..., the scanning kelvin probe (SKP), is appropriate for local detection of very low hydrogen amounts. The principle of hydrogen detection by SKP is based on changes in the measured surface potential. When hydrogen is absorbed on the H entry side and diffuses through the specimen, it interacts with the oxide layer...
