Volta potential mapping of the gradient strengthened layer in 20CrMnTi by using SKPFM [PDF]

Journal of Materials Science, 2020
The purpose of this paper is to use SKPFM to characterize the gradient strengthened layer induced by the ultrasonic surface rolling process (USRP). A correlation between the dislocation, residual stresses, and SKPFM-derived Volta potential was obtained using scanning Kelvin probe force microscopy (SKPFM), electron back-scattered diffraction (EBSD ...

Application of micro-electrochemical technologies in atmospheric corrosion of thin electrolyte layer

工程科学学报, 2018
The atmospheric corrosion of a metal under a thin electrolyte layer is caused due to the adsorption of the thin electrolyte layer on metal surfaces. As the electrolyte layer is considerably thin, the application of a traditional three-electrode system is

Initial micro-galvanic corrosion behavior between Mg2Ca and α-Mg via quasi-in situ SEM approach and first-principles calculation

Journal of Magnesium and Alloys, 2023
The initial micro-galvanic corrosion behavior of Mg‒30wt%Ca alloy only containing Mg2Ca and α-Mg was studied by immersion testing in a 0.9% NaCl solution at 37 °C.
