Corrosion at Sulphide Inclusions in Stainless Steel
نویسنده
چکیده
Auger analysis was performed using a high resolution scanning auger electron microscope and auger electron spectroscopy. Elemental auger contour maps for corroded sulphide inclusions in stainless steel were presented. It was found that the copper enriched-manganese sulphide inclusions were uniformly corroded, which might be due to CU2S deposition on the surface of corroding inclusions. In contrast, manganese sulphide inclusions containing less copper were non-uniformly attacked, resulting in the formation of deep microcrevices at their edges.

A Conceptual Model for the Interaction between Carbon Content and Manganese Sulphide Inclusions in the Short-Term Seawater Corrosion of Low Carbon Steel
The critical role of manganese sulphide (MnS) inclusions for the initiation of the short-term growth of pitting or localized corrosion of low carbon steels has long been recognized. Classical results show that pitting probability and pitting severity increases with increased sulphide concentration for low carbon steels as a result of magnesium sulphides acting as local cathodes for initiating p...
متن کاملAtomic-scale decoration for improving the pitting corrosion resistance of austenitic stainless steels
Stainless steels are susceptible to the localized pitting corrosion that leads to a huge loss to our society. Studies in the past decades confirmed that the pitting events generally originate from the local dissolution in MnS inclusions which are more or less ubiquitous in stainless steels. Although a recent study indicated that endogenous MnCr2O4 nano-octahedra within the MnS medium give rise ...
متن کاملMechanism of copper action on pitting phenomena observed on stainless steels in chloride media
The influence of the addition of copper on the resistance to pitting corrosion of stainless steels has been investigated using different experimental techniques––current transient analysis, polarization curves in acidic media, pitting and repassivation potential measurements, XPS and SEM observations––so that pit initiation, propagation and repassivation could be analysed separately. Copper add...

9 In some sour reservoirs and tertiary oil recovery blocks, SO42in solution can cause the corrosion 10 and corrosion fatigue of the sucker rods. In this paper, the corrosion behaviors of super-strength 11 sucker rod FG20 (16Mn2SiCrMoVTiA) steel in the well fluid are investigated by electrochemical 12 measurements, and electron probe micro-analyzer (EPMA) analysis. The results show that FG20 ste...

Sensitivity analysis methods were used in conjunction with a mathematical model for corrosion pit initiation in the vicinity of MnS inclusions in stainless steel to investigate the relationship between physicochemical parameters and the potential and concentration distributions. The finite difference method with central differences was used to calculate sensitivities. The mathematical model of ...
