Abstract

In this study, the friction and wear properties of Fe-Mo type alloy disk specimens were investigated against ASTM 52100 steel balls under the lubrication of ethyl-alcohol using a reciprocating Optimol SRV tribometer. It was found that the Fe7Mo6-based alloy disk specimens with a composition of Fe-42at% Mo exhibited more stable and lower friction coefficients than the Fe and Mo disk specimens.In addition, the friction coefficients of Mo disk specimens rapidly increased 1.8 ks after starting their friction tests, while the friction coefficients of Mo disk specimens were rapidly reduced 2.4 ks after starting their friction tests.
