Abstract: A method and apparatus for the production of spray deposited ingot, disc or bar is provided it which a spray of gas atomized molten metal or metal alloy particles generated with an atomizing device is directed onto a collector. The collector is rotated about an axis of rotation and a controlled amount of heat is extracted from the atomized particles in flight and on deposition. In order to maintain a substantially constant distance between the atomizing device and the surface of the deposited metal or metal alloy there is relative movement between the atomizing device and the collector. The spray is directed so that the main axis of the spray and the axis of rotation of the collector are inclined at an angle to one another; and the spray is oscillated so that the main axis of the spray oscillates relative to the axis of rotation of the collector. By the method of the invention the shape of deposit is not dependent on the shape or physical containment of the collector, for example, a mould as used in a casting process is not required.
