    摘要:

    以A3 钢为基底进行化学复合镀Ni-Co-P,采用正交试验法得到了一种Ni-Co-P 的最佳配方及
    工艺条件,并对镀层的形貌、硬度、厚度、结合力、耐蚀性等进行了检测和分析。实验得出了最佳配方及工艺条
    件:硫酸镍35. 0 g/ L,硫酸钴4. 0 g/ L,次亚磷酸钠30. 0 g/ L,柠檬酸三钠60. 0 g/ L,硼酸35. 0 g/ L,乳酸12. 0
    mL/ L,十二烷基苯磺酸钠0. 05 g/ L,硫脲2 mg/ L,pH 值为7. 0,温度90益,施镀时间2 h。在该条件下,镀层沉
    积速率较快,可达89. 83 g/ (m2·h),镀层具有较强的耐蚀性,硫酸铜点滴时间可达285 s;该镀层表面分布均
    匀,孔隙率分布较小,与基体结合力较好。

    Abstract:

    A3 steel is used as the base material steel in electroless Plating of Ni-Co-P, The best formula and
    process conditions are acquired by using the orthogonal experiment methods. The morphology,corrosion resistance, hard鄄
    ness,thickness and binding force of coating are tested and analysed. The optimum formula and the technological conditions
    are required as follows:35.0 g/ L NiSO4·6H2O, CoSO4·7H2O 4.0 g/ L, NaH2PO2·H2O 30.0 g/ L, Na3C6H5O7·2H2O
    60.0 g/ L, H3BO3 35.0 g/ L C3H6O3 12.0 mL/ L, C18H29NaO3S 0.05 g/ L, CN2H4S 2 mg/ L, pH value of 7.0, the tempera鄄
    ture of 90益, and the plating time of 2 h. Under this condition, the deposition rate is faster, up to 89.83 g/ (m2·h), the
    coating has stronger corrosion resistance, copper sulfate drip experiment time is 285 s; the surface of the coating is smooth
    and uniform;the distribution of porosity is smaller;there is better binding force with substrate.
