Abstract

The high temperature oxidation and Electrochemical corrosion behaviour of several ODS ferritic alloys with different Cr content (12~18 %) were investigated. The oxidation tests were conducted at temperature between 600 °C to 1100 °C in air exposed for up to 500 h. Weight gain was measured after long time exposure to high temperature in air. Electrochemical corrosion behaviour was measured to compare the basic corrosion resistance of different ODS alloys. XRD, SEM-EDS and EPMA were used to characterize the structure, morphology, and composition of the oxide and corrosion scales.
