Localized corrosion in copper tubes and the effect of anti-tarnishing pretreatment

Localized corrosion with an "ant nest" morphology was studied on untreated ad tarnish resistant treated Cu tubes. The treated tubes suffered worse corrosion, which is believed to be the result of the formation of large cathodic areas by the treatment leaving anode areas to be attacked. Thi...

Summary:Localized corrosion with an "ant nest" morphology was studied on untreated ad tarnish resistant treated Cu tubes. The treated tubes suffered worse corrosion, which is believed to be the result of the formation of large cathodic areas by the treatment leaving anode areas to be attacked. Thin water layers appear to aggravate the problem. Formic acid is believed to be formed by the reaction and causes the problem. Photomicrographs. 6 ref.--J.C.J.
