I have a problem in relation to the fracture of a chrome/plated brass tap/faucet fitting. Within the pipe there is the presence of a green corrosion product (quite alot not just a patina) also the chrome/plated brass faucet has a screw thread which is connected to a copper pipe using a brass connector type fitting. Will galvanic corrosion occur between the chrome/nickel plated screwthread and the brass connector? or is this possibly due to over chlorination of the water? Regards

Materialman: The green corrosion product may be copper oxide or it could be chromium chloride. Re the galvanic question, galvanic corrosion should not occur between the two couples unless immersed in water, which it doesn't appear to be, based on your explanation. However, there could be a small active galvanic current between the brass faucet and the hard chrome plating. Hope this helps! David Hendrix The Hendrix Group Inc.
