Abstract

In this paper, the obtained analytical results are first briefly summarised. Next, some experimental results are shown which were developed using finished ceramic surfaces of ZrO2 and Al2O3 together with SiC. Furthermore, comparison of obtained experimental results with theoretical analyses and approximate equations introduced in the preceding works was made. The main conclusions are as follows. (1) Little difference can be seen in appearance between the experimental and calculated displacement behaviours, although frictional force of SiC is higher compared with those of other two ceramics and the slope of the curve after macro-slip of SiC is greater than those of the others. (2) Experimental values of tangential stiffness r(g) at the start of increasing the tangential force lie between calculated values by the two contact models. (3) Experimental values of tangential displacement delta(cmax) at the start of macro-slip are larger than those calculated by the two contact models and this is more evident for ZrO2.
