| Abstract: |
| 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. |
