Solid Particle Erosion of Duplex Stainless Steel with and Without Nichrome Coating

Premature failure of material is one of the major issues in most of the engineering applications. The material degradation may be due to many reasons. Erosion is one of the major contributors to this issue. In order to extend the life of the material the erosion has to be minimized. Atmospheric Plasma Coating is one of the effective methods of coating to minimize erosion. Studies have established that coating Nichrome can reduce the rate of erosion. In the present study erosion rate was calculated by varying the parameters like angle of impact, velocity and mass flow rate with the help of air-jet erosion test equipment. The erosion rates of coated and uncoated DSS were analyzed. Erosion rate was calculated on the weight loss. On analysis of the data it was established that coatings can reduce the rate of erosion.
