摘要
A method for manufacturing a high-performance NdFeB rare earth permanent magnetic device which is made of an R—Fe—Co—B-M strip casting alloy, a micro-crystal HR—Fe alloy fiber, and TmGn compound micro-powder, includes steps of: manufacturing the R—Fe—Co—B-M strip casting alloy, manufacturing the micro-crystal HR—Fe alloy fiber, providing hydrogen decrepitating, pre-mixing, powdering with jet milling, post-mixing, providing magnetic field pressing, sintering and ageing, wherein after a sintered NdFeB permanent magnet is manufactured, machining and surface-treating the sintered NdFeB permanent magnet for forming a rare earth permanent device.
