摘要：

The friction and wear properties of oil-retaining porous silicon carbide for sliding contact in air were investigated by using a pin-on-disk friction machine. The friction tests were carried out under the conditions of various sliding velocities (0.13 to 0.57 m/s) and various combinations of oil-retaining porous silicon carbide and dense silicon carbide (pin/disk). In the dense SiC/oil-retaining porous SiC system, the lowest and most stable friction coefficient and the least wear were obtained independent of sliding velocity. This is due to the lubrication effect of the oil supplied from the oil-retaining porous SiC disk at the friction interface. The friction and wear mechanisms of these ceramics were classified into four modes depending on the relation between friction coefficient and specific wear amount and SEM observation of frictional surfaces.
