Are corrosion, hydrogen absorption and mechanical strength of steel exposed to inhibited acid solution interrelated? Available to Purchase

Introduction Corrosion inhibitors are used during pickling, oil‐well acidification and in other process industries to control corrosion and hydrogen absorption by steels. The suitability of an inhibitor is judged by measuring the corrosion rate and by the hydrogen absorbed by the material during the operation in the presence of inhibitors. It is generally believed that the efficacy of an inhibitor in controlling hydrogen absorption increases with its increase in corrosion mitigatory properties. This principle is true for the inhibitors which function by uniform film formation but fails in the case of poisons such as compounds of As, S, P and Sb, which strongly polarize the recombination step of the hydrogen evolution reaction on metal surfaces:
