In 1836, Sorel in France took out the first of numerous patents for a process of coating steel by dipping it in molten zinc after first cleaning it. He provided the process with its name ‘galvanizing’.
Webb25 maj 2024 · The surface of the steel must be smooth and free of major defects. Cleaning steel is an essential step before the regalvanizing process, but it is not the only preparator step. Next, the steel may be sent through a “pickling” process. This isn’t a treatment that is only used for regalvanizing steel. Much steel is pickled before its first ... WebbHot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 °C (840 °F).
