Abstract

The invention relates to the technical field of grain boundary diffusion technologies, in particular to a vacuum reaction system for a grain boundary diffusion technology. The vacuum reaction system comprises a vacuum furnace capable of heating a workpiece, a furnace body of the vacuum furnace comprises a hollow furnace shell, and the outer side of the vacuum furnace is provided with a rapid cooling device; and the rapid cooling device comprises a water supply pipe and a water return pipe of which one ends are sealed, and the water supply pipe and the water return pipe communicate with the interior of an cavity inside the furnace shell through communication pipes. The vacuum reaction system has the effects of increasing the cooling speed of sintering equipment and achieving rapid cooling of the sintering equipment.

Description

technical field [0001] The present application relates to the technical field of grain boundary diffusion technology, in particular to a vacuum reaction system for grain boundary diffusion technology. Background technique [0002] At present, in the industrial production of the magnetic material industry, it is generally used to increase the coercive force by doping heavy rare earth materials together in the smelting process. In order to obtain higher performance of the magnet more effectively, the process of infiltration of heavy rare earth grain boundaries is adopted to effectively reduce the usage of heavy rare earth elements, so that heavy rare earth elements only exist in the grain boundaries, so that it is easier to obtain high-performance magnets. [0003] The existing heavy rare earth infiltration process mainly includes: forming a layer of thin film containing heavy rare earth elements on the surface of the workpiece by evaporation or coating, and then performing hi...
