ABSTRACT:
Metal corrosion which occurs under conditions of use is mitigated and controlled by a sacrificial anode device which can be easily attached to, and detached from the corrosion-prone object. In ambient applications, the anode and cathode components of the device may be distinct metallic elements which may be alloys, or layers of alloys, and which are configured so as to optimize the interface surface area between the anode and cathode, while being sufficiently compact to be placed essentially in any corrosion-prone location. In extremely wet applications, such as underwater, or in water circulating or storage systems, the anode may be an effectively configured block of metal, and the cathode will be the water constituent of the environment in question. The optimized anode/cathode interface area provides increased operating life for the device, reduces material waste, and strengthens the structure of the device.
