Help! Gold plating over copper alloy, blister/flaking?
September 4, 2010
Q. Does anyone recognize the issue here? or what may cause this problem with the plating. The finish has many of these spots that flakes/blisters.
It's gold plating over machined copper alloy (I believe it has a nickel underplating).
Possibly improper cleaning? or trapped salts in the base metal pores?
Any ideas would be highly appreciated.
