Production of surfacing materials based on antifriction alloy AO20–1, hardened with ceramic particles of micron and submicron sizes

The technology of obtaining surfacing materials for the subsequent formation of functional composite layers on steel bases of friction units is presented. Composite surfacing rods were obtained by extrusion of a powder compact from granules of matrix antifriction alloy AO20–1 and ceramic powders of micron (SiC) and submicron (TiC) sizes. The modes of obtaining matrix alloy granules, composite mixtures and extrusion are given.
