surface alloying

surface alloying

[′sər·fəs ′al‚ȯi·iŋ]
(metallurgy)
Deposition and metallurgical bonding of additional metals or alloys on the surfaces of ferrous or nonferrous metals; such additional materials become an integral part of the total mass, as distinguished from coatings which are bonded mechanically.

The metal powder then melts and gives a dense coating, which further creates a strong bond with the metal surface or work piece by the means of diffusion and surface alloying. In a powder welding assembly, the hopper is attached to the flame torch where the metal powder is fed.
