Chlorine pitting corrosion of chromium-plated steel cylinders


I am looking for help on a particular technical problem. What is the best possible remedy to stop chlorine pitting corrosion of hard chromium plating on steel cylinders continually exposed to the outside atmosphere.Current plating thickness is approximately .001".The only reference which I have found is that while heavier coatings (.002"-.003") of hard chromium will help slow down corrosion, it is no guarantee that pitting corrosion will not occur.

Thanks Very Much,

One of the simplest and economic remedies is to ask your chrome plater to apply an underlay of 0.001-2" thick nickel before chrome plating. If not possible to send out for replate, find a shop that does brush plating in this site (also known as electrochemical metallizing). He can rework your cylinders on-site and almost with no limitation of size.

Good luck.
