Abstract
In order to investigate the effect of the Fine Particle Peening (FPP) treatment on the oxidation resistance of austenitic stainless steel, an oxidation test was performed at the temperature of 700, 800℃ under atmospheric atmosphere for the FPP treated specimen. The oxidized specimens were analyzed using glow discharge optical emission spectroscopy (GD-OES) and X-ray photoelectron spectroscopy (XPS). As a result, the amount of diffused oxygen into the FPP treated specimen was significantly decreased compared with that of the un-peened one. It was also revealed that protective Cr oxide layer was generated on the FPP treated surface during the oxidation process. These results imply that the FPP treatment is an effective surface treatment for improving atmospheric oxidation resistance of austenitic stainless steel.
