Palladium coating on quenched-tempered martensitic steel for hydrogen electrochemical permeation tests

A coating process is proposed to obtain a thin palladium layer on high-strength steel. The quality of the layer is investigated by SEM observation. Potentiokinetic curves are performed to ensure no hydrogen formation during the coating process. Coated samples are tested by hydrogen permeation test and compared to non-coated samples. Permeation data analysis and boundary conditions are discussed based on permeation results and 1D simulations.
