Impregnation method of composite bushing and related knowledge

In porous material matrix impregnated solid lubricant constitutes impregnated solid lubricating composite bearings, stored in the internal solid lubricant with bush bearing wear to keep the friction surface of the supply of solid lubricant. A typical composite bearings is carbon graphite base material impregnated with a soft metal, Teflon or an inorganic material.
Impregnation methods are:
1. The impregnated material becomes a molten state vacuum impregnation.
2. curable liquid as a carrier, which is impregnated impregnation was placed.
3. volatile liquid as a carrier, wherein the dispersion was impregnated impregnation, and then the liquid evaporate.
4. impregnation impregnated was vaporized. Impregnate only lubricate, but also increase the strength of the matrix material.
