used Gunmetal were also tested for high-stress abrasive wear properties. It was observed that increasing the TiC reinforcement content from 5 wt % to 10 wt % results in improved wear resistance in the Zinc aluminum-based composite. The 10 wt % TiC reinforced composite shows superior wear behaviour among all samples and proves to be a suitable replacement of gunmetal in bearing applications.
