Abstract

The high temperature oxidation resistance behavior of a AISI430 ferritic stainless steel with a FeCrAISi coating was investigated at 900°C in air by the continuous measurement of the weight gain. The micro-structural characterization was performed by scanning electron microscopy (SEM) and the composition was determined by energy dispersive spectroscopy (EDS). The FeCrAISi coating was found to possess good resistant to oxidation at 900°C in air. The results confirmed that the good oxidation resistance of the FeCrAISi coating was attributed to formation the thin a-Al₂O₃ phases on the coatings´ surface and at the substrate/coating interface.
