| Authors | |
| Abstract | This paper describes the pioneering work of various researchers in the field of slurry erosion behaviour of uncoated and coated materials in various industrial applications. The present study is focused on the slurry erosion behaviour of ash slurry disposal system of thermal power plants. The key components such as impeller and casing of ash slurry disposal pumps in thermal power plants experience this phenomenon of wear. Tribological parameters such as solid particle concentration, impact velocity of erodent on the target surface, impact angle, erodent particle size and shape, hardness of the striking particles and target material, etc. are responsible for slurry erosion. The research results show that the influence of tribological parameters on the slurry erosion is found to be significant and need to be evaluated and analyzed properly. The slurry erosion can be minimized by proper selection of materials and/or by providing the suitable protective coating on the material which can enhance the surface properties. |
