Abstract
Wear behaviors of a Fe-based bulk amorphous alloy with more 3MPa yield strength against AISI 304 disc were studied in different environment using a unidirectional tribometer. Friction behaviors were also investigated in the state of both amorphous pin on amorphous disc test set and the amorphous pin on AISI 304 disc test set with surface temperature using thermocouple embedded pin. Wear mechanisms of a Fe-based bulk amorphous alloy have been proposed based upon the microstructural analysis and surface temperature measurements during pin-on disc friction tests in ambient atmosphere and in distilled water, respectively. Delamination from the smooth friction surface was the main wear mechanism during the friction test in ambient atmosphere, while brittle fracture morphologies were apparent on the friction surface formed in a distilled water condition. Based upon the surface temperature measurements, difference in the heat removal efficiency on the friction surface due to different atmospheres was suggested to cause distinct wear mechanisms.
