Abstract

In this paper, we investigated the wear lift, wear rate, and its transition on the Hertz pressure. In the experiment, we used TiAlCrN coating deposited by the sputtering technique and ball diameter of 10mm, 7.94mm and 4.76mm for the various Hertz pressure. Ball-on-disk sliding tests wire performed under the unlubricated condition. As the diameter of a ball decreased, the failure load of TiAlCrN coating decreased. However, a good correlation was observed between the wear life and Hertz pressure, and all ball specimens showed the infinite wear life at about 450MPa. In measurement of wear rate, as the diameter of the ball inclosed, the wear transition appeared in bigger load. However, a good correlation was observed between the wear rate and Hertz pressure. The transition appeared in the range from 550MPa to 600MPa at all ball speimens.
