Effects of material pair properties on the frictional behavior of metals

摘要: The objective of this work was to investigate the validity adhesion theory and mechanical interaction view point in describing frictional behavior metals. Specifically, experimental conducted relative importance material compatibility hardness ratio on friction wear various metals dry sliding condition ordinary laboratory environment. Initial steady state coefficients were measured using both pin-on-disk pin-on-reciprocating testers for metal pairs, which strategically selected based their ratio. characteristics also observed following experiments. results showed that had no significant correlation with either initial or coefficient. As ratio, pairs very large differences values resulted high Overall, it factors such as motion, whether unidirectional bi-directional, particle dynamics found be more critical than Furthermore, among several properties analyzed, coefficient highest shear modulus while hardness.
