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 of the
examination of the workability in subsequent manufacturing of such products is the subject of
this paper.
