摘要：

Two cladding methods for NdFeB powders, i.e., the modified organic silicon (MOS) cladding and the dichromate passivation reducing (DPR) cladding are exploited respectively for the preparation of polymer-bonded magnet and metal-bonded magnet. The effects of their cladding conditions and coating compositions, together with the effects of modifying additives are discussed. Compared with the conventional polymer-bonded magnet, MOS polymer-bonded sample shows better comprehensive properties including magnetic properties, compression strength and corrosion resistance. Providing a feasible method for Nd-Fe-B type metal-bonded magnet, DPR Sn-bonded NdFeB magnet presents superior compression strength despite a little inferior magnetic property.
