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

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