Friction and wear characteristics of binary and ternary zirconia ceramics

The friction and wear behaviour of binary and ternary zirconia ceramics was studied in an unlubricated environment over a range of loads and sliding speeds. In these tests, ternary zirconia ceramics based on the ZrO2-CeO2-Y2O3 system were seen to show very low friction coefficients and wear rates compared with the other binary zirconia systems investigated, with a coefficient of friction typically about 50% that of other (binary) zirconia ceramics, and a wear rate of about 1% of that of tetragonal yttria-doped zirconia. During slide testing of zirconias a transition from a low wear regime to a high wear regime was observed with increasing sliding velocity and load. SEM was used to identify the wear mechanisms.
