<p>A method of forming a deposit in which a spray of gas atomised molten metal or metal alloy is generated and directed at a substrate. The substrate is rotated about an axis of rotation and a controlled amount of heat is extracted from the molten metal or metal alloy in flight and/or on deposition. The spray is oscillated relative to the substrate, preferably along the axis of the substrate. With continuous production techniques involving a single pass, base porosity can be considerably reduced and in the formation of thicker deposits of discrete length base porosity can be minimised and reciprocation lines can be eliminated or reduced in intensity.</p> |
