Process parameters optimization for the spray forming of a Cu-6% Zn alloy w
as developed by a combination of mathematical simulation and the factorial
design method (FDM). The finite difference method was used for the mathemat
ical simulation of the atomization stage and two levels FDM was applied con
sidering the initial gas velocity, the axial distance between the atomizer
and the substrate, the superheating of the melt and the melt flow rate. The
validation of the optimized process parameters was done by processing the
Cu-Zn alloy, a high-density deposit, as high as 98.5% of the theoretical de
nsity with a very homogeneous microstructure being produced. (C) 2000 Elsev
