Abstract: In this paper, a ball-on-flat plate test is performed under dry condition. A cold-rolled high strength steel plate is used for a flat specimen, and AISI52100, ZrO2, Al2O3, and Si3N4 balls are selected as a counterpart. The kinetic friction coefficient is determined and one-way analysis of variance (ANOVA) is employed. Experimental results show that the steady-state friction coefficient of AISI52100 balls ranges from 0.56 to 0.58 on a cold-rolled high strength steel plate. The friction coefficient of ZrO2 balls is lower than those of AISI52100, Al2O3, and Si3N4 balls. Results of ANOVA show that counterpart material plays a statistically significant role in determining the steady-state friction coefficient, whereas normal force does not make a critical impact on the steady-state friction coefficient within the range of 12 N and 50 N. Finally, we found the linear relation between the steady-state friction coefficient and the maximum contact pressure.
