摘要:
A method of improving the surface insulation resistance of electrical steels having an insulative coating thereon by subjecting the electrical steels to electrochemical treatment as part of the routing thereof, to remove small metallic nodules, particles and the like extending through or protruding above the insulative coating. Following the electrochemical treatment, the electrical steels are rinsed and dried.
