【Abstract】 The corrosion resistance of an altasonic-aid electroless pre-plated NdFeB permanent magnet was studied without and with a secondary electroless Ni-P plating with higher P content.Macrostructural analysis was also performed by means of SEM and X-ray diffraction.The resutls show that the top coat is very effective for improving corrosion resistance of Nd-FeB permanent magnet.更多还原
