Abstract

In this study, a highly wear and corrosion resistance coating was fabricated on 304 stainless steel. Herein, air plasma spray coating of Cr2O3 was deposited on 304SS which was subsequently treated with laser at different travel speeds these were: 25 mm/min, 50 mm/min and 100 mm/min, respectively. The morphology of coatings was studied by using scanning electron microscopy. It revealed that ultrafine grain structure is found as travel speed is increased, the as-solidified microstructure got more and more refined. Wear test demonstrated that with increase in laser t speed, the wear rate increaased. Furthermore, wear rate of laser treated coating at travel speed of 25 mm/min exhibits very comparable result at 8 N and 16 N.
