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.
