Localized corrosion of Cu and Al thin films exposed to aqueous NaCl solutions was studied using liquid cell transmission electron microscopy (LCTEM). We demonstrate that potentiostatic control can be used to initiate pitting and that local compositional changes, due to focused ion beam implantation of Au(+) ions, can modify the corrosion susceptibility of Al films.

The proposed long-term management plan for used nuclear fuel is to isolate it within a multiple-barrier system underground in deep geological repository (DGR). In the Canadian design, bundles will be sealed copper-coated carbon steel containers, encased blocks of bentonite clay, emplaced approximately 500–800 m below ground, and surrounded by gapfill material. A laboratory experimental campaign...

This study presents an analytical investigation and electrochemical conservation treatment for a group of four copper alloy artifacts excavated from the archaeological cemetery that was located on site Queen Alia International Airport, Jordan. The chemical analyses internal alloys showed bracelet spatula were made quaternary copper–zinc–tin–lead alloy, copper–silver–zinc copper–tin, bronze allo...

Copper/aluminum alloys are largely utilized in odontological restorations because they are less expensive than gold or platinum. However, tarnishing and important corrosion in intrabuccal prostheses made with copper/aluminum alloys after 28 days of use have been reported. Several kinds of food and beverage may attack and corrode these alloys. Copper is an essential component of several importan...

Limestone basements holding bronzes or other copper alloys artefacts such as sculptures, decorations and dedicatory inscriptions are frequently met both in modern and ancient monuments. In outdoor conditions, such a combination implies the corrosion products of the copper based alloy, directly exposed to rainwater, will be drained off and migrate through the porous surfaces, forming stains of d...
