Extreme operating conditions of machines and units (high and low temperatures, high velocity and pressure, aggressive working environments, vacuum, etc.) do not allow the use of materials in friction with the oil due to burnout of the latter, or the pollution of technology products, and many other negative effects. Hence there is an urgent need for new classes of anti-friction materials that can operate without lubrication in friction. Achieve greater longevity tribology application, including in the joints brake linkage is possible through the development of a new composite material based on nanopowders. The use of composite materials will reduce the amount of friction and heat in tribology applications and reduce heat loss to the environment. Composite materials offer high-performance, used in areas that require high stability and durability in long-term friction. High mechanical damping capacity of composite materials to avoid unnecessary congestion tribology application. This product is made of composite materials work very smoothly and almost silently. The paper discusses some features of the tribological contact details, conducted a literary analysis of existing materials for friction and the proposed structure of the new composite material based on transformational-strengthened zirconium dioxide matrix impregnated with graphite, made the selection of optimum sintering conditions of the new composite material selected composition, carried out detailed tribological research produced material studied the effect of structure and structural changes of the surface friction and wear of ceramics and the effect of porosity on the strength and tribological properties of the developed material.
