PURPOSE:To obtain the titled fine powder with high moldability by carrying out melting and spraying with a plasma gun and a spray nozzle in place of water atomizing or gas atomizing when metallic powder is manufactured by powdering molten metal. CONSTITUTION:An alloy consisting of 17-45wt% Cr, 5-30wt% Co and the balance Fe is melted by heating to a very high temp. in vacuum with a plasma gun, and the molten alloy is sprayed from a nozzle. Hardly oxidized fine Fe-Cr- Co magnet alloy powder can be obtd. by this method, and finally an Fe-Cr-Co magnet with superior magnetic characteristics can be manufactured. |
