Inhibition of Hydrogen Absorption during Plating of High Strength Steels.
Abstract
Hydrogen absorbed by steel parts during the cadmium plating process can cause cracking failures in service. This feasibility study was concerned with the effects of precoating steel with an electroactive coating on the amount of hydrogen absorbed during subsequent cadmium plating. Redox couples having rather negative standard redox potentials were successfully immobilized on steel surfaces. However, these coatings either had no effects or increased the amount of hydrogen absorbed during the cadmium plating step. Possible reasons for this behavior are given in this report along with other pertinent experimental findings. Alternate approaches to solving the hydrogen absorption problem are discussed. (Author)
