Abstract: The slurry erosion wear is the major problem in the fluid machineries and the hydro turbines where the erodent particles are carried with the fluid and these particles are impacted on the target surface and due to impact volume loss of material takes place. There are several methods are available to control the slurry erosion; however the surface coating using the thermal spraying is mostly used. In the present study, the WC-CO coating is used to reduce the erosion wear and used to improve the life span of the selected material (Gun Metal Bronze). The coating is applied in the substrate material with the help of the high velocity oxy fuel coating (HVOF). The experimentation on the slurry pot tester has been carried out to test the erosion wear. It is observed that the maximum erosion wear is at 15? impact angle and the minimum erosion wear is at 90? impact angle.
