Melt-phase spray-coating methods and apparatus for melt-phase spray-coating of a plain-carbon steel slab (79) of selected carbon content in the range of .02 % C to .12 % C, with corrosion-resistant metal selected to have thermal expansion and contraction values compatible with those of the steel selected for such slab (79), for production of composite-metal product. Atomized molten metal of selected size is interspersed with solid particulate of selected particulate size to enable substantially uniform spray-coating of a prepared slab surface. Control of the temperature of slab (79), atomized metal and particulate metal, and hot reduction processing facilitate desired metal diffusion, desired bonding with the steel substrate (79) at the interface and adhesion during cooling and thickness reduction. |
