High-resolution Kelvin probe microscopy in corrosion science: Scanning Kelvin probe force microscopy (SKPFM) versus classical scanning Kelvin probe (SKP)

Electrochimica Acta, 2007
With the introduction of a Kelvin probe mode to atomic force microscopy, the so called scanning Kelvin probe force microscopy (SKPFM), the Kelvin probe technique finds application in a steadily increasing number of different fields, from corrosion science to microelectronics and biosciences.

The Influence of Microstructure on the Corrosion Behaviour of AZ91D Studied by Scanning Kelvin Probe Force Microscopy and Scanning Kelvin Probe

open access: yesCorrosion Science, 2006
beta-Mg17Al12, eta-Al8Mn5 and an alpha-magnesium phase have been synthesized from pure components by controlled solidification procedures. These phases have been studied using different electrochemical techniques including the scanning Kelvin probe (SKP).

Light Metal Alloys Local Reactivity, from AFM Based Scanning Kelvin Probe Force Microscopy (AFM-SKPFM) to Scanning Electrochemical Nanocapillary (SEN)

ECS Meeting Abstracts, 2022
Materials surface heterogeneities obviously plays a crucial role in reactivity issues and generate various types of detrimental localized corrosion attacks. In corrosion science, a first question to be addressed is how these various materials microstructure affect oxidation / passivation and localized corrosion initiation mechanisms.

Hydrogen Diffusion and Trapping in a Low Copper 7xxx Aluminium Alloy Investigated by Scanning Kelvin Probe Force Microscopy [PDF]

open access: yesMaterials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2017
The susceptibility to hydrogen embrittlement (HE) of the 7046 aluminium alloy (AA 7046) was investigated. Samples of AA 7046 corresponding to different ageing temperature/time couples were hydrogenated by cathodic charging in a H2SO4 solution.

Improving the Relative Calculations of Volta Potential Differences Acquired from Scanning Kelvin Probe Force Microscopy (SKPFM) By Comparing Inert Standards to First-Principle Calculations

ECS Meeting Abstracts, 2018
Metal corrosion is an electrochemical process typically controlled by features such as grain boundaries, defects, coating/metal interfaces, composition, and local chemical environments. Advances in characterization tools have progressed the means to resolve these features with hopes of better understanding corrosion initiation and progression ...

Corrosion behavior of a duplex stainless steel under cyclic loading: a scanning Kelvin probe force microscopy (SKPFM) based microscopic study

Journal of Applied Electrochemistry, 2012
Corrosion fatigue behavior of the duplex stainless steel AISI 2205 was studied by the scanning Kelvin probe force microscopy (SKPFM) in the ambient temperature and pressure condition (25 °C, one standard atmospheric pressure). Surface-polished AISI 2205 samples were subject to a cyclic tensile stress while immersed in a 0.5 M NaCl solution.
