摘要： A compressor component incorporated into a compressor having a compressor body (200) and a compressor pulley mechanism (400) transmitting a driving force to the compressor body (200) has an austenite grain with a grain size number falling within a range exceeding 10, a fracture stress value of at least 2650 MPa, or a hydrogen content of at most 0.5 ppm. This provides a compressor component and a compressor bearing with a long fatigue life, a high anti-crack strength, and a reduced secular dimensional variation.

摘要： In a piston-cylinder assembly of an internal combustion engine, especially a two-stroke engine, at least the piston-sliding surface of the cylinder is made of an aluminium alloy. Moreover, the basic material of the piston (1) is an alluminium alloy and at least 80 % of its sliding surface is given a sliding coating (3, 4). The sliding coating (3, 4) on the piston (1) is usually metallic and galvanically applied. The aim is to provide an economically producible piston coating with properties at least as good as those of the former galvanically applied coatings. To this end the cylinder sliding surface has a roughness Ra of less than 1 mu m, while the piston sliding surface consist of resin-bound graphite. The piston rings (6) are made of cast iron or steel and have a convex sliding surface.

摘要： The invention relates to a guide arrangement, especially for a piston-cylinder arrangement, comprising a cylinder (3) in which a bearing section of a piston (2) can be displaced axially along its inner bore (5) configured as a piston bearing surface (6) and a piston (2) to which a connecting rod can be coupled by means of a pin. At least two cylindrical and peripheral bearing sections (9a, 10a) radially delimiting the piston (2) and serving as support on the bearing surface (6) of the cylinder (3) are releasably arranged on said piston (2) by means of two parts (7, 8) of the piston (2), at least one of which penetrates a central opening of the bearing sections (9a, 10a). The forces and torques are evenly distributed on the at least two bearing sections in the axial extension of the piston (2) in such a way that the bearing sections are arranged outside the axle of the pin and at least one section (9a) of the at least two bearing sections (9a, 10a) is completely arranged on one side of the axle of the pin (20) and at least the other section (10a) of the at least two bearing sections (9a, 10a) is completely arranged on the other side of the axle of the pin (20). In addition, the bearing sections (9a, 10a) are fixed at a fixed reciprocal axial distance (11) in relation to each other. Force is transmitted from the pin to the bearing sections (9a, 10a) exclusively through the central parts (7, 8) of the piston (2). A favorable tribologic pairing is achieved in that one of the materials of the pairing bearing section (9a, 10a) guide surface (6) is chosen from the group comprising polycrystalline diamond, amorphous hydrocarbon, tetragonally coordinated hydrocarbon and metal-containing hydrocarbon and in that the other material of the pairing is selected from the group comprising mesophase graphite and ultrafine grain graphite.

摘要： A three-dimensional piston molding is fabricated from a mixture of chopped, carbon tow filaments of variable length, which are prepregged with carbonaceous organic resins and/or pitches and molded by conventional molding processes into near net shape, to form a carbon-fiber reinforced organic-matrix composite part. Continuous reinforcement in the form of carbon-carbon composite tapes or pieces of fabric can be also laid in the mold before or during the charging of the mold with the chopped-fiber mixture, to enhance the strength in the crown (21) and wrist-pin areas (23). The modled chopped-fiber reinforced organic-matrix composite parts are then pyrolyzed in an inert atmosphere, to convert the organic matrix materials to carbon. These pyrolyzed parts are then densified by reimpregnation with resins or pitches, which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes. Once the desired density has been achieved, the piston molds are machined to final piston dimensions, and piston ring grooves are added. To prevent oxidation and/or to seal the piston surface or near surface, the chopped-fiber piston (20) is coated with ceramic and/or metallic sealants; and/or coated with a catalyst.

摘要： An improved structure for carbon-carbon composite piston architectures is disclosed. Initially, the carbon fabric or tape layers are prepregged with carbonaceous organic resins and/or pitches and these plies (21) laid up or molded about a mandrel, to form a carbon-fiber reinforced organic-matrix composite billets (20) shaped like a 'U' channel having legs (26, 27), a 'T'-bar, or a combination of the two. The molded carbon-fiber reinforced organic-matrix composite part is then pyrolized in an inert atmosphere, to convert the organic matrix materials to carbon. At this point, cylindrical piston blanks (22) are cored from the 'U'-channel, 'T'-bar, or combination part. These blanks are then densified by reimpregnation with resins or pitches which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes. Once the desired density has been achieved, the piston billets are machined to final piston dimensions; coated with oxidation sealants; and/or coated with a catalyst.

摘要： An economical resistant bearing surface reinforcement is to be provided for a reciprocating piston of an internal combustion engine, especially one using an aluminium alloy as the basic material, especially one such designed for an engine with cylinder running surface of alluminium alloy. To this end, the prior art galvanically applied steel, nickel or chromium coatings are to be replaced by a synthetic-resin-bonded graphite coating with incorporated metal particles. The metal particles may be nickel, steel, bronze, chromium, silver or alloys thereof. The running layer may also be a thin, adhesively secured metal foil. As a further alternative, the bearing layer may also be formed by metal plates secured to the piston body mechanically or by casting.
