Applications
• Cathodic protection:
Cathodic protection is a method of protecting metals from corrosion by applying a protective layer of metal. Sacrificial anodes are often used for cathodic protection of steel structures, such as pipelines and bridges.
•Electroplating:
Electroplating is a process of depositing a layer of metal onto another metal. Sacrificial anodes are often used for electroplating zinc onto other metals, such as steel.
•Solder baths:
anodes are also used in solder baths, which are used to melt solder. The sacrificial anodes help to prevent the solder from oxidizing.
Works
• The way a sacrificial anode works is based on the electrochemical principle of cathodic protection. In this principle, a more active metal (the anode) is connected to a less active metal (the cathode). When an electric current is applied, the anode corrodes and the cathode is protected from corrosion. The anode corrodes because it is more easily oxidized than the cathode. When the anode corrodes, it releases electrons into the electrolyte. These electrons flow to the cathode, where they prevent the cathode from corroding.
• The amount of corrosion that occurs on the anode depends on the size of the anode, the current density, and the electrolyte. The larger the anode, the slower it will corrode. The higher the current density, the faster the anode will corrode. The more corrosive the electrolyte, the faster the anode will corrode.
• Sacrificial Anodes are sacrificial metal elements strategically placed on structures to prevent corrosion by sacrificing themselves to protect the more valuable metal. Regular inspection and replacement of these anodes are essential for maintaining their effectiveness in corrosion prevention.
