Introduction Galvanizing could be a method of coating iron or steel with metallic element so as to supply bigger protection against corrosion for the iron or steel base. the method of galvanic plate iron was developed at the same time in France and European country in 1837. each of those strategies utilized a "hot dipping" method to coat plate iron with metallic element. Like tinplate, early galvanized metals were hand swaybacked. nowadays most Fe and steel is electroplated. The following square measure the foremost common strategies for applying protecting coatings of metallic element to iron and steel: Hot-dip Galvanizing : The immersion of iron or steel in liquified metallic element, once the surface of the bottom metal has been properly clean. This method offers a comparatively thick coating of metallic element that freezes into a crystalline surface pattern called spangles. During the method, a multiple bedded structure of iron- or steel-zinc alloys is created between ...
