The spray casting of metal wherein an atomized spray of metal droplets is caused to be deposited upon a moving metallic foil substrate. The metallic foil substrate is maintained under tension as it passes in a position to receive the deposit such that thermal distortion is eliminated without causing tensile failure. In the second embodiment, the leading edge of the spray is positioned such that it does not contact the foil whereby the low mass density thereof does not contribute to deposit helping to eliminate bottom porosity.

Production of spray cast strip

The apparatus and method for spray casting a spray of molten metal on a moving substrate. The leading edge of the spray pattern is deflected away from or into the spray pattern to eliminate the cooler and less dense particles of the leading edge from contacting the substrate. The deflector preferably has a surface of non-wetting material to prevent the build up of material thereon.
