Abstract—In this study two commonly used steels in boiler plants, i.e. (SAE-213) T-22 and SA516 (Grade- 70) were coated with different thermal spray processes namely HVOF and cold spray. The coating powder used was made up of NiCrTiCRe powder. The performance of the coated as well as uncoated material was investigated using a pin-on-disc machine [Model: Wear and Friction Monitor Tester TR-20], supplied by M/S DUCOM, Bangalore (INDIA) wear using different loads.
