Barrel zinc-nickel: how do you control pH drift?

Our barrel zinc-nickel bath drifts upward during the shift and we correct it manually. Results are acceptable but not stable.

How do you control pH in production?

  • Automatic dosing and setpoint
  • Frequency of analysis
  • Effect of drag-in and rinse water
  • Relationship between pH and nickel content

We are a small line, so a simple control strategy is more useful than a fully automated system.
