ABSTRACT:
Described herein is a chromium oxide-based ceramic material obtained by sintering a powder mixture consisting of chromium oxide powder and 0.1-90 wt % of chromium carbide powder based on the total amount of the powder mixture. The sintered product has not only a small coefficient of friction over a wide temperature range from normal to high temperature but also excellent deflection resistance and high density with less pores, which are suitable for application as a sliding material.
