COPPER corrosionIn the case of a two‐part container for spent nuclear fuel, consisting of an iron‐based inner structure with a copper coating, the potential perforation of copper through minor damage may result in intensive galvanic corrosion between copper and steel. The present...
With the decrease in pH value from 6 to 2.4, the corrosion rate of copper–drawn steel galvanic couple(Cu–Fe GC) obviously increased in the simulated solution of acidic red soil. The electric field formed by the Cu–Fe GC changes the direction of ion migration between the copper and ...
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 ...

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 ...
Copper lines were bridged after corrosion. The corrosion by-product can be removed by means of solvent cleaning. The mechanism and the prevention of this type of light-induced corrosion are reported in this paper. 展开 关键词: chemical mechanical polishing copper corrosion integrated circuit ...
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...
The galvanic currents flowing between couples consisting of two of the corrosion-resistant materials were very small. The galvanic corrosion rate of carbon steel, when connected to one of the other materials, was dependent upon the cathodic-polarisation characteristics of the noble-material surface ...
Atmospheric Corrosion of Laminar Composites Consisting of Copper on Stainless Steel Atmospheric corrosion of laminar composites consisting of copper on stainless steels has been studied through direct exposure of copper-clad ferritic and austenitic stainless steels to provide information on galvanic effects at...
