The Influence of Graphene Orientation on the Friction and Wear Properties of Si3N4/TiC Based Composite Ceramic Tool Materials
Tribological performance of Si N/TiC based composite ceramic tool materials containing 5wt%graphene platelets with different orientation angle of graphene(0°,15°,30°,45°,60°,90°)have been investigated by pin-on-disc tests in dry sliding conditions.The results revealed that graphene orientation angle has obvious influence on the friction coefficient and wear rate.The friction coefficient and wear rate of Si3N4/TiC based composite ceramic tool materials with the 30°orientation angle are 0.46 and 4.29×10-6mm3/N·m,respectively.Which is decreased by 31.3%and 63%compared with that of 0°orientation angle.The improved wear behavior can be explained by the distribution uniformity of adhered tribofilm which is created by grahene and iron oxides and the combined effect of graphene pull-out and the contact area between graphene and the friction surface.
