Production of Surfacing Materials Based on an AO20-1 Antifriction Alloy Hardened with Micron- and Submicron-Sized Ceramic Particles
摘要
Abstract
A technology for producing surfacing materials for the subsequent formation of functional composite layers on steel bases of friction units is presented. Composite surfacing rods are produced by extrusion of a powder compact made of AO20-1 antifriction matrix alloy granules and ceramic powders of micron (SiC) and submicron (TiC) sizes. The conditions of producing matrix alloy granules and composite mixtures and extrusion are described.
