In the context of developing the hydrogen sector, understanding the interactions between hydrogen and materials is a key challenge.
When hydrogen comes into contact with metallic materials, it can dissolve into the matrix and diffuse through it—a phenomenon known as permeation.
Hydrogen permeation measurements in metals have been developed at the CEA-Grenoble for over 20 years.
The objective of this post-doctoral project is to investigate these permeation phenomena when hydrogen is introduced at high pressure and when pollutants are present in the hydrogen.
The project will begin with the design and implementation of a new permeation test bench, which must enable high-pressure testing and precise control of impurity levels in the hydrogen.
Subsequently, the study will focus on the effect of pressure and impurities on hydrogen permeation in ferrito-pearlitic steels, using the previously developed test bench.
