Abstract
In this paper, the effect of hydrogen placement on the microdynamic wear mechanism of high niobium-titanium-aluminum alloys is investigated. Corresponding decreases and increases in loading force and displacement amplitude cause the microslip behavior of the alloy to change from partial slip to mixed slip. Slip type in mixed fire complete slip when you, the friction coefficient fluctuates. The average friction coefficient of hydrogen-placed alloys is small compared with that of non-hydrogen-placed alloys, the maximum wear marks are not obvious, and the oxidative wear is weak. The main wear mechanisms of non-hydrogenated alloys are adhesive wear, abrasive wear and oxidative wear. The main wear mechanisms of hydrogen-placed alloys are adhesive wear and abrasive wear.
