The Importance Role of WC Coat for Hydraulic Turbine Protection

This article discussed the preserve effect of the WC-HVOF coating to hydraulic turbine based on the research of sand abrasion in hydropower stations on the upstream of Yellow River. At the same time the importance role of WC coat for Hydraulic turbine protection and the great economic benefits from reasonable utilization of WC-HVOF coating are also been discussed in this article, using Sanmenxia hydropower stations as an example. All these have important reference significance for the other similar stations to use WC-HVOF coating to protect the hydraulic turbines.
