摘要： A ferrous alloy is formed with a Fe--Cr stainless steel having a Vickers hardness of 400 or more as a substrate and a Fe--Al diffusion layer having a thickness of 2 to 50 .mu.m. The diffusion layer contains at least 90 vol % of an intermetallic compound of Al and Fe relative to a total volume of the diffusion layer. The Al content included within a depth of at least 2 .mu.m of the diffusion layer is 35 to 65% by weight based upon total weight of a region of the diffusion layer ranging up to the thickness of at least 2 .mu.m. It is preferred to use as the substrate a precipitation-hardening stainless steel comprising 66 to 81.9 wt % of Fe, 15 to 20 wt % of Cr, 3 to 13 wt % of Ni, and one element selected from 3 to 6 wt % of Cu, 0.5 to 2 wt % of Al, and 0.01 to 0.2 wt % of a total of C and N, or a high carbon stainless steel comprising 73 to 89.9 wt % of Fe, 10 to 19 wt % of Cr, 0.1 to 1.2 wt % of C, and less than 3 wt % of Ni.

摘要： An inner cutter for a dry shaver has a plurality of blades 30 supported on a base 20 and is driven in hair-shearing engagement with an outer cutter 10 for cutting the hairs. The blades 30 are arranged in parallel with each other and are each provided on opposite sides at its top with cutting edges 32. The cutting edge 32 is defined between the top face of the blade and a rake fade 33 on the underside of the blade. The rake face 33 is inclined with respect to the top face at an angle of α (°), while the cutting edge is rounded at its tip to have a curvature radius R (μm) which satisfies a relation that R≧−0.067·α+4.7. With this result, the cutting resistance for cutting the hair can be lowered below a load necessary for bending the hair. Thus, the blade of the inner cutter can itself cut the hair without bending the hair, giving a flat cutting plane finish and enabling a close shave only with a fewer shaving strokes.

摘要： Fe-Cr-Ni-Al ferritic alloy capable of forming hot oxidation/corrosion resistive aluminum oxide scale in the surface thereof by exposure to oxidation environments at elevated temperatures. Due to the ferritic structure, the aluminum oxide scale is formed uniformly and densely to improve scale adherence, or prevent scale flaking. The mechanical properties of the ferritic alloy is considerably improved by incorporation of controlled amounts of Cr, Ni, and Al relative to each other, which are added to precipitate minute Ni-Al intermetallic compounds in the alloy matrix while retaining the ferritic structure. Such minute Ni-Al intermetallic compounds are thought to be responsible for improved mechanical properties, including high temperature strength, tensile strength, hardness and the like. Whereby, the alloy combine excellent hot oxidation/corrosion resistance and improved mechanical properties.

摘要： A ferritic alloy with a wear resistive oxide scale is obtained through the steps of pressing a ferritic alloy powder containing aluminum into a powder compact of a desired configuration, sintering the powder compact in a non-oxidizing atmosphere to provide a resulting sintered product, and heat-treating the sintered product in an oxidizing gas atmosphere in order to precipitate in the surface thereof alumina in the form of an alumina scale as the wear resistive oxide scale which is responsible for improved surface hardness or wear resistance. Due to the inherent porous nature of the sintered product, the oxidizing gas can readily penetrate deep into the surface of sintered product to facilitate the oxidization of the product surface into the alumina scale, in addition to that the oxidization depth can be controlled such as by the density of the product, which makes it possible to readily control the thickness of the alumina scale. The resulting alumina scale has an improved scale adherence due to the ferritic structure of the alloy.
