Can't successfully scale-up Electrodeposition from good lab results

We are studying a new Ni alloy steels applied by electrodeposition, we test on a line of 2 liters of solution and get good results, but when we use a pilot line 250 liters of solution, as if burnt out parts at the points where they contact with the wires hanging system. In line minilinea pilot and we are using the same conditions, rectifier etc, just change the dimensions. Could help me understand this situation.

If I read your question correctly, you need to go to bigger wire gauge for your hangers. Try it, it might solve the problem.

Hello,

In a small scale, the electrolyte volumes are low with less current requirement. When it is scaled-up, electrolyte volume is more and there is concentration gradient problem. You may have to go for cathode rod movement or air agitation or solution circulation to obviate this problem. Anode and cathode area ratio must be adjusted. Thicker cables/busbars to carry the current is also to be taken care of.

Good luck!
