化学镀镍工艺条件的计算机优化

为研究化学镀镍最佳工艺条件,以LM-4铝为基体,讨论了均匀设计及计算机优化在化学镀镍中的应用.试验按5因子、10水平、10次试验构成均匀试验表,用综合指数对试样进行量化测评,试验结果用SPSS软件进行多项式回归分析,得到了综合指数与诸因素的多项式回归方程,用MATLAB语言对该方程进行单纯性寻优处理,得到的最佳镀液组成为:硫酸镍30g/L、次亚磷酸钠30g/L、糖精0.5g/L、醋酸钠8g/L、柠檬酸钠19g/L、丁二酸7.5g/L、DL-苹果酸9.5g/L,pH值为5.2,综合指数为98.82.经过试验验证的最后结果与计算机优化的结果基本相符.

Computer Optimization of the Technological Conditions for Electroless Nickel

In order to study the best technological conditions of the eletroless nickel, the application of the uniform design and the computer optimization in electroless nickel plating on aluminum were studied. The uniform design was composed with 5 factors, 10 levels and 10 times experiments. The quantification evaluations of the sample with the synthesis index were studied. The test result camed on the polynomial regression analysis with the SPSS software and obtains the polynomial regression equation between synthesis index and the various factors. It also camed on retinitis simplex optimization processing with the MATLAB language to this equation. The optimal formulation of plating liquid were gained,i. e. 30g/L sulfate nickel, 30g/L hypophsphite sodium, 0. Sg/L saccharin, 8g/L acetate sodium, 19g/L citric acid sodium, 7. 5g/L butyric diacid, 9. Sg/L DL-malic acid and the corresponding operation condition is at pH ( 5. 2) , the composite index was 98. 82. The final result after being verified basically aggress with the computer optimized result.
