MAKING COMPOSITE METAL DEPOSIT BY SPRAY CASTING

A laminated composite metal deposit is made by providing a first metal stream a second metal stream and a substrate, atomising the two streams to form first and second sprays of hot metal particles by subjecting the streams to relatively cold gas directed at the same stream and depositing the sprays...

More Information
Summary:A laminated composite metal deposit is made by providing a first metal stream a second metal stream and a substrate, atomising the two streams to form first and second sprays of hot metal particles by subjecting the streams to relatively cold gas directed at the same stream and depositing the sprays alternately on the substrate. The two streams may be different alloys of the same base metal, e.g., aluminium, and either may contain fibres, whiskers or particles of refractory material.
