Abstract

An intermetallic Fe-Al coating was successfully produced on 316LN austenite stainless steel by slurry Aluminizing. The coating greatly enhanced the corrosion resistance of substrate in LBE (lead-bismuth eutectic) containing low (10⁻⁷ wt%) and high (1.8 ×10⁻³ wt%) oxygen concentrations at 550 ℃ and the coating was mostly intact after 1500 h exposure test. The high corrosion resistance results from the formation of a uniform layer of alumina oxide on the coating which can be achieved when the dissolved oxygen is above 10⁻¹⁸ wt%. This FeAl coating maybe a promising option for protecting structure material in the fourth LBE-cooled fast reactor.
