HERSTELLUNG VON SCHICHTEN DURCH ZERSTÄUBUNG

摘要

A method and apparatus for the production of a deposit such as a bar (1) is provided. The deposit has a longitudinal outer surface (2) and a front face deposition surface (3). The spray deposition comprises atomized droplets produced by outer and inner sprays (4 and 5). The outer and inner sprays (4 and 5) are both directed such that, during deposition, a substantial proportion of droplets from both sprays are deposited on the front face (3) of the forming deposit. The inner spray (5) has a higher gas to metal ratio than the outer spray allowing an increase of both deposition and final product yield.
