Common Problems During Plating

During the plating we face many problems during process after many precautions , some are here :

1.  PITTING : 

Pitting come due to hydrogen attack on the base metal or coated metal during acid pickling/Plating in the acid bath .

2.  ROUGHNESS : 

Roughness means rough deposit which come due to foreign particles deposit with metal or coarse deposit due to excess current .

3.  PEEL OFF : 

Peel off  means removing of coated metal due to improper cleaning of base metal etc .

4.  LOW THICKNESS : Less coating

5. LESS SALT SPRAY LIFE OR CORROSION RESISTANCE : Poor corrosion resistance due to poor plating process or wrong process .
