摘要
针对Ｎｄ－Ｆｅ－Ｂ永磁材料组成元素钕（Ｎｄ）的氧化还原电势较负（－２．４４Ｖ）的特点，通过探索性试验，详细研试了Ｎｄ－Ｆｅ－Ｂ合金产品除油、出光和浸镀工艺的效果和工艺参数。结果表明，按照确定的工艺规范进行施镀，显著地提高了镀镍层与基体之间的结合强度，改善了镀镍层的质量。
In accordance with the oxidation-reduction electric potential of Nd,which was the composition element of Nd-Fe-B permanent magnetic materials,is comparatively negative(-2.44V),effects of degreasing,producing brightness and immersion plating technologies as well as parameters of the Nd-Fe-B productors were study by the exploration tests.Results indicated that binding intensity between nickel-plating and base metal is prominently enhanced,quality of nickel-plating is improved when plating on defined technology,
