Abstract
One of the advantages of atomization is to be eazy for making spherical metal powders. This paper presents three examples of spherical atomized powders developed; bronze powders for sintered metal filters and dry bearings, copper-lead alloy powders for steel-backed bearings and self-fluxing alloy powders for thermal spraying.
First, the improvements on the air-and gas-atomization equipments used for the production of spherical powders are described, and then, the manufacturing process, powder characteristics in each application and the problems in the mass production of metal powders by atomization are reviewed.
