摘　　要：分析了水轮机的磨蚀机理,介绍了高速火焰喷涂技术及其在刘家峡水电厂水轮机抗磨蚀方面的应用情况。6年的运行实践证明,高速火焰喷涂技术的喷涂层附着力强,解决了防护层与母材不易结合的问题,提高了水轮机过流部件的抗磨蚀性能。The abrasion mechanism of the hydraulic turbine is analyzed. The HVOF technology and its application in the antiabrasion of the hydraulic turbine in Liujiaxia Hydropower Station is presented. After operation of six years, it shows that the spraying coating in HVOF technology is of perfect adhesion, and it makes the protection coating and the base material easier to adhere. Therefore the performance of the anti-abrasion for the flow passing components of the hydraulic turbine is improved.
