Generation and forming of spray-formed flat products

Cylindrical or billet-like semi-finished materials are already manufactured industrially by means of spray forming. Examples of end products produced from such materials are cylinder liners and welding electrodes. The advantages of spray forming, exploited during the production of the raw materials for these components, are the homogeneity of the produced material, the high cooling speeds in the spray cone, the flexibility of the spray-forming facilities and the extended alloying capabilities. For flat products, however, a process-determined porosity, which appears negligible with large volume products, as well as problems with the production of a geometry suitable for subsequent treatment obstruct the commercial use of the potentials of spray forming in the field of flat or sheet metals. The production of flat and sheet metals and the examination of the workability in subsequent manufacturing of such products is the subject of this paper. Article Outline
