水轮机叶片在运行过程中，由于受到高速水流的冲击、气蚀作用，以及水流中夹杂的泥沙等介质的摩擦和切削作用，造成叶片磨损、磨蚀破坏，形成局部腐蚀，从而影响水轮机的出力和运行效率，因此，对水轮机叶片进行表面处理是提高叶片抗磨蚀能力的有效方法之一。从水轮机叶片磨蚀特征、磨蚀机理以及其影响因素等角度来说明水轮机叶片磨蚀破坏的本质，为水轮机叶片选材及耐磨蚀工艺的研究提供依据。同时，还阐述了水轮机叶片耐磨抗蚀金属涂层的主要制备技术，并对未来表面处理技术提出展望。

Water turbine blade in the process of operation were easy to make blade wear, abrasion damage and formation of local corrosion,due to the impact of the high-speed flow,cavitation effect, friction and sand in the stream media and cutting action,thus results to affect the turbine output and efficiency. Therefore,the surface treatment of turbine blade is one of the effective methods to improve the abrasion resistance of the blade. This article explain the essence of the turbine blade abrasion from the turbine blade abrasion characteristics,abrasion mechanism and its influencing factors,and it provides the basis for the research of turbine blade material and abrasion resistant technology. At the same time,also expounds the turbine blade abrasion resistance corrosion main preparation technology of metal coating,and surface treatment technology is put forward outlook in the future.
