  • What is the Process for Coating Metal with Zinc ...

    The process for coating metal like iron or steel with a thin zinc layer is known as galvanization. The zinc layer serves to protect the metal from rusting. There are three different processes that can be used for galvanization. The two less-common processes are electrodeposition and electrochemical, while the one used the most often is hot dip galvanization.

  • Galvanization Process - ScienceStruck

    Jun 06, 2019· The zinc compound is exposed to an electric current, thereby, making the zinc ions positively charged. These ions then establish a more secure bond with the primary metal, thus providing a somewhat stronger tensile strength. However, this process tends to be inefficient for materials which are constantly exposed to elements like salt water.

    Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.
