FIELD: powder metallurgy, namely production of antifriction layer of sliding bearing assemblies, possibly manufacture of bearing assemblies of submerged electrically driven pumps. ^ SUBSTANCE: method comprises steps of working base of bearing till roughness degree 320 - 160 micrometers; placing antifriction material onto worked surface and inserting it into furnace; then soaking it in furnace in protection-reduction medium at first at temperature lower than melting temperature of antifriction material till complete reduction of oxides on surface and then at melting temperature of antifriction material. Then cooling is realized at crystallization from downwards to upwards. ^ EFFECT: improved quality of bearing assembly. ^ 5 cl, 3 dwg |
