摘要
采用赫尔槽试验研究了镀液中各种成分的作用及工艺条件,用扫描电镜( SEM )观察了镀层形貌。研究发现,在酸性光亮镀锡镀液中添加铈盐和自制的光亮剂,可获得一种铈含量达0.5%的锡铈合金镀层,该镀层外观光亮、平整。通过镀层性能测试,并与纯锡镀层性能进行比较,发现:当镀层厚度大于5μm时,锡铈合金镀层表面致密均匀,结晶细致光亮;其抗氧化性、耐蚀性、防变色性能及可焊性明显优于纯锡镀层,解决了纯锡镀层在焊锡时易发生变色,提高了焊接温度。
Abstract
With Hull cell experiment , the function component in the bath and technological conditions of bright acidic Sn-Ce alloy were studied .The appearance of deposits was tested by SEM .It was found that a smooth and bright plating layer of Sn -Ce alloy with 0 .5% Ce was obtained by adding cerium salt and the homemade brightener in the tin electroplating bath .The coating was tested and compared with pure tin electroplating plating . The results showed that when the plating was thicker than 5μm, the surface of the Sn -Ce alloy plating was uniform and dense with fine and bright crystals .It was more antioxidant , corrosion-resistant, solderable and resistant to change color than pure tin plating .
