    Abstract

    The manufacturing processes of titanium and aluminum alloys involve hydrogen wet conditions. The current research investigates the effect of such hydrogen on the mechanical and tribological performance of these alloys. Experimental approaches include the development of a hydrogen charging method, mechanical testing using a small punch tester, and the testing of friction and wear behavior using a tribometer. The results show that for both alloys, no hydride was formed. The molecular hydrogen did not have any visible effects on aluminum; however, the titanium alloy showed profound effects in its mechanical properties, with a reduction in strength. The hydrogen had no significant effect on the tribological properties of titanium or aluminum specimens. The current research shows a novel way to test for the effects of hydrogen in wet conditions on the mechanical strength of materials. The research outcome could aid design engineers in their selection of materials in hydrogen environments.
