钕铁硼永磁体为粉末冶金,与光亮镀镍镀层结合力不好。而且光亮镍镀层的孔隙率较高,这两个因素严重影响其耐腐蚀性能。日本往友公司研制的钕铁硼永磁体光亮镀镍,表面光滑、细致,结合力良好。本文研究钕铁硼永磁体光亮镀镍的工艺流程,找出影响这两个因素的原因,从而提高镀层质量。 Neodymium iron boron permanent magnet powder metallurgy, and bright nickel plating adhesion is not good. And bright nickel coating porosity higher, these two factors seriously affect their corrosion resistance. Japan Friends of the company developed NdFeB bright nickel plated, smooth surface, meticulous, good bonding. This paper studies the bright nickel-plated NdFeB permanent magnet process, find out the reasons that affect these two factors, thereby enhancing the quality of the coating.
