Abstract

Chromium-based coatings on steel, cathodically electroplated from Cr(VI) and Cr(III) electrolytes, were studied to compare their corrosion resistance following application of uniaxial strain. An organic overcoat (PVB) was applied to strained samples and an in-situ scanning Kelvin probe technique was...
