In order to study the distribution behavior of hydrogen in metals under the condition of H2S corrosion, a layer-stripping micro-hardness test was turbo air m3f72-3-n designed to analyze the hydrogen distribution along the depth of hydrogen-charged 45 high-quality structural carbon steel at three different hydrogen sulfide concentrations and four corrosion periods in this study.The results show that there is a terminal solid solubility of hydrogen in the metal for hydrogen sulfide solutions over various concentrations and corrosion periods.A hydrogen-saturated layer is produced by hydrogen diffusing through click here the metal from an unsaturated state to a fully saturated state.The hydrogen-saturated layer is not affected by the concentration of the corrosion, but its thickness increases as the corrosion period increases.In this way, we established a new hydrogen diffusion model in metals.
