A device for gas atomizing a liquid stream, such as a stream of molten metal or metal alloy, has an atomizing device including, for example, an annular opening for receiving the stream. The atomizing device is arranged for applying atomizing gas to the stream so as to form a spray of atomized particles. At least a part of the atomizing gas, and preferably all, is applied by means movable relative to the stream whereby movement is imparted to the spray. This movement leads to improved uniformity or control of deposition.

Apparatus for gas atomising a liquid stream, such as a stream of molten metal or metal alloy, and for controlling the mass distribution of a layer deposition from the atomised stream, the combination comprising: an atomising device; a plenum chamber forming a part of the atomising device and defining an opening through which the stream may be teemed; atomising means communicating with the plenum chamber for forming an atomising gas flow field of predetermined geometry which atomises the stream into a spray of droplets; and means for moving the atomising device angularly about an axis and relative to the stream whereby the application of angular movement about said axis may impart an oscillation to the gas flow field and thereby to the spray with the geometry of the atomising gas flow field remaining substantially constant.
