Visualization of Hydrogen on Ti-6Al-4V Using Hydrogen Microscope

The two-dimensional distribution of hydrogen on Ti-6Al-4V gives very important information on the environmental embrittlement mechanism. The scanning-electron-stimulated desorption ion microscope, the so-called hydrogen microscope, can be used to visualize hydrogen on solid surfaces. In this study, we attempt to visualize hydrogen on Ti-6Al-4V alloy using a hydrogen microscope. As a result, the hydrogen distribution on the Ti-6Al-4V surface was clearly observed.
