Introduction
The main types of antifriction materials produced by Moscow Electrode plant consist of carbon (burnt and graphite, impregnated and non-impregnated with metals), graphite-fluoroplastic, graphite-plastic and with additives. Antifriction materials based on carbon are used to manufacture the parts for blocks of machine friction as well as the devices and aggregates operating without lubricant, and also bearing sockets, piston rings, rings for face and section thickenings, guides, etc. Carbon antifriction materials are chemically resistant in many aggressive gas and liquid media. They are stable in almost all acids (up to the acid boiling point), in salt solutions, in all organic solvents and partially stable in concentrated solutions of caustic alkalis. Antifriction carbon burnt materials are characterized by better hardness and strength but worse heat conductivity to compare with graphite materials. Their coefficient of heat expansion is lower than metals. The friction coefficient is equal to 0.05-0.10. The efficiency of carbon antifriction materials considerably depends on the contents and humidity of gas medium. If there are films and drops of condensed moisture on the friction surface, the friction coefficient of carbon antifriction materials increases approximately tenfold and the friction coefficient of the materials impregnated with metals twofold.
When designing and producing parts made from antifriction materials it is necessary:
         to prepare the parts with no abrupt cross section transitions and stress concentrators (slit grooves, holes and threads) because of the materials friability and small distortions up to destruction;
         to note that the parts must only work under the conditions of compressive or bending loads;
         to note when choosing settings and slots the difference in the coefficients of heat expansion for carbon materials and countershanks;
         to ensure at high slipping speeds the intensive take-off of friction heat;
         to exclude the mechanical pressing of carbon bearing sockets;
         to give priority to the hot setting of a socket into metal rings;
         to make the parts from antifriction materials with the allowances like in metal parts;
         to process the materials of all grades (except AO) with the usual instrument;
         to process the material of grades AO with the instrument made of hard alloys;
         to ensure the smoothness of antifriction parts 6, upon special polishing 10, and the smoothness of metal countershanks - 10.
