Abstract
Stainless steel powder was coated on mild steel substrate using plasma coating. The porous coating thus obtained was modified using laser irradiation. The oxidation behaviour of the plasma coated as well as laser treated material was studied in air at 1073 K. There was considerable decrease in oxidation rate of mild steel after plasma coating as expected. In addition the oxidation resistance improved significantly after laser treatment. Various laser parameters influence the coating characteristics. Their effect on coating composition and on oxidation rate is discussed.
