Kelvin Probe Force Microscopy for High-Resolution Imaging of Hydrogen in Steel and Aluminum Alloys (original) (raw)

Understanding hydrogen interactions in metal alloys is crucial for hydrogen storage applications, as atomic hydrogen can lead to hydrogen embrittlement causing stress and premature cracking. This research aims to utilize Kelvin Probe Force Microscopy (KPFM) to visualize hydrogen segregation at nanometer scales in high strength steel and aluminum alloys. The experiments include characterizing microstructures of various alloys and employing electrochemical charging methods to assess hydrogen concentration profiles associated with microstructural defects.
