Abstract
The friction and wear properties of a graphitized carbon material (disk) were investigated in air at temperatures from room temperature to 500°C. Thepin-on-disk type friction and wear testing machine was used with five different carbons as the pin materials.
The coefficient of friction (μ) and the specific wear rate (Ws) of the disk were measured. When graphitized carbon materials were used as thepin, p was low at all temperatures. On the other hand, when non-graphitized carbon materials were used as the pin, p became higher with temperature. The Ws-values of the disk were smaller at all temperatures when graphitized carbon materials were used as the pin. It is concluded that the graphitized carbon material (disk) shows better friction and wear properties when graphitized carbon materials rather than non-grapitized carbon materials were used as the pin.
