摘要： The present invention provides a process for producing a rare earth metal-based permanent magnet having, on its surface, a corrosion-resistant film containing inorganic fine particles having a specific average particle size and dispersed in a film phase formed from a silicon compound. In a heat treatment for forming a film by a hydrolyzing reaction and a thermally decomposing reaction of the silicon compound, followed by a polymerizing reaction, a stress is generated within the film by the shrinkage of the film. In the corrosion-resistant film formed by the producing process according to the present invention, however, such stress is dispersed by the presence of the inorganic fine particles and hence, the generation of physical defects such as cracks is inhibited. In addition, voids between the adjacent inorganic fine particles are filled with the film phase formed from the silicon compound and hence, the formed film is dense. Further, no alkali ions are contained in the film and hence, the film itself is excellent in corrosion resistance. Yet further, the film has an excellent close adhesion to the magnet achieved by an excellent reactivity with the surface of the magnet.

摘要： A surface treating process according to the present invention, a vapor deposited film is formed from an easily oxidizable vapor-depositing material on the surface of a work by evaporating the vapor-depositing material in a state in which the vapor deposition controlling gas has been supplied to at least zones near a melting/evaporating source and the work within a treating chamber. Thus, the vapor deposited film can be formed stably on the surface of a desired work without requirement of a long time for providing a high degree of vacuum and without use of a special apparatus. In addition, the use of the surface treating process ensures that a corrosion resistance can be provided to a rare earth metal-based permanent magnet extremely liable to be oxidized, without degradation of a high magnetic characteristic of the magnet. A surface treating apparatus according to the present invention includes a melting/evaporating source for melting and evaporating a wire-shaped vapor-depositing material containing a vapor deposition controlling gas, and a member for retaining a work on which the vapor-depositing material is deposited. The melting/evaporating source and the work retaining member are disposed in a treating chamber of the surface treating chamber. The apparatus further includes a vapor-depositing material supply means for supplying the wire-shaped vapor-depositing material containing the vapor deposition controlling gas to the melting-evaporating source.

摘要： An Fe—B—R based permanent magnet and metal pieces are placed into a treating vessel, where they are vibrated and/or agitated, whereby a metal film is formed on the surface of the magnet. A sol solution produced by the hydrolytic reaction and the polymerizing reaction of a metal compound which is a starting material for a metal oxide film is applied to the metal film and subjected to a heat treatment to form a metal oxide film. Therefore, it is possible to form, on the surface of the magnet, a corrosion-resistant film which can be produced easily and at a low cost without carrying-out of a plating treatment or a treatment using hexa-valent chromium and which has an excellent adhesion to the surface of the magnet and can exhibit a stable high magnetic characteristic which cannot be degraded even if the magnet is left to stand for a long period of time under high-temperature and high-humidity conditions of a temperature of 80° C. and a relative humidity of 90%. Thus, it is possible to provide an Fe—B—R based permanent magnet having an excellent corrosion resistance.

摘要： A rare earth metal-based permanent magnet has a film layer formed substantially of only a fine metal powder on a metal forming the surface of the magnet. The rare earth metal-based permanent magnet having the film layer on its surface is produced in the following manner: A rare earth metal-based permanent magnet and a fine metal powder forming material are placed into a treating vessel, where both of them are vibrated and/or agitated, whereby a film layer made of a fine metal powder produced from the fine metal powder producing material is formed on a metal forming the surface of the magnet. Thus, the formation of a corrosion-resistant film such as plated film can be achieved at a high thickness accuracy by forming an electrically conductive layer uniformly and firmly on the entire surface of the magnet without use of a third component such as a resin and a coupling agent.

摘要： With the deposited-film forming apparatus according to the first embodiment of the present invention, the distance between the tubular barrel and the evaporating section can be varied, unlike the prior art deposited-film forming apparatus and hence, the efficient formation of the deposited film on the surface of each of the work pieces accommodated in the tubular barrel and the inhibition of the softening of the formed film can be achieved simultaneously. Therefore, it is possible to inhibit the damaging of the deposited film formed on the surface of each of the work pieces and the production of projections on the deposited film, and to form a deposited film at a high quality in respect of a corrosion resistance and the like and at low cost. With the deposited-film forming apparatus according to the second embodiment of the present invention, the distance between the accommodating section defined in the tubular barrel and the evaporating section can be varied and hence, this deposited-film forming apparatus also exhibits an effect similar to that in the deposited-film forming apparatus according to the first embodiment of the present invention.
