Abstract
The electromagnetic induced segregation (EIS) technology allows an effective segregation of silicon crystals at the surface of cylinder bores. The Si-content of the used hypereutectic alloy could be reduced without changing properties of the surface. The numerical model allows the calculation of electrical data of the inductor system to dimension the transformers for current, power and voltage. The power induced into the melt is also calculated to be taken into account during simulation of the solidification. An essential parameter of the inductor system is the frequency of the current. In the field of induction heating, induction melting, induction hardening and crystal growing, the frequencies from several hundreds of Hz up to a few MHz are used. With suitable casting parameters it is possible to produce cylinder surfaces by electromagnetic induced segregation that is on a par with common cylinder surfaces.
