Sliding Friction of Steel Combinations

Abstract

Tribological characteristics of steel combinations are observed in this study using rotating tribometer. Experiments are done under different roughnesses ofpin slides on stainless steel disc for different operating conditionsCertain trends are obtained between friction and rubbing durations. During experiment, it is foundthat there are significant relationship between friction coefficient and operating parameters. In fact, at initial stage friction coefficients of tested material are increased at a particular level with time and finally the friction becomes steady for remaining investigation period. Studies indicate that lower values of friction are obtained with higher loads for SS 202 slides against different roughnesses ofmild steel counterface. Under similar conditions,higher values of frictions are found with higher values of sliding velocity. In addition to that, wear rates show higher values with higher load and velocity conditions. Tribological characteristics are varied for different roughnesses of pin materials under experimental ranges of two influencing prameters.
