Revealing the excellent corrosion performance of SIMP steel in CO2 at 600 ℃: The role of Si and Mn
Source abstract
Abstract
Compared with T91 and 321, SIMP steel exhibit excellent corrosion resistance in CO 2 at 600 °C. The structure and composition of surface oxide films on the steels were characterized in detail using advanced micro/nano analytical techniques. Different from the typical internal and external spinel oxide layers formed on T91 and 321, a multi-layer oxide film consisting of continuous Cr-rich oxides [Cr 2O 3 and (Cr, Mn) 3O 4] and nearly continuous SiO 2 is external grown on SIMP, acting an excellent protective barrier against oxidation and carbonization. The role of Si, Mn in the corrosion resistance of SIMP steel was discussed.
