Abstract
Coupons of 9Cr–1Mo steel were pre-oxidized in hot air and then partially immersed in molten lead–bismuth-eutectic alloy at 200 °C for various durations. The oxide resistance and capacitance were measured using an AC electrical method. Impedance was found not to correlate with oxide thickness. In connection with other studies on HT-9 and 316L steels, it can be tentatively suggested that oxides on ferritic–martensitic steels may be more conductive than oxides on austenitic steels.
