57 A process of producing a metal body comprises atomising a source of molten metal and directing the atomised molten metal particles, as a spray, onto a cooler substrate, on which the molten metal particles splat and build up to form a deposit, characterised by controlling the spray conditions so that the whole, or most, of the surface of the deposit is molten throughout the process.

Aufspritzen (Metall) spray-metallizing
http://www.muhendislikbilgileri.com/FileUpload/ks256985/File...

This invention relates to a method and apparatus for coating a corrodible base metal, on one or both sides, with another metal which is molten. More particularly, the invention relates to a method and apparatus for spray metallizing a coating of metal onto one side of the metal, using an electric arc.

A number of processes are known for the production of sheet steel which is galvanized on one side. These include such conventional methods as the continuous passage of sheet metal through a bath of molten metal, and continuous thermal spraying. Commercial galvanized sheet in which zinc is coated on both sides is not generally acceptable for use in automobile body construction because of complications arising from the adherence of zinc to the tips of welding electrodes in resistance welding processes. Again, while it is desirable to have the zinc covering on interior surfaces where its protective qualities are most needed, it is desirable to leave the exterior surfaces uncoated to promote the adherence of paint or other surface finishes.

In the case of the thermal spraying process, the material being sprayed, in this case zinc, is supplied to "pot guns" in bulk form and heated to a temperature of approximately 426-482°C, and atomized with a propellant such as air and sprayed onto the surface to be coated. In another version of this process, wire or powder is fed into an oxy-fueled flame which melts it and air atomizes and propels it onto the surface to be coated.

Electric arc metallizing which utilzes two metal wires fed to an electric arc, is described in US-A-3,546,415, herein incorporated by reference.
