FIELD: forming antifriction surfaces in friction pairs. SUBSTANCE: grooves 0.1 to 1000 mk deep are made on friction surface; ratio of total area of friction surface but for area of grooves to total area of grooves ranges from 0.2 to 2.0. Grooves are filled with antifriction material containing intermetallic compounds of non- ferrous meals reinforced with ultra finely dispersed diamonds. EFFECT: enhanced efficiency. 2 tbl
