WebWhereas, the other methods of protecting a metal are alloying, galvanizing, electroplating, etc. Alloying. An alloy is a mixture of two or more metals. Alloying is a process where metals like iron or steel are mixed with a less reactive metal like chromium, magnesium, etc for protection against corrosion and to create non-rusting alloys. WebTank cars, vessels, bridges, ship-hulls, fabricated steel products, refrigerators are flame-sprayed. This method produces thick coats and any metal can be spray-coated. iii.
