状である。The expanded graphite is pure graphite, and the copper heat of graphite,
It has excellent properties such as chemical resistance, weather resistance, small thermal expansion, and excellent solid lubrication, and is often used as a honeymoon member. However, even expanded graphite, which has excellent 'fc% properties, has some weaknesses, such as corrosion of mating metals such as rocks and shafts in poor atmospheric conditions; 4. Adhesion to the material surface (7) Gradually increases the frictional coefficient, resulting in seizure, which, combined with a lack of consideration at the time of application, often causes problems and makes it difficult to take countermeasures. The current situation is that

に一掃することができる９、When used as a conventional expanded graphite 8-rotation shaft packing, expanded graphite particles transfer and adhere to the shaft surface as the shaft rotates and slides, and the expanded graphite grows like a film on the shaft surface.
A phenomenon that leads to a sudden increase in frictional force due to a precipitous abrasion 8 on the expanded graphite surface Q in contact with this may be observed, but the composite material according to the present invention completely suppresses this phenomenon. It is. In the present invention, the metal particles deposited on the surface of expanded graphite completely prevent the expanded graphite from transferring or adhering to the sliding surface of the shaft and maintain a clean surface, thereby reducing the coefficient of friction. Stay stable. In addition, even if the friction surface temperature rises extremely under severe load conditions, the present invention provides protection by using vapor-deposited metal.
Alternatively, even if the remaining vapor-deposited edge melts, it forms a fluid film between the sliding surfaces, so the seizure phenomenon up to n- can be completely wiped out9.
