【摘要】 锌镍合金镀层具有优良的耐腐蚀性能，可以满足不断提高的防护性能要求。本文介绍了一种弱酸性锌镍合金电镀工艺。深入研究了镀液各组分的添加量及操作条件对镀层含镍量的影响，得到了优化的锌镍合金电镀工艺规范。利用本工艺可获得含镍量13％γ相的全光亮锌镍合金镀层。通过对镀层性能的测试，表明该镀层具有极好的耐高温性能及优良的耐腐蚀性。本文提出了与工艺相配套的彩色、白色、蓝白色钝化工艺。本文介绍的用光度法和光度滴定法相结合测定镀液中锌镍离子含量的方法，具有快速、准确、简便的特点，完全能够满足工艺研究及生产控制的要求。 本文提出的锌镍合金电镀工艺具有广泛的适用性和极大的市场价值。更多还原

【Abstract】 Zn-Ni alloy electroplating has a much better anti-corrosion nature. It can satisfy the ever increasing anti-corrosion demand. This thesis introduces a technology of weak acidic bath for electroplating Zn-Ni alloy. This thesis has made a thorough study on the influence of bath ingredients and the operating conditions upon the content of Ni in plating, and got an improved process regularity. With this process regularity, we can get a bright y phase Zn-Ni alloy plating with the content of 13% for Ni. From the testing of the properties of Zn-Ni alloy plating, it shows that this plating has a much better anti-high tempture property and an excellent anti-corrosion nature. This thesis introduces the process for getting a color, white and blue-white passivation coating that corresponds to the electroplating process.The spectrophotometric methodology .which has proved to be quick and accurate, is used to determine the content of Zn and Ni in the Zn-Ni alloy electroplating bath, It can satisfy the requirements of process study and production control.This Zn-Ni electroplating process has wide applications and great market value.更多还原
