摘要： The present invention addresses the problem of providing a method for producing an RFeB system magnet with high coercivity by preventing a coating material from peeling off the surface of a base material during a grain boundary diffusion treatment. Provided is a method for producing an R L 2 Fe 14 B system magnet which is a sintered magnet or a hot-deformed magnet containing, as the main rare-earth element, a light rare-earth element R L which is at least one of the two elements ofNd and Pr, the method including the steps of: applying, to a surface of a base material M of the R L 2 Fe 14 B system magnet, a coating material 10 prepared by mixing a silicone grease 11 and an R H -containing powder 14 containing a heavy rare-earth element R H composed of at least one element selected from the group of Dy, Tb and Ho; and heating the base material M together with the coating material. The silicone having a siloxane bond prevents the coating material 10 from peeling off the surface of the base material M during the heating process. The improved adhesion of the coating material 10 to the base material M facilitates transfer of R H into the grain boundaries of the base material M, whereby the coercivity is increased.

摘要： An Au plated film 12 is formed on the surface of a plate-formed metal base 13 composed of a metal less noble than Au, and the product is cut along a planned cutting line 18 reflecting a contour of a desired component, to thereby form a separator 10. Thus-formed separator 10 has the Au plated film 12 formed on the main surface 10a thereof, and has a cutting plane 16 formed as an end face 16 stretched up to the main surface 10a. The metal base 13 exposes in a part of the cutting plane 16, in a width of the exposed region of 1 mm or less. This is successful in providing a metal component for fuel cell which is satisfactory in the corrosion resistance and allows easy fabrication at low costs, a method of manufacturing the same, and also in providing a fuel cell having thus-fabricated metal component for fuel cell.

摘要： Disclosed is a corrosion resistant conductive part, which is made by forming a thin plated gold layer of thickness 100nm or less on a stainless steel sheet, and for which high corrosion resistance is guaranteed even with a very thin gold layer. The part is characterized in that the maximum value "v" of atomic concentration of gold given by Auger analysis is at least 98% of the total atomic concentrations of all the elements, which is deemed to be 100%, in the thin gold layer ranging from the surface to the interface of the gold layer and the metal substrate, at which the descending curve of gold crosses the ascending curve of the most predominant component of the substrate metal.

摘要： The present invention addresses the problem of providing a grain boundary diffusion treatment jig that does not easily become fused with a base material S an R L 2 Fe 14 B system magnet having a surface coated with an adhesion material P containing an element R H (which is at least one element selected from the group of Dy, Tb and Ho) when subjected to a heating process for grain boundary diffusion treatment. The grain boundary diffusion treatment jig 10 includes a plate-shaped base 11 having a surface with a number of projections 12 arranged so that the tips 121 of the projections 12 lie in one plane, and the surfaces of the tips 121 are made of a ceramic material. Since the contact area between the adhesion material applied to the surface of the base material and the grain boundary diffusion treatment jig is reduced by the use of the projections 12 for supporting the base material S, and since a ceramic material that does not easily react with the adhesion material P is used, the fusion of the base material S and the grain boundary diffusion treatment jig 10 is less likely to occur in the aforementioned heating process.
