The friction and wear behaviour of SiC, Si3N4 and SiC/Si3N4 composite ceramics were investigated with oscillating sliding (gross slip fretting) at room temperature. The influence of counter body material and the humidity of the surrounding air was studied with a ball-on-disc configuration with different ball materials (1000Cr6, Al2O3 SiC and Si3N4). The effect of RH on friction is marginal with exception...
Amorphous SiCN ceramics were prepared in a laboratory scale as disk shaped specimens with 10mm diameter and 0.3mm thickness. The friction and wear behaviour was characterised in gross slip fretting tests under unlubricated conditions at room temperature against steel (100Cr6) and ceramic (Al 2 O 3 ). Tests with a ball-on-disk contact were performed in laboratory air with different...
The friction and wear behaviour of a new developed, pressureless sintered TiB 2 ceramic was studied in comparison to SiC against SiC and Al 2 O 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...
The tribological behaviour of single‐phase SiC as well as both SiC–TiC and SiC–TiC–TiB2 composite materials sliding against aluminium oxide has been investigated at room temperature with regard to the formation of wear‐reducing interfaces. The experiments were carried out in dry air for reasons of excluding the strong influence of water vapour. The introduction of the titanium phases into the SiC...
