Abstract
A solid lubricant 11 is formed by molding and firing powder that includes amorphous and self-sintering carbon material powder 12, graphite powder 13, and a binder 14. The solid lubricant has high material strength and hardness, and also excellent impact resistance and wear resistance.
Claims16
A solid lubricant formed by molding and firing powder that includes amorphous and self-sintering carbon material powder, crystalline graphite powder, and a binder,
- the solid lubricant comprises:
- amorphous carbon material particles formed by firing of the carbon material powder and sintered with each other, and crystalline graphite particles as main components, and further, an amorphous carbon binder component formed by firing of the binder, wherein
- content of the carbon material particles is highest in weight ratio, and
- the graphite particles are held by a sintered body formed by sintering the carbon material particles.
