摘要： Disclosed herein is a high temperature-resistant and abrasion-resistant sliding member of graphite-metal borides showing a friction coefficient of 0.01 to 0.09 and a specific amount of abrasion of 1.0 to 4.0.times.10.sup.-8 mm.sup.2 /kg under the measuring conditions of a load of 20 kg/cm.sup.2 and a sliding velocity of 5 m/min at an atmosphere temperature of 300.degree. C., a bending strength of 230 to 900 kg.f/cm.sup.2 and a Shore hardness of 28 to 45, produced by sintering (a) 70 to 93% by weight of amorphous carbon powder, (b) 5 to 20% by weight of at least one boride of a metal of IVa group, Va group of VIa group of the periodic table and (c) 2 to 10% by weight of powdery natural graphite, powdery Kish graphite or a mixture thereof.
