EVALUATION OF CADMIUM PLATING SYSTEMS FOR HYDROGEN EMBRITTLEMENT

Abstract

A cooperative testing program to compare the hydrogen embrittlement characteristics of several available plating systems was conducted by ARTC project 6-61. Eleven plating systems that showed promise of being non- embrittling were selected for evaluation. The plating systems evaluated approached the problem of reduction of hydrogen entry and/or subsequent removal from steel by: (1) Porous deposits and subsequent baking to remove and/or distribute hydrogen absorbed; (2) High efficiency (low hydrogen producing bath) with subsequent baking; (3) Suppression of hydro gen formation by additives; (4) Organic baths with no hydrogen formation; and (5) Organo brush plating baths. The .003 in. notch root radius tensile specimen and the Douglas ring specimen evaluated in ARTC 13-59 were selected to test and evaluate the plating systems.
