White Corrosion Points on Brass Ni/Cr Plated Parts


Dear Sir I work for a OEM faucet company. The parts are brass Ni/Cr plated for service condition 2.

The goods that we have shipped by sea have become white with corrosion points that where detected when they arrived at the customer. We make quite often the corrodkote test (4 hours), modified salt spray test (acetic acid) (24 hours). The parts passed without any points of corrosion, but if we make a climatic test (humidity 95% at 38  C) we have white corrosion points.

I would be grateful to know about your experiences on this subject

If you can't reduce porosity of your finish, you may be able to preserve the parts for shipping by dipping is some sort of wax.

Even though automobile finishes will last a lifetime, they still coat the outsides when they are being shipped overseas.
