· The hydrogenated NdFeB powder that needs to be processed by this unit will be supplied by hydrogen decrepitation of different forms of scrap.The production of the hydrogenated powder, which will be processed using the equipment described in this tender, is based on a patented technology developed at the University of Birmingham, in which ... Hydrogen Embrittlement Failure of NdFeB Magnet · The hydrogen embrittlement mechanism of NdFeB magnet is same as its powder making process. The finished NdFeB product also does not work well together with hydrogen, and that is why the magnet is not recommended in the hydrogen atmosphere. The disintegration process will be highly accelerated under the elevated temperature and pressure. Recycling of bonded NdFeB permanent magnets using ionic ... NdFeB powder and the ionic liquids was observed. A batch of PA0-bonded magnets was treated with an ionic liquid
