... to increased corrosiveness, unlike shear stress. There was localized corrosion in most of the evaluated test conditions, confirming the importance of using laboratory techniques that allow such analysis. Localized as well as generalized corrosion kinetics decrease over time, confirming that laboratory tests...

... to assess these probes for providing early warning of potential structural failure due to localized corrosion under complex buried pipeline conditions. Electrode array-based corrosion probes were successfully deployed in selected locations across Victoria Australia. The probes performed as expected...

... ABSTRACT Localized corrosion (pitting and crevice) is one of the main causes of damage of stainless steels in industrial applications. In order to study the corrosion behavior of stainless steel in the presence of chlorides, the Pedeferri’s diagram can be used. The diagram, originally...

ISO15156-3/NACE MR0175 3(1) is generally used as one of the standards in the material selection with SSC and SCC resistance in H 2 S...

... ABSTRACT A previously developed modeling framework has been extended to predict the general and localized corrosion of various corrosion resistant alloys (CRAs), including alloys 2507, 2535, 28, 29, S13Cr, S15Cr, and S17Cr in complex aqueous systems relevant to oil and gas production...

... ABSTRACT Nickel-Aluminum Bronze (NAB) and Copper-Nickel alloys (CuNi) are commonly used in seawater environments due to their strength combined with a good corrosion resistance and a high resistance to biofouling. However, localized corrosion failures have been reported and are often...

... 2 S and CO 2 partial pressures. The susceptibility of CRAs to SCC is believed to be related to the ability to sustain localized corrosion in the environment of interest. 3-4 Work has been done to demonstrate that SCC of CRAs occurs when the corrosion potential of the materials in the environment...
