Tribological performance of SiC and TiB 2 against SiC and Al 2O 3 at low sliding speeds
The friction and wear behaviour of a new developed, pressureless sintered TiB 2 ceramic was studied in comparison to SiC against SiC and Al 2O 3 balls under unlubricated conditions at room temperature. Special attention was paid to the influence of relative humidity on friction and wear results. For...

Summary: | The friction and wear behaviour of a new developed, pressureless sintered TiB
2 ceramic was studied in comparison to SiC against SiC and Al
2O
3 balls under unlubricated conditions at room temperature. Special attention was paid to the influence of relative humidity on friction and wear results. For both ceramics the coefficient of friction against both ball materials decreases with increasing humidity and is higher in tests against alumina than against SiC. The wear rate is affected significantly by humidity and decreases by one order of magnitude for Al
2O
3/SiC system and by 2 orders of magnitude for SiC/SiC system. For TiB
2 wear rates are nearly not affected by humidity against both ball materials and are much smaller than for SiC. |
