Electrochemical behaviour and passive film characteristics of an ultra-thin 316L foil with a thickness 20 μm in 3.5 wt.% NaCl solution were investigated using multiple techniques, focusing on the effect microstructure, applied potential, pH solution. The microstructure contains mainly fine grains (∼4 μm) high-angle boundaries preferential orientation (220), no MnS inclusion was detected. electrochemical measurements show significantly higher breakdown potential lower current density for than...
Abstract The reformation and characterisation of the passive film formed on ultra-thin 316 L after hydrogen charging is investigated by combining EBSD, TMDS, XRD, Synchrotron-based XPS, electrochemical experiments. results show that foil reforms a 12 h release in NaCl solution. reformed half thickness as-received dominated Cr oxides/hydroxides. lattice extension caused residual accelerates migration to form 2 O 3 ; while diffusible occupies cation vacancies high defect density for within h.
The formation and evolution of the corrosion scales on super 13Cr stainless steel (SS) surface after exposure in a formate completion fluid with presence various aggressive substances was investigated. results indicate that Fe 3 O 4 covered SS as inner layer accompanied outer scattered FeS. rate below 0.07 mm/year 120 h at 180°C under N 2 environments; such sulfide CO promoted proceeding anodic dissolution early period, ingress progressively increased general to 1.7 mm/year.
