摘要： A preparation method for a W—Cu composite plate with a Cu phase in finger-shaped gradient distribution is provided. The method includes adding WOX powder obtained with ammonium metatungstate as a raw material into W powder through a combustion synthesis method, adding a binder and a pore-forming agent to prepare a slurry, then performing tape casting, soaking in water and sintering to obtain a W framework with pores in finger-shaped distribution, and then infiltrating Cu to obtain a target product. The Cu phase in the W—Cu composite material prepared by the present method is distributed in a finger-shaped gradient manner from an infiltration surface to the interior of a specimen, the Cu phase and the W phase are mutually pinned, and the W—Cu interface has good bonding strength. The present method has the characteristics of adjustable material component performance, simple process, low cost, suitability for large-scale production and the like.

摘要： By melting a shaping material in which a metal powder and a binder are mixed and by carrying out injection molding (primary shaping) in an injection mold, an injection molded body, or an intermediate shaped body are produced. The injection molded body or the intermediate shaped body is placed by a transfer mold and is subjected to a gravity shaping (secondary shaping) with a transformation. A sintered body is manufactured by carrying out debindering and sintering to the injection molded body.

摘要： A rotary compressor has a combined vane-roller structure that may ensure improved productivity and reliability through control of mechanical properties. The rotary compressor includes a coupling groove which is disposed at one side of an outer circumferential surface of the roller, which has a circular arc shape from an outer diameter of the roller towards an inner diameter of the roller, and which is configured to couple a vane and the roller, and includes a ferrosoferric oxide (Fe3O4) film on a surface of the coupling groove. A manufacturing method of the rotary compressor is also described.

摘要： Provided is a valve seat insert for an internal combustion engine, which has both an excellent heat dissipation property and excellent wear resistance. The valve seat insert for an internal combustion engine is used while being press-fitted into an aluminum alloy cylinder head, is made of an iron-based sintered alloy, is formed by integrating two layers of a functional member side layer and a supporting member side layer, and has a plating film on at least an outer peripheral side. The plating film is preferably a copper plating film. The plating film is a plating film having a thickness of 1 to 100 μm and a hardness of 50 to 300 HV, and the hardness of the plating film is adjusted so as to satisfy a range of 1.05 to 4.5 times hardness of the cylinder head in Vickers hardness HV. Pores contained in the valve seat insert are preferably sealed with a curable resin before plating treatment. Consequently, a valve seat insert for an internal combustion engine which does not go through complicated processes, is not accompanied by a significant decrease in wear resistance compared with the prior art, and has an excellent heat dissipation property is provided. If a roughened surface region is further formed at at least one portion on the outer peripheral surface of the valve seat insert in addition to the plating film, a falling out resistance property is improved. The same effect can be obtained even if the valve seat insert is a single layer of only the functional member side layer.

摘要： In one example in accordance with the present disclosure, a system is described. The system includes a fracture channel controller to determine fracture channels for a three-dimensional (3D) printed object. Portions of the 3D printed object along fracture channels are to be solidified to a lesser degree as compared to non-channel portions of the 3D printed object. The system also includes an additive manufacturing controller to control an additive manufacturing device. The additive manufacturing controller controls the additive manufacturing device to 1) solidify portions of a layer of powdered build material to form a slice of the 3D printed object and 2) selectively solidify fracture channels in the slice, wherein the fracture channels are solidified to a lesser degree as compared to non-channel portions.
