Researches on Fracture Surfaces Electrochemically Charged with Hydrogen

Abstract:

The present paper deals with the morphological alteration of fracture surfaces determined by hydrogen in the case of hydrogen based steels, through electrochemical methods as compared with similar samples of surfaces electrochemically uncharged or with welding deposits created by means of cellulose coated electrodes. Cellulose electrodes allow larger hydrogen quantities to be introduced into the metal deposited during the welding process. Hence, specific fractographic aspects are highlighted in view of interpreting prospective alterations caused by hydrogen based steels (13CrMo4.5 and S235 JR).
