What is anodic protection?

Anodic protection is a method used to prevent corrosion. This method is most often used in a highly corrosive environment to protect metal submerged in a solution with unusually acidic or basic properties. Anodic protection differs from cathodic protection, other techniques used to prevent corrosion in metal devices and structures. In anodic protection, electric current is used to create a protective oxidized layer on a protected base, often known as a substrate. This process is most often used in industrial production. Cathodic protection differs from anodic techniques because cathodic protection uses a metal rod called sacrificial cathode to corrodes instead of protected metal. This technique is usually used in water, while anodic protection methods are used in a more corrosive environment.

commonly used to protect metal in solutions with unusually high or low potential hydrogen levels (pH) that indicate the acidic or basic nature of the solution is for steel the bestAnodic protection uses more. This technique can usually be found in factories that work with high or low pH solution, especially sulfuric acid, phosphoric acid or chrome acid. Other less used substrate materials that can benefit from anodic protection include magnesium, titanium and zinc.

Anodic protection works by creating a protective layer called anodic film on the basic metal. Anodic film is a controlled oxidized layer created on metal using a controlled electric current that can be used to increase and reduce the thickness of anodic film. This film acts as a barrier against the corrosive nature of its environment. In industrial applications involving highly corrosive materials, the constantly maintained current balance maintains metal containers in corroding. Sensors monitor the current level in solution and in protected metal that acts as an anode, and if the monitor feels that the interestOutside the current dropped below safe levels, the system will alert the technique.

6 When dyeing metal with anodization instead of oxidation of surface metal on a protected substrate, the elodization process is glued to the colored metal, which has been dissolved into the substrate metal solution. The result is a color coating throughout the metal object.
