Copper Plating Troubleshooting

 

Problem

Cause

Remedy

No deposit

No current (or gassing from part)

Check all electrics

 

Pitted Plate and Orange Peel effect

 

Impurities in solution

Plate a dummy for 30 mins. If no improvement, filter solution through activated charcoal placed into a coffee filter, then replace the Brighteners

Rough Plate

 

1. Amps too high

 

2. suspended particles in solution 3. pH too high or low

1.   Reduce current

2. 2. Filter solution through a coffee filter (No charcoal)

3. Dump solution and   make a new batch

Check anode bags are not torn etc.

Dark deposits (esp. on low spots)

Zinc, lead etc. in solution

Plate a dummy for 30 minutes.

'Burnt' Plate

Too much current

Reduce current, check solution temperature and reduce if needed.

Cloudy deposits on the plate

 

1.   Poor cleaning/rinsing

2. Organic contamination 3.   High temperature

4.   Low agitation

1.   Improve cleaning/rinsing

2. Filter   solution through activated charcoal placed into a coffee filter, then replace the Brighteners

3.   Adjust temperature 4.   Improve air agitation

 

Dull plate

1.     Too   much amperage 2.   Part not buffed enough 3.   Brighteners Exhausted

1. Reduce amperage 2.   Buff and re polish

3.   Add Copper Brightener B

Plate Peels or Blisters off

1.   Current too great

2. Surface too hot when buffed

3. Poor                    surface preparation

4.   Plated onto steel

1.   Reduce amperage

2.   Reduce     pressure   on Buffing

        wheel

3.   Improve technique

4. Prime steel with nickel before copper plating

Plate peels or blisters off when applied to nickel base

1.   Nickel has oxidized

2.   Insufficient cleaning

3. Too much power whilst plating  

1. Prior to plating swab nickel   base with battery acid, then rinse.

2.   Reappraise   cleaning methods

- use Soft Scrub etc

3.     Reduce amperage.

4. Reverse the current for 60 seconds to 'etch' the   surface of the part.
