Abstract: The research and application situation of Al-based sliding bearing alloys is reviewed in terms of type, microstructure and properties. The methods including structure refinement, alloying element addition, surface modification and dual-scale structure controlling for improving the properties of Al-based sliding bearing alloys are described. It is proposed that the new Al-based sliding bearing alloy can be designed and prepared by referring to the new preparation process and microstructure design of high-performance alloys and combining the manufacture techniques of Al-based alloy bearing shell strip.
