  Optimization of power loss in soft magnetic components basis on the choice of
the best technological parameters values. Therefore, the power losses have been
measured in Somaloy 500 samples for a wide range of frequency and magnetic
induction. These samples have been prepared under a wide range of the hardening
temperatures and pressures. The power loss characteristics have been derived by
assuming that investigated samples obeyed the scaling law. Agreement obtained
between experimental data and the scaling theory has confirmed this assumption.
Moreover, the experimental data of the given sample have been collapsed to a
single curve which represented measurements for all values of frequency an
magnetic induction pick. Therefore, the scaling transforms the losses
characteristics from the two dimensional surfaces to the one dimensional
curves. The samples were produced according two methods: for different
pressures with constant temperature and at different temperatures with constant
pressure. In both cases the power losses decrease with increasing pressure and
with increasing temperature. These trends in decreasing losses stopped for
certain critical values of pressure and temperature, respectively. Above these
values the power losses increase suddenly. Therefore, the mentioned above the
critical pressure and the critical temperature are sought after solutions for
optimal values. In order to reduce the parameters values set the limit curve in
the pressure-temperature plane has been derive. This curve constitutes a
separation curve between the parameters values corresponding to high and low
losses.
