A zinc anode is a type of sacrificial electrode that is used to protect metal structures from corrosion. It consists of a solid piece of zinc, often in the form of a rod or plate, which is connected to the metal structure being protected. When immersed in an electrolyte, such as water or soil, the zinc anode undergoes a process called galvanic corrosion. The zinc gradually corrodes instead of the metal structure, sacrificing itself to protect it. This electrochemical process helps to prevent rust and deterioration, making zinc anodes an essential component in various industries, including marine, oil and gas, and construction. 🧪⚡️
