摘要： PROBLEM TO BE SOLVED: To produce a sintered friction member by means of a single sintering stage while saving labor and time and also to improve the joining strength between a ferrous base material and a coppery friction material by enabling the simultaneous sintering of a ferrous powder and a coppery alloy powder. SOLUTION: This sintered friction member consists of a ferrous base material 1 and a friction material 2 composed of a Cu-Ni alloy formed integrally with the base material 1 and is obtained by subjecting a ferrous powder and a Cu-Ni alloy powder to simultaneous compacting and simultaneous sintering. This Cu-Ni alloy contains Ni by 10 to 70 wt.%. Because the Cu-Ni alloy, containing Ni by the prescribed amount or more, is adopted as a friction material, the coppery friction material and the ferrous base material can be subjected to simultaneous compacting and simultaneous sintering and formed into the sintered friction member. Further, in the joining surface between the ferrous base material and the coppery friction material, the ferrous powder and the Cu-Ni alloy powder are tangled together sufficiently, and as a result, the joining strength between the ferrous base material and the coppery friction material can be satisfactorily improved.

摘要： PROBLEM TO BE SOLVED: To produce a friction material for synchronizer ring, having a prescribed porosity and excellent in wear resistance, etc., by mixing a powder mixture of Cu and Zn, a specific ferrous alloy powder, a graphite powder, and a specific alloy or metal powder with a Cu-Zn alloy powder, compacting the resultant powder mixture, and then sintering the resultant green compact. SOLUTION: A powder mixture is prepared by mixing 3-25%, by weight, of a powder mixture of at least one kind among the powders of Fe-Ti, (nitrided Fe)-Ti, ZrO2 , stabilized zirconia, etc., and graphite powder and further 2-15% of a powder of a Cu alloy, such as Cu-P, Cu-Sn, and Cu-Zn alloys, having a solidus line lower than the sintering temp. for its sintered compact or a metal, such as Sn, having a melting point lower than the sintering temp. with 60-95% of at least either of a Cu-(20 to 40%)Zn alloy powder and a powder mixture of Cu and Zn, consisting of 60-80% Cu powder and 20-40% Zn powder. This powder mixture is compacted, and the resultant green compact is pressed on the sliding part of the main body of a synchronizer ring, which is then sintered. By this method, the friction material for synchronizer ring, excellent in wear resistance, seizure resistance, etc., can be produced.

摘要： PURPOSE:To make possible manufacture of a smaller, lighter and more inexpensive composite flywheel by a method wherein metallic powder and thermoplastic resin are mixed, fused, pressed, kneaded and this fused and kneaded material is injected into a mold. CONSTITUTION:To take an example, metallic powder of 70-95wt% of metallic powder and thermoplastic resin of 5-30wt% are mixed uniformly and is heated, fused, pressed, kneaded and molded into pellets. The pellets are heated in an injection molding machine and injected into a mold to obtain a desired flywheel. Polyolefin resin, vinyl chloride resin, polycarbonic resin, etc., various copolymers and modifiers of these resins are designated as representative thermoplastic resins and from the point of viscosity, etc., nylon is most desirable among them. Powder of Fe, Zn, Sn, Pb, Cu and those alloys are used as metallic powder and Fe powder is most desirable from the point of cost.
