Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of hot, molten zinc. See more The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to … See more Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item. In the case of automobile bodies, where additional decorative coatings of paint … See more This is the most common use for galvanized metal, and hundreds of thousands of tons of steel products are galvanized annually … See more • Aluminized steel • Cathodic protection • Corrugated galvanized iron • Galvanic corrosion See more The process is named after the Italian physician, physicist, biologist and philosopher Luigi Galvani (9 September 1737 – 4 December 1798). The earliest known example of galvanized iron was encountered by Europeans on 17th-century Indian … See more Galvanized steel can last for many decades if other supplementary measures are maintained, such as paint coatings and additional See more In the early 20th century, galvanized piping replaced previously-used cast iron and lead in cold-water plumbing. Typically, galvanized piping rusts from the inside out, building up layers … See more WebThe main restriction in the specification for repairing newly galvanized material is the size of the area which is outlined in the product galvanizing specifications: ASTM A123.
