What is galvanized iron?
The galvanization technique has been present since the 19th century, many are the buildings and structures that are channeled with said material for the conduction of both residual and potable water. The galvanization process consists of coating one metal with another, it is carried out in materials such as steel or iron. The most common galvanizing consists in depositing a layer of zinc (Zn) on iron (Fe). The purpose of such a process is to help resist oxidation and corrosion that can cause moisture and environmental contamination to the coated material. There are several processes to perform the zinc coating, the main ones are hot galvanizing which consists of immersing the material in a melted zinc crucible at a temperature of 450 ° C. Another common procedure for galvanizing iron or steel is the so-called electrolytic galvanizing, this process uses several elements: Power supply for voltage transformation, a solution of metallic salts called electrolyte and finally the an...
