Polarization experiments and a potentiostatic pulse technique have been used to show that a monolayer coverage of zinc effectively inhibits the absorption of hydrogen into Monel K500. By depositing a monolayer of zinc on Monel K500,the hydrogen evolution reaction and hydrogen ingress flux rate were reduced by 60%.
