Résumé

The effect of hydrogen on the mechanical properties of the super duplex stainless steel is examined using in situ electrochemical nanoindentation (ECNI) tests. Within the ECNI, which is a nanoindenter combined with an electrochemical setup, the nanoindentation can be made on a surface that is immersed in an electrolyte and in situ electrochemically charged with hydrogen. In situ electrochemical nanoindentation testing captures the change in the onset of plasticity (pop-in load level) as well as the change in the hardness due to the absorption of the atomic hydrogen.
