An experimental investigation into strain and stress

Pan, T. Corrosion behavior of a duplex stainless steel under cyclic loading:a scanning Kelvin probe force microscopy (SKPFM) based microscopic study. J Appl Electrochem 2012; 42:1049 1056. Google Scholar Crossref ISI Assessment of steel corrosion and deadhesion of epoxy Scanning Kelvin Probe (SKP) was used to determine the mechanism(s) of corrosion and paint de-adhesion. This technique is sensitive to the metal-polymer interface and gives a quick assessment of cathodic delamination or anodic undermining.

Characterization of corrosion of X65 pipeline steel under

Corrosion of X65 pipeline steel under a disbonded coating was studied by scanning Kelvin probe measurements. Three types of specimen were designed and prepared to investigate the effects of immersion time, oxygen concentration and wetdry cycle on Kelvin potential profile and thus corrosion behavior of the steel. Kelvin potential measured on intact area is shifted negatively with time Corrosion and Materials Degradation An Open Access The scanning Kelvin probe (SKP) was applied to automotive martensitic steel grade MS1500 in order to detect local reactivity of the surface after hydrogen uptake and tensile deformation. Hydrogen and stress distribution in microstructures can be characterized by SKP indirectly measuring the potential drop in the surface oxide.

Pressure on Metastable Pitting Corrosion of X70

Corrosion test results also indicated that pitting initiation and propagation are accelerated by hydrostatic pressure. Result validity was veried by evaluating metastable pitting to predict pitting corrosion resistance.
