Microscopic aspects of electrochemical delamination: an SKPFM study

Electrochimica Acta, 2003
Abstract While the basic mechanisms of anodic and cathodic delamination, i.e. the de-adhesion of polymer coatings from the metal substrate, are already well understood [Industrial Adhesion Problems, Orbital Press, Oxford (1985); Polymeric Materials for Corrosion Control, American Chemical Society, Washington (1986); Corrosion Control by Organic ...

Evaluation of Initial Corrosion Phenomenon of Magnesium Alloys by SKPFM

Materials Science Forum, 2011
Magnesium (Mg) has the lowest standard electrode potential in structural materials, and then it easily corroded for that property contacting with other metals. The corrosion resistance of Mg alloys was generally investigated by conducting saltwater immersion test, salt spray test, and electrochemical corrosion test.

Local potential measurements with the SKPFM on aluminium alloys

Electrochimica Acta, 2004
Nowadays several measuring techniques, like SVET, SRET and Kelvin probe, exist to study local potential differences on alloys surfaces. One very sensitive technique with good spatial resolution is scanning Kelvin probe force microscopy. This technique enables direct measurement of the local Volta potential differences resulting from very complicated ...

Characterization of chromate conversion coatings on zinc using XPS and SKPFM

Surface and Coatings Technology, 2005
Abstract Chromate conversion coatings (CCCs) on zinc have been studied using SEM, AES, XPS and scanning Kelvin probe force microscopy (SKPFM), aiming at understanding the protective mechanism of the CCCs. The SEM images show that the size of microcracks increases with the dipping times in chromate bath, and no crack has been observed when the dipping
