Abstract

When operating in high silt content flow, the hydraulic turbine is easily destroyed by abrasion and erosion of sediment. Nano WC/Co -High velocity oxygen flame (HVOF) sprayed coating is good to protect hydraulic turbine. Nano WC/Co coating is characterized by its small size of crystal boundary, high bond strength, high hardness, better rupture strength and good corrosion resistance so that the protective coating the coating has high resistance to the high-speed jet. The author described the present conditions of our country´s hydraulic turbines´wear erosion, the characters of nano coating and the application of nano coating on the turbine units anti abrasion in this article.
