Cathodic Protection is a Method Used to Control Corrosion What is cathodic protection meaning for? Generally, Cathodic Protection (CP) is an electrochemical (half electrical and half chemical) method used to control corrosion of buried or submerged metallic structures. Cathodic Protection is a method used to control corrosion. It prevents corrosion by making the protected structure a cathode by installing a more anodic metal (sacrificial or galvanic) anode or a metallic (impressed current) anode connected to a Direct Current (

Why Dimensionally Stable Anodes(DSAs) Are Used for Zinc Electrowinning? Zinc electrowinning is one of the basic processes of the electrochemical industry. Lead-silver anodes have been used in zinc production for years. Although these electrodes have the lowest current efficiency for zinc deposition and higher electrical energy consumption when compared to pure lead anodes, they are widely used because of their high corrosion stability in acid (H2SO4) solution and because of the higher purity of the zinc cathodic deposits. In se

How Dimensionally Stable Anode(DSA) is Used in Hydrogen Production? Carbon emission from carbon-based fuels causes environmental problems, while hydrogen is regarded as a new energy source to replace fossil fuels. The production and storage of hydrogen have become essential technologies recently. Electrolysis of water using electricity or sunlight is the method that is being used for the environmentally benign production of hydrogen. However, hydrogen production through electrolysis is hindered by the slow oxygen evolution reaction

Detailed Explanation About Impressed Current Anodes for Buried Concrete Structures Galvanic Anodes For buried concrete structures, traditional galvanic anodes based on zinc or magnesium may be used. The required minimum net mass of the anodes is determined from the total current requirement, anode alloy capacity, design life and anode utilization factor. The size and number of anodes is also determined from the anode current output, which in turn is based on anode shape, soil resistivity and anode operating potential. For high-res
