Nickel sulfate 80 g/l 50 - 100 g/l
70320 D Conductor 80 g./L 50 - 100 g./L
70320 A complexing agent 100 ml./L 80 - 120 ml./L
70320 B Regulator 10 ml./L 5 - 20 ml./L
pH 6.2 5 - 7
Temperature 55°C 50 - 60°C
Time 1.5 minutes 1~3 minutes
Anode carbon plate
Anode to cathode ratio 1 : 1 ~ 1 : 2
Stirring mechanical movement
continuous filtration
Note: When preparing the solution, adjust the pH to 6.2 with phosphoric acid
Little black deposits are produced at high pH.
Use KOH to raise the pH and phosphoric acid to lower the pH.
operating conditions
Sn-Co plating usually requires a layer of bright nickel as a base, and the process flow is as follows:
Bright Nickel – Restoration – Rinse – Rinse –70320 gun black– restore – rinse – rinse
-- Finishing -- Rinsing -- Rinsing -- Drying
Post-processing:Mainly to increase corrosion resistance.
Chromic acid: 50 g/L, soak for 30 seconds at room temperature.
