METHOD OF THERMOCYCLIC DIFFUSION OF METAL POWDERS FOR WORN-OUT SURFACE OF BRONZE PLAIN BEARING BUSHES Russian patent published in 2014 - IPC B23P6/00 C23C24/10 

FIELD: process engineering.

SUBSTANCE: invention relates to reconditioning of plain bearings. Metal powders are diffused to plain bearing bush surface to be reconditioned. Cyclic heating of the bush and bronze-base powder is performed to the powder melt temperature and powder diffusion in bush metal. Bush is held at the temperature of initial diffusion process. Then, it is cooled to the phase sintering temperatures and held thereat. Secondary cooling is performed to powder melt temperature and held thereat for build-up of reconditioned diffusion ply and said ply is cooled down.

EFFECT: accelerated and simplified thermal diffusion at reconditioning of plain bearings.
