Abstract: A method for producing a rare earth element sintered magnet which comprises applying a metal plating onto a Sm2Co17 type or R2Fe14B type magnet and then subjecting the resultant product to a heat treatment, or which comprises forming a metal oxide or nitride layer on the above metal plating layer or directly on the magnet. The method allows the production of a rare earth element sintered magnet being free from hydrogen embrittlement.
Abstract translation: 一种稀土元素烧结磁体的制造方法,其特征在于,在Sm2Co17型或R2Fe14B型磁体上进行金属镀覆,然后对所得产物进行热处理,或者在上述金属镀层上形成金属氧化物或氮化物层 层或直接在磁铁上。 该方法允许制造不含氢脆的稀土元素烧结磁体。
