Passive Films Formed on Fe- and Ni-Based Alloys in an Alkaline Medium: An Insight Into Complementarities Between Electrochemical Techniques and Near-Field Microscopies (AFM/SKPFM)

Applied Sciences (Switzerland), 2023
This study investigates the natural passivation process of two types of stainless steels (AISI 316 and AISI 304) and a nickel-based alloy (Inconel 600) as a function of immersion time in an alkaline medium.

Using SKPFM to Determine the Influence of Deformation-Induced Dislocations on the Volta Potential of Copper

Metals, 2021
The variation rule of the Volta potential on deformed copper surfaces with the dislocation density is determined in this study by using electron back-scattered diffraction (EBSD) in conjunction with scanning Kelvin probe force microscopy (SKPFM).

Analysis of Hydrogen Distribution and Diffusion in Pre-Strained SUS316L through Scanning Kelvin Probe Force Microscopy and Thermal Desorption Spectroscopy

Energies, 2023
Austenitic stainless steels (γ-SS) play an important role in the storage of high-pressure hydrogen. However, hydrogen embrittlement (HE) can significantly degrade the mechanical properties of γ-SS.

Effects of laser welding on the microstructure evolution and corrosion resistance of a novel nitrogen-containing austenitic stainless steel QN2109

Journal of Materials Research and Technology, 2023
After laser welding, the corrosion resistance and microstructure of a newly developed austenitic stainless steel, QN2109, were investigated. A negligible heat-affected zone was found and the segregation of Cr, Mo, Mn, Ni, and N was revealed by EPMA.
