Can you supply a maintenance schedule for our hard chromium plating baths?

This is a good question! It is always nice to find people that are concerned about regular scheduled maintenance of their plating baths. Here is a general maintenance schedule that is a good place to start. As you can see, this schedule is not rocket science by any means but just plain common sense. You may want to modify it to fit your specific requirements.
Clean electrical system components
Adjust liquid level of tank
Check temperature of bath
Check overall concentration with hydrometer
Clean anodes with wire brush and alkaline cleaning solution
Check rectifier cables and bus bars
Analyze for chromic acid
Analyze for sulfate
Analyze for trivalent chromium
Analyze for iron and copper as required
Clean the tank
Inspect and clean rectifiers
Check tanks for leaks
Examine lining and heating coils for defects
