Additively-manufactured metal alloy components must provide adequate resistance to corrosive service environments.   This research will investigate the corrosion and environmentally-induced cracking (stress corrosion cracking, hydrogen embrittlement, etc.) susceptibility of additively manufactured alloys and components in room-temperature aqueous environments.  Experimental methods include slow-strain-rate tensile testing with simultaneous electrochemical studies, polarization resistance, electrochemical impedance spectroscopy, and scratch repassivation.  Experimental polarization and impedance spectroscopy measurement will be compared with CALPHAD-based models predicting phase stability regions as functions of potential and current (e.g., E vs pH diagrams).
