An Al deposit layer on a SUS 304 stainless steel substrate was formed by electrodepositing Al and alloying it with SUS 304 steel in molten salt. Electrolysis of Al was conducted using a potentiostatic polarization method in an equimolar NaCl-KCl melt containing 3.5mol%AlF<SUB>3</SUB> at 1023K. Deposits formed at −1.3~−1.6V[vs. Ag/Ag<SUP>+</SUP>(0.1)] built up a homogeneous layer, which was adhesive to the SUS 304 substrate. These deposits consisted mainly of Fe aluminides. The thickness of the deposit layer and the aluminum concentration in the deposit layer increased with a decrease in polarization potential. The SUS 304 steel covered by the electrodeposited layer was more resistant than bare SUS 304 steel to high temperature oxidation.
