Evolution of corrosion resistance of 310S stainless steel in carbonates melt at 650 ℃
Source abstract
Abstract
Evolution of electrochemical impedance and corrosion products is observed for 600 h on 310S stainless steel in carbonates melt at 650 ℃ under flowing CO 2−2%O 2 gas. Warburg impedance is observed throughout the course of corrosion. Corrosion proceeds with formation of oxides and their dissolution into the melt. The dissolution exposes Ni-rich metallic fragments to the surface as the oxidized macrocrystalline phases, and forms porous inner layer, resulting into the duplex corrosion products. Corrosion is not slowed down until formation of the second layer of corrosion products. The outer layer also does not offer sufficient protection to the inner layer and the substrate, so corrosion is evolving with time.
