ABSTRACT:
Improved core losses at high operating inductions are obtained in (110) [001] oriented silicon iron through the application of a new coating to the finish gauge material and thereafter heat treating to effect transformation of the underlying steel to the (110) [001] orientation, desulfurizing the underlying steel as well as decarburizing the same. The coating, as fused, is characterized by excellent adherence and a high interlaminar resistance value.
