英文摘要 | A gradient nano- and submicron-structured surface layer of SIMP steel was produced by means of shot peening (SP). Compared with the original samples, corrosion experiments at 550 degrees C for various durations (120 h-1218 h) in liquid LBE showed that the oxidation resistance of the SP samples is significantly improved by shot peening, owing to the enhanced diffusivity of Cr by the large number of grain boundaries and dislocations introduced by shot peening, making it easier to form enhanced Cr-rich oxides. The magnetite layer of the SP samples has higher compactness, giving it better resistance to exfoliation than that of CG samples. |
