The anodes can be either simple copper slabs or titanium or steel baskets filled with copper nuggets or balls. [6] The anodes may be placed in anode bags, which are typically made of polypropylene or another fabric and are used to contain insoluble particles that flake off the anode and prevent them from contaminating the plating bath.

Anodic protection (AP) otherwise referred to as Anodic Control is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell and controlling the electrode potential in a zone where the metal is passive.
Iron or carbon steel metal exfoliates when oxidized under neutral or alkaline micro-electrolytic conditions; i.e., the iron oxide (actually ferric hydroxide or hydrated iron oxide, also known as rust) forms by anoxic anodic pits and large cathodic surface, these pits concentrate anions such as sulfate and chloride accelerating the underlying ...
After three years, the anodes simply need a new coat of catalysts made from affordable, earth-abundant elements to make them as good as new, lasting for decades. “This breakthrough is the crux of Equatic’s ability to scale to gigaton volumes and has global implications,” emphasized Edward Sanders, chief operating officer at Equatic.
When the anode is made of the metal that is intended for coating onto the cathode, the opposite reaction may occur at the anode, turning it into dissolved cations. For example, copper would be oxidized at the anode to Cu 2+ by losing two electrons. In this case, the rate at which the anode is dissolved will equal the rate at which the cathode ...

A plate, usually called anode in Britain, is a type of electrode that forms part of a vacuum tube. [1] It is usually made of sheet metal, connected to a wire which passes through the glass envelope of the tube to a terminal in the base of the tube, where it is connected to the external circuit.
