Minimizing trichrome formation in hard chrome plating

2005

Hi.
I would like to know how I can reduce the production of tri chrome during hard chrome plating. We plate over hardened base metal. We get high tri chrome in the bath which forms tree like structure on the frame and musks over the work piece.
This not only wastes chrome but also present a maintenance problem.

Vitali,
1.Increase the anode area.
2.Electrolise the bath with large anode area and minimum cathose area(U can use a sigle Mild steel rod as cathode.)
To keep CrIII at minimum level for ever,I would suggest you to do this every day for 15 minutes bfore starting the production.
good luck

Maintain anode : cathode ratio as 2 : 1 in normal working. Electrolyse the bath regularly with a anode : cathode ratio of 10 : 1.

If usually working i.d with samll anode area or if cathode area is more than anode area electrolyse bath at 30:1 anode to cathode ratio or 600 amps/sq.ft.

good luck
