Abstract
A process for applying a metal coating 11 to a metal strip substrate 2 by preheating the casting surface in a non-oxidizing atmosphere and maintaining a casting surface temperature T.sub.s below the solidus temperature of the metal coating material, passing the casting surface through a melt pool 9 of the metal coating material at a pool temperature at least 25.degree. C. in excess of its melting temperature to deposit a melt layer 21 at a casting temperature T.sub.c, and simultaneously rapidly cooling the metal strip substrate from the back surface to solidify the melt layer to an adherent solid coating, wherein the surface temperature T.sub.s is less than about 20 percent (in .degree.K.) below the casting temperature T.sub.c. The process is particularly useful when coating metal strip with an alloy of limited solubility metals.
