To Check the Feasibility of Cr2O3 Coating on Boiler Steel Tubes Simulated Coal Fired Boiler Conditions to Prevent the Erosion

ABSTRACT: Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Plasmas spraying is one of the thermal spraying techniques known for providing hard, wear resistant and dense microstructured coatings. This paper shows the results of chromium coating on on ss-304 and ss-310 by plasma spraying technique
