Abstract
The pole faces of magnetic core members are improved by subjecting the pole faces of laminated members formed of an alloy comprising 0.5-7% Si, 0.1-2% Al, and the balance iron and unavoidable impurities to a nitriding process. The members may be coated on all except the pole faces with a thin layer of tin dust lacquer and heated at 980 DEG F. in an atmosphere of ammonia for 10 hours and then at 1067 DEG F. for a further 5 hours, being finally cooled to 300 DEG F. in the same atmosphere. The tin dust lacquer is removed and the members may be assembled to form a magnetic contact device.
