Abstract: In this paper, Al₂O₃/ bronze composite has been prepared via powder metallurgy using conventional technology and equipment. The influence of various sizes and content of Al₂O₃ particles on properties of the composite has been investigated at different sintering temperatures. The technology of chemcial plating has been adopted to pretreat Al₂O₃ particles. The results show that composites fabricated by pressing and sintering two times have fine microstructure, uniformly distributing particles, and better properties than popularly used 6-6-3 bronze bearing material. Chemical plating on Al₂O₃ particles can further improve general properties of the composite.
