摘要： PURPOSE:To improve the corrosion-resisting property of a magnet by a method wherein a corrosion protective covering of nA2O.mSiO2 (A indicates one or two or more kinds selected from the group consisting of Li, Na and K, and m/n indicates the range of 2.0-4.0) is provided on the surface of a rare-earth metal-iron permanent magnet. CONSTITUTION:After the alloy of the composition of Nd0.15Fe0.75B0.10 has been fused in an Ar atmosphere, it is coarse-pulverized and then pulverized until an average grain diameter of 3mum or thereabout is obtained. Then, this fine powder is molded by applying the pressure of 1.5t/cm in the magnetic field of 10kOe. The obtained molded body is put in the Ar atmosphere again, it is sintered, and after it has been cooled down to room temperature, a heat treatment is performed at 600 deg.C for abut 1hr. Subsequently, the coating material, consisting of Li2O, Na2O, K2O, SiO2, zinc dust, water, A2O/SiO2 in the specific molar ratio, is painted with a brush on the surface of the permanent magnet obtained as above and it is dried up. through these procedures, oxidization can be prevented even when the material such as rare-earth-iron or rare-earth- iron-cobalt, which is susceptible to oxidization, is used.
