Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the … Ver mais Cathodic protection was first described by Sir Humphry Davy in a series of papers presented to the Royal Society in London in 1824. The first application was to HMS Samarang in 1824. Sacrificial anodes made from Ver mais Galvanic In the application of passive cathodic protection, a galvanic anode, a piece of a more electrochemically "active" metal (more negative electrode potential), is attached to the vulnerable metal surface where it is exposed … Ver mais Production of hydrogen A side effect of improperly applied cathodic protection is the production of atomic hydrogen, leading to its absorption in the protected metal and subsequent hydrogen embrittlement of welds and materials with high … Ver mais • Anodic protection • Cathodic modification • Corrosion engineering • Redox • Wetting voltage Ver mais Hot water tank / Water heater This technology is also used to protect water heaters.
