Abstract
The paper
presents the relative magnetic permeabi lity and the calculation model of por ous metal foams First, the porosity of
porous foam metal is tested and obtained by the fusible paraffin; the magnetic permeability of three kinds of porous metal
foam, that is, Fe, Cu, with the same structure param eters and different relative permeability are tested by vibrating sample
magnetometer (VSM). Based on the equivalent reluctivity, the initial relative permeability of the electrodeposited metals is
simulated and the calculated results are close to the testing results. The results show that the calculation model can be used
to describe the relative permeability of electrodeposited metals, at the same time, according to the calculation, the relative
permeability of porous metal foam s will increase with the in creased relative permeability of electrodeposited metals, and
decrease with the increased porosity, which provide the theorical and experimental proof for the research on magnetic
characteristics of porous metal foams..
