Optimization of the method of oxide coating of metallic iron powder particles

This article considers the issue of wide implementation in various branches national economy caused intensive growth electric machines production. Due to high specific consumption magnetic materials production machines, a very promising direction is development waste-free technology manufacture cores and by methods powder metallurgy. The use metallurgy allows reducing losses electrical steel eliminating many labor-intensive operations, using for production, it possible obtain sufficiently efficiency values and reduce hysteresis losses.
