Difference between hot-dip galvanizing and electro galvanization

1. Noble Metal Coating Presents Hot-dip Galvanizing Vs Electro Galvanization: What's The Difference The Difference In The Process Of Applying The Zinc Layer Hot-dip galvanization & electro galvanization technique both focuses on the application of strong zinc layer on the metallic substances, but in a different way the layer of protective zinc coat is applied by using a current of electricity. Formation Of The Zinc Layer When the zinc layer is formed on the metallic surfaces by using the electro-galvanized technique, the thickness of the zinc layer is about 3 to 6 microns. whereas in hot-dip technique a thickness is 50 microns The Cleaning Process In hot-dip galvanization process The metallic surfaces are cleaned thoroughly in alkaline solution and water rinsing. Whereas if you wish to go with an electro galvanization process, then there is no requirement for any sort of stringent cleaning method. The Life Expectancy Of The Products Generally, the layer formed by electro galvanization is extremely thin, hence the life expectancy of the layer is low (just several years) as compared to the hot-dip galvanization process. Different Applications Of The Galvanization Process Generally, the hot-dip galvanization technique is used for metallic substances of all sizes, whereas electro-galvanization is suitable exclusively for smaller components.
