NdFeB永磁体阴极电泳涂漆工艺

Cathodic Electropainting Technology for Sintered NdFeB Permanent Magnet

介绍了阴极电泳涂漆的成膜机理和工艺,分析了固体份、电导率、pH值、电压、槽液温度及烘烤固化对NdFeB磁体的电泳涂漆质量的影响,NdFeB磁体通过阴极电泳工艺涂环氧树脂漆表面获得一层均匀光滑的涂层,此涂层具有优异的耐蚀性。

Electrodeposition mechanism and process of cathodic electropainting were described in this paper. The effects of solids, conductivity, pH value, voltage, bath temperature and baking on the electropainting of NdFeB permanent magnet were discussed. The epoxy electropaint of NdFeB permanent magnet has good corrosion resistance.
