| Abstract: |
| To improve the corrosion resistance of electroless Ni-P alloy, used Q235 steel as substrates, the effect of process parameters on the corrosion resistance of the nickel-plating was studied in the acidic solution at middle temperature by the orthogonal experimental method. By the range analysis, the best conditions were determined:process for the best prescription: molar ratio of Nj2+ and H2P02 - is 0. 48 ; compound complexing agent of lactic acid is 15mL/L; propionic acid is 5mL/L; accelerator NaF is 0.4 g/L; Stabilizer thiourea is Img/L; buffer sodium acetate is 16.5g/L; surfactants lauryl sodium sulfonate is lOmg/L; pH value 5.2; plating time is 2h; heat treatment temperature is 500℃. On the condition, the corrosion current is 2. 166 x 10 -5A and the corrosion resistance is improved. |
