THE REDUCTION-DIFFUSION PROCESS IN PREPARATION OF SAMARIUM-COBALT PERMANENT MAGNETS

【摘要】 <正> The fact that the reduction-diffusion procedure can be used to prepare Sm-Co permanent magnet of high quality is well known. In order to simplify the technology, as well as to provide sufficient data for exploring new-type permanent magnets and other metallic materials (e. g. hydrogen-storage material, etc.) on basis of rareearth metals, a further investigation on the process of reduction-diffusion was carried out in the present work.更多还原
