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 properties. 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 investigated. 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.

原位复合材料具有界面清洁、粒径合适以及增强体与基体之间良好的界面结合等明显优势，在选择具有优异摩擦学性能的材料方面起着主导作用。在本研究中，制备了原位 TiC 增强锌铝合金复合材料，并研究了施加载荷和研磨距离对这些复合材料的高应力磨粒磨损响应的影响。还测试了基体合金和常规使用的青铜色的高应力磨料磨损性能。据观察，将 TiC 增强材料的含量从 5%（重量）增加到 10%（重量）会提高锌铝基复合材料的耐磨性。
