Sodium dodecylbenzene sulfonate film absorbed on magnesium alloy surface: An electrochemical, SKPFM, and molecular dynamics study

Journal of Molecular Liquids, 2022
International audience ; Sodium dodecylbenzene sulfonate (SDBS) was used as an environmentally friendly corrosion inhibitor to alleviate the corrosion of magnesium alloys in 3.5 wt% NaCl solution. In this study, the corrosion inhibition impact of the SDBS inhibitor on AZ31 alloy surface was investigated by electrochemical, scanning Kelvin probe force ...

Role of Hydrogen in Intergranular Corrosion of 2024 Aluminum Alloy: an SKPFM Study

CORROSION 2017, 2017
Abstract This work aims at determining the influence of hydrogen on the corrosion damage of 2024 aluminum alloy (AA 2024), a commonly used alloy in aeronautics. A powerful way to study hydrogen embrittlement at a local scale is by Scanning Kelvin Probe Force Microscopy (SKPFM).

ICP-MS, SKPFM, XPS, and Microcapillary Investigation of the Local Corrosion Mechanisms of WC–Co Hardmetal

Journal of The Electrochemical Society, 2008
WC-Co hardmetal exhibits high corrosion susceptibility in aqueous solutions, related to complex microscale reaction mechanisms. This paper presents developed methods to characterize the local distribution of surface reactions difficult to assess by conventional electrochemical methods. Laterally resolved electrochemical potential distributions measured

Optimization of Metallographic Sample Preparation for AFM/SKPFM Based Phase Distinction of Complex and Dual Phase High Strength Steels

Practical Metallography, 2021
Abstract For the comprehensive investigation of advanced high strength steel grades, like complex and dual phase steels, Atomic Force Microscopy (AFM) and Scanning Kelvin Probe Force Microscopy (SKPFM) have proven to be useful tools, especially for analysis of hydrogen permeability of the individual steel phases.

The mechanism of hydrogen-induced pitting corrosion in duplex stainless steel studied by SKPFM

Corrosion Science, 2012
Abstract The influence of the hydrogen charging on the pitting corrosion in duplex stainless steel was investigated by the scanning Kelvin probe PROBE force microscopy. The Volta potential maps of the hydrogen charged sample revealed that some low potential areas emerged at the ferrite/austenite boundaries or inside the ferrite phases, which may be ...

Relations between sample preparation and SKPFM Volta potential maps on an EN AW-6005 aluminium alloy

Corrosion Science, 2005
Quantitative measurements of the chemical composition and the local Volta potential contrast on metal surfaces can be performed with sub-micrometer resolution using a combination of scanning electron microscopy (SEM) and scanning kelvin probe force microscopy (SKPFM).

SKPFM and SEM study of the deposition mechanism of Zr/Ti based pre-treatment on AA6016 aluminum alloy

Surface and Coatings Technology, 2007
Abstract The formation of Zr/Ti based pre-treatments is strongly affected by the microstructure of 6xxx alloys for application in the automotive industry. AA6016 was pre-treated using a fluotitanate/fluozirconate acid based model solution at room temperature.

Corrosion Phenomenon Evaluation of Mg Alloys using Surface Potential Difference Measured by SKPFM

2016
Magnesium is easy to be corroded because it has small standard electrode potential (SEP). In magnesium alloys, the corrosion resistance of dispersoids hasn’t yet evaluated quantitatively as the SEP of dispersoids wasn’t almost investigated. This study surveyed the surface potential difference (SPD) between α-Mg in AZ91D magnesium alloy and the ...

Study of the Corrosion Mechanism and Corrosion Inhibition of 2024 Aluminum Alloy by SKPFM Technique

Materials Science Forum, 2008
Aluminum alloys have found many applications in different branches of industry. In spite of the valuable properties, there is a significant drawback because of the strong corrosion susceptibility, especially in chloride-containing medium. The present work is focused on study of the 2024 aluminum alloy corrosion mechanism on early stages using Scanning ...
