摘　　要：综述了水力机械过流部件抗磨蚀材料及其防护技术的发展历程 ;概括了抗磨蚀材料的组织结构及机械性能与磨蚀的关系 ;讨论了抗磨蚀材料从铸铁、青铜、碳钢到合金钢的发展历程 ;分析了表面抗磨技术的应用现状 ,指出表面覆层处理是解决磨蚀的有效方法 ,其关键是抗磨蚀材料的设计与选择。This paper reviews the developing course of the erosion-wear resistant materials and the protective technology of hydraulic equipment, discusses the relationship between the material microstructure and the mechanical property. Through analyzing the present situation of the application of the materials, it is obtained that the surface coating treatment is the effective method of resolving erosion-wear and the key to resisting erosion-wear is the design and selection of the material. Finally, the paper presents the prediction to and looks forward to the erosion-wear resistant materials and the protective techniques
