metal contactssilverIn this work, commercial silver metal contacts welded on top of silver plated brass or brass substrates have been exposed to air rich in NaCl. Scanning electron microscopy and energy dispersive analysis of the exposed contact surfaces were performed to identify the corrosion by-...
Two complementary models to describe the long-term corrosion of silver-copper coins, based on potential rate laws for smooth corrosion and those combined with diffusive law, for gross corrosion, are proposed. Theoretical kinetics can be tested using signatures of copper and silver corrosion products ...

Ni or Co in the intermediate layer is a base metal for introducing P into the intermediate layer and moreover has the operation of preventing the phenomenon that Cu diffuses into the plating and is oxidized to increase the contact resistance. The thickness of the intermediate layer is ...
Corrosion of precious-metal-plated copper alloys after exposure to a mixed flowing gas environment was studied. Six copper alloys used in electronic connectors were selected for study. All alloys were plated with a nickel underplate, followed by a precious metal surface plating of gold or gold-fl...

For noble metal alloys such as Ag–Au, IGSCC is a consequence of dealloying corrosion, forming a nanoporous gold layer that is believed to have the ability to transmit cracks into grain boundaries in un-dealloyed parent phase via a pure mechanical process. Here using atomic-scale techniques ...
The effects of temperature on corrosion resistance of Silver–Cobalt oxide and Titanium Dioxide (Ag/Co3O4/TiO2) nanocomposite coated AISI 1020 in a high-temperature environment was investigated. The Ag, Co3O4 and TiO2 nanoparticles were individually prod
