研究了稀土元素对镍硼镀层工艺及性能的影响。结果表明，稀土元素在化学镀镍硼过程中起重要作用；添加适量稀土元素，可改善镀层的成分与性能，特别是可降低镀层的接触电阻和提高化学稳定性。该镀层材料可代替镀金和镀银，成为良好的弱电接点材料。
The effects of rare earth elements on the process and properties of Ni-B coatings were studied. The results show that rare earth elements play an important role in the process of electroless Ni-B plating. Adding appropriate amount of rare earth elements can improve the composition and properties of the coatings, especially reducing the contact resistance and chemical stability of the coatings. The coating material can replace gold-plated and silver-plated, become a good weak electrical contact materials.
