    Abstract: An Fe-B-R permanent magnet has an excellent adhesion to an Fe-B-R permanent magnet, stable high magnet characteristics, improved abrasive and corrosion resistances, and an excellent electrical insulation. Especially, the initial magnetic characteristics hardly deteriorate even if it is left for a long time in an environment of a temperature of 80 DEG C and a relative humidity of 90 %. To produce such an Fe-B-R magnet, the surface of a magnet blank is cleaned by ion sputtering, an Al or Ti film is formed on the cleaned magnetic blank by vapor phase film-forming, such as ion plating, an aluminum oxide film is formed on the Al or Ti film by vapor phase film-forming, such as ion plating, while introducing O2 simple substance gas or an O2-containing gas. Thus, the adhesion of the deposited film is significantly improved by the aluminum oxide film, and an excellent corrosion resistance is achieved, thereby providing an Fe-B-R permanent magnet having stable magnet characteristics thanks to the corrosion and abrasive resistances and electrical insulation of the deposited corrosion-resisting metal film.

    Abstract: The invention concerns materials for permanent magnets, in particular, materials based on ternary compounds such as neodymium-iron-boron, containing one stable ternary compound such type as Fe-B-R (where R - one or some rare earth metals including yttrium) with a tetragonal structure and nonmagnetic compounds. This invention can be used for manufacturing of permanent magnets for electrical engineering, electronics, instrument-making and so on. The technical result of the present invention consists in increasing in reproducibility of magnetic properties and manufacturability of obtaining a material for permanent magnets based on the Fe-B-R ternary compound. The result is achieved by means of using the amorphous oxidic derivatives of rare earth metals as nonmagnetic compounds in the material for permanent magnets based on the Fe-B-R ternary compound containing at least one stable ternary compound of the Fe-B-R type and nonmagnetic compounds in the following component amount, weight %: at least one stable Fe-B-R type ternary compound base, amorphous oxidic derivatives of rare earth metals 2.8-3.8. In this case an amount of rare earth metals in the stable Fe-B-R type ternary compound exceeds an amount of rare earth metals in the amorphous oxidic derivatives of rare earth metals by a factor of 40-90 and the interface between the amorphous oxidic derivatives of rare earth metals (phase I) and the stable Fe-B-R type compound (phase II) is 6000-12000 cm /cm . The material based on the Fe-B-R ternary compound with addition of dysprosium and cobalt, containing amorphous compounds of the oxidic derivatives of rare earth metals, aluminium and scandium, was used for manufacturing of permanent magnets having the following magnetic properties: Br = 12.5-14 kG, Hcb = 10.5-11.5 kOe, (BH)max = 35-46 MGOe. The proposed material for permanent magnets is characterized by the high reproducibility of magnetic properties (output of sound goods 60-90 %) and by the high manufacturability (technological fitness of the powder blend 48-96 hours).
