METHOD FOR TREATING ARTICLES MADE FROM MAGNETICALLY SOFT ALLOYS

A method according to the present invention is intended for treating articles for magnetically soft alloys employed in radio-electronic, relay and switching apparatus, in optical-and-mechanical and automation systems. The method consists in saturating the surface of the articles with chromium inside a powder chromizing mixture at a temperature in excess of 800.degree.C, the articles being heated at a rate not higher than that of recrystallization of a metal of the articles and the rate of diffusion processes of saturating the articles. The articles are cooled at a rate close to that of phase transformations and formation of a magnetic structure in the metal of the articles, for example, at the rate of 20-200 degree/hour below the Curie point. To enhance the magnetic properties and the stability thereof, as well as wearability and the resistance of the items to corrosion, chromizing of the article surfaces is conducted in an inert gas atmosphere.
