摘　　要：阐述了在优化阴极电泳工艺参数和改进阴极电泳设备后,可以获得耐腐蚀性能较好的粘结钕铁硼磁体。在最佳工艺条件下,粘结钕铁硼磁体涂层具有耐高温高湿性大于480h和耐盐水性大于60h以上的防腐蚀性能。新的阴极电泳工艺参数及改进的设备已应用于批量生产,年处理能力达到千万件。The cathodic electrophoresis process parameters were optimized and its devices improved so that the captioned magnet has better corrosion resistance. After treatment under optimum conditions, the temperature and humidity fast time of the magnet can reach 480 hours and its brine fast time 60 hours. The optimized parameters and improved devices are already put into real use with the annual processing capacity up to ten million pieces.
