摘　　要：研究了在烧结钕铁硼永磁材料进行表面处理所使用的酸洗液中加入添加剂,可有效减缓材料性能衰减的酸洗工艺。在同一操作水平下,选择几种酸洗添加剂分别进行酸洗处理和电镀,然后分别对磁性能的影响进行测试。结果表明,SDC作为钕铁硼永磁材料的酸洗添加剂,所获得材料成品的磁通值最高;明确指出酸洗添加剂在酸洗过程中的意义,并对进一步研究和控制指明了方向。A pickling process in which additives are added to the pickling solution used for surface treatment of sintered NdFe B permanent magnet materials can effectively slow down the attenuation of material properties.At the same operating level,several pickling additives are selected for pickling treatment and electroplating respectively,and then the influence of magnetic properties is tested respectively.The results show that SDC,as pickling additive of Ndfe B permanent magnet material,has the highest magnetic flux value.The significance of pickling additives in pickling process is clearly pointed out,and the direction of further research and control is pointed out.
