Abstract

The corrosion wear behaviors of a Fe-based bulk metallic glass Fe _66.7C _7.0Si _3.3B _5.5P _8.7Cr _2.3Al _2.0Mo _4.5 against Si ₃N ₄ ceramic ball was studied in a 3.5% NaCl solution and using a unidirectional tribometer with the ball-on-disk configuration. During friction process, the Fe-based BMG showed tribochemical reaction with the 3.5% NaCl solution. Wear occurred mainly through an abrasive wear mechanism and corrosive wear effects. The overall average friction coefficient was in the range of 0.18 to 0.25 according to the test conditions and slightly decreased with increasing load. The wear resistance of the BMG was better than that of the conventional bearing steel, demonstrating the potential of the BMG as a viable engineering alloy for anti-corrosive wear applications.
