On the influence of test parameters on friction and wear of ceramics in oscillating sliding contacts

Abstract

The tribological behaviour of different ceramics in contact with steel was studied for the case of oscillating sliding motion with a ball‐on‐disc apparatus. The influence of several test condition parameters was investigated by a systematic variation of the stroke, frequency, and normal load at room temperature in laboratory air at different levels of relative humidity. Each of the four parameters was varied in three stages. While the coefficient of friction was only mildly influenced by the operational variables, the coefficient of wear showed great variations and depended strongly on the humidity of the surrounding air. The effect of the operational variables and of the humidity on friction and wear varied for the different materials under investigation.

Oil Free Machinery and “Zero Wear”- Dream or Reality?

“…The resolution limit of the wear rate for the rotating specimen corresponds to about 10 -9 mm 3 /Nm. , were performed on a test rig for oscillating motion with small amplitudes, described in more detail in [23]. The non rotating ball is fixed at the top of a lever and is pressed against the surface of the disk as is shown in Fig.…”
