As the construction of a number of high head hydropower stations in our country, the performance requirements of wear resistant material for concrete member and over-flow surface are more and more strict due to the large flow sediment concentration, the characteristics of high velocity and large flow. By summarizing the domestic and foreign research situations in the field of material erosion wear, GNF paint coating was selected in this paper. The grinding experiment was carried out using the ring anti-wear testing machine to study the resistance of the coating and concrete specimen and wear-resisting performance. The results showed that, the effect of coating was the best grinding when the sediment particle size ranged from 0.02 mm to 0.04 mm, also , the indoor curing condition among different curing conditions was the best fit for the best coating.
