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 andor subsequent removal from steel by 1 Porous deposits and subsequent baking to remove andor 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.
