What is electogalvanization?
Electrogalization is a process used in metal processing to prevent corrosion. Zinc electropping, process process or galvanization, adheres to the zinc layer to the surface of steel to inhibit rust and corrosion. Zinc is not a normal corrosion, so this metal plating protects steel that lies under the plating. Electric current is introduced to this setting, while the zinc anode is connected to the positive side of the energy source, while the steel to be galvanized is connected to the negative side of the energy source. By attaching the power supply in this way, the positively charged zinc ions are attracted to a negatively charged steel. This process is used as a method of corrosion prevention for various products produced. Galvanized nails, bolts, cabling and pipes are common examples of products that are used by electrogalvanization. In addition, the automotive industry has widely used the electrogalization process to protect the body, frames and other components.
Use of electrogalization as a corrosion layer is common for products that are used in an environment where they would be exposed to weather conditions or corrosive elements. Products made of electrogalvanized steel remain useful long after the same product of conventional steel would be reduced to rust, due to the properties of rust prevention of electrogalization. From wire fences and electogalvanized steel gates to highway signs and household appliances, electrogalization is used almost anywhere is the desired long -lasting metal product.
By adding chemical components to zinc solution and salt solution used in the electrical process, other advantage is to obtain. Car manufacturers commonly use a technique called prerephosfting to improve the surface adhesion of paint on the electogalvanized part. By adding phosphate salts or other chemicals to an electogalvanization solution, they can become different benefits-like is fromAdhesive adhesion of paint, lubrication or color-because chemicals are built into the electropated zinc layer.
Electrogalization is not the same process as zinc. The electrogalization process requires the use of electricity to create a zinc layer on a steel conductor. This process is more permanent than zinc plating processes, such as immersion of hot, because the zinc actually adheres to steel at the molecular level, rather than being just a coating added to the steel. This is an important resolution, but the wrong identification of zinc plating as an electrogalization is quite common.
