ABSTRACT:
A method of producing coated powder material is provided. In the method, molten metal or metal alloy is caused to fall in a stream (3) and is then atomized into a spray. A liquid or solid material of different composition is introduced and caused to contact the stream or spray so that a coating is formed over all or part of the surface of the atomized droplets. The coating may be the introduced material or a reaction product.
