To reduce deterioration by making a metal anode with a postive fee. This has low voltage present and keeps the environment electrochemically passive. It had been conceived in th 1950s and it is appropriate preventing deterioration.
lowering of deterioration, achieved by making a metal framework anode (positive electrode) with a reduced voltage direct current so that it attains and maintains an electrochemically passive state in a specific environment. Developed in 1950s, anodic defense is more suitable than cathodic protection for certain metals such as stainless steels especially in exceedingly corrosive environments, like in the management and storage space of concentrated sulfuric (sulphuric) acid. This process, but requires careful tracking and control usually it may alternatively accelerate the deterioration process.
