The final stage of copper CMP requires the simultaneous polishing of copper and the barrier metal, where the metals are prone to galvanic corrosion due to exposure to slurry. In this study, the extent of galvanic corrosion between copper and tantalum was estimated using electrochemical polarization ...

However, this result did not allow for a clear conclusion regarding differences in corrosion. This study did not find galvanic corrosion of the welded stainless steel and carbon steel. 展开 会议名称: Mechanics of Structures and Materials: Advancements and Challenges, Volume 1: Proceedings of the ...
The corrosion behaviors of copper and copper/titanium galvanic couple (GC) in seawater were studied by electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques in conjunction with scanning electron microscopy (SEM) method. The results show that the corrosion process of copp...

For example, zinc will corrode in saltwater extremely quickly when in contact with platinum, but 304 stainless steel in contact with 316 stainless steel will have little effect on each other. Here's an example of galvanic corrosion between carbon steel and aluminum in sea water:...
(small anodic or active surface area) with the metals separated by wool felt which eventually failed. In 1984, it was closed to the public due to significant corrosion of the cast-iron frame. It was rebuilt using a duplex stainless steel structural frame. Copper alloys and stainless steels ...
Although hot-dip galvanized coatings offer envelope protection for steel, zinc contained in the coating will also safeguard the steel cathodically in case the coating is destroyed and the bare steel exposed. Preventing Corrosion in Galvanized Steel The galvanized coating’s rate of consumption will be...
