| Abstract:The performance, structure and material requirements of AlSn40-steel bimetal bearing plating are introduced. The self-developed new AlSn40-steel bimetal bearing plating is detected in detail with regard to its physicochemical indexes, and compared with the one made by a foreign company. The results show that the chemical component, mechanical performance, and metallographic structure of home-made AlSn40-steel bimetal bearing plating basically meet with the technical requirements. However, it still has the problems of loose structure and binding strength, hence improvement solutions are proposed. |
