摘要： PROBLEM TO BE SOLVED: To solve such a problem accompanying a Cu-Al alloy sprayed sliding material whose sliding performance, mostly determined by (a) a wear resistance exerted by hard Si particles present in an Al-Si alloy phase and (b) a conformable surface formed on a Pb phase in a Cu-Pb alloy phase through abrasion by the opponent shaft, is deteriorated under certain sliding conditions such as in a compressor, owning to the defects of both alloys, i.e., an insufficient baking resistance of the Al-Si alloy phase and an insufficient wear resistance of the Cu-Pb alloy phase. SOLUTION: An aluminum phosphate compound coating film is formed on the surface of a Cu-Al sprayed layer. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To form a sliding layer having superior properties by scattering a uniform powder mixture of Al alloy powder and solid lubricant grains or further hard grains on the surface of a strip-like body made of Al alloy and then performing heating and compression under specific pressure and temp. conditions. CONSTITUTION:A uniform powder mixture 2 which has a composition consisting of, by volume, 1-30% of the grains of solid lubricant having stretchability, such as MoS2, graphite, and BN, and the grains of soft metal, such as Pb, In, Cd, and Sn, 0.5-10% of the grains of hard ceramics, such as the oxides, carbides, nitrides, and borides of metals, and the balance Al or Al alloy grains is laminated on a supporting plate 1, such as Al alloy strip-like body, steel plate, and copper alloy plate, and pressurized by a roll 3. The resulting preformed body 4 is heated up to about 600 deg.C in a heating furnace 5 to undergo the melting of the Al powder and then pressurized and solidified by means of a outlet roll 6 of the furnace 5, by which a composite Al plate 7 having a sliding layer where the solid lubricant powder and the hard powder are uniformly dispersed in the Al alloy is formed. This plate is joined to a steel strip 9, by which an Al type composite sliding material 14 excellent in lubricity can be produced.

摘要： PURPOSE:To improve the seizure resistance and diffusion prevention of an overlay by incorporating a specific ratio of C into the overlay at the time of depositing the overlay consisting of an Sn soft alloy, etc., via an intermediate layer on an alloy for the plain bearing. CONSTITUTION:The plain bearing is produced by plating the overlay consisting of the soft alloy essentially consisting of Sn or Pb or either thereof via a intermediator layer, such as Ni, on the alloy for the plain bearing deposited with a lining. C is previously incorporated at 0.02 to 0.5wt.% into the overlay at this time. The diffusion of the Sn of the overlay is effectively prevented in this way.

摘要： PURPOSE:To improve fittability and increase resistance against seizure and durability against fatigue by forming a coating layer consisting of solid lubricating agent in 90-55weight% and polyimide binder in 10-45weight% on the surface of aluminum-based bearing allay. CONSTITUTION:A coating layer 5 is provided on the outer surface of an adhesive layer 4 which is on a prefinished surface 3 of aluminum bearing alloy 2 overlaid on an SPCC (cold-rolled carbon-steel strip) backing metal 1. This coating layer 5 is composed of solid lubricating agent, such as MoS2, BN, WS2 and graphite, in 90-55 weight percent, and polyimide-type binder in 10-45 weight percent. This improves fittability, resistance against seizure, and durability against fatigue.

摘要： PURPOSE:To aim at enhancing the antiseizing ability, a wear resistance and a fatigue resistance with an additional process which is simple and cheap by forming an alumite layer on the outer surface of a lining material, by forming a close contact surface over the outer surface thereof so that the close contact layer follows up a roughened surface thereon, and by forming an overlay layer on the outer surface thereof. CONSTITUTION:A close contact layer 4 is formed by Ni-plating, Cu-plating or the like over the roughened outer surface of an alumite layer 2 which is formed over the outer surface of aluminum group alloy lining material 1, the close contact layer 4 being laid following up the roughened outer surface. The outer surface of an Pb group overlay layer 5 formed on the roughened surface of the close contact layer 4 is smoothened. Accordingly, it is possible to increase the adhesion force between the alumite layer 5 and the close contact layer 4 only with an additional process which is simple and cheap, thereby it is possible to enhance the antiseizing ability, the wear resistance and the fatigue resistance.

摘要： PURPOSE:To bring the capacity of a bearing material close to the level of Al or kelmt bimetal bearing alloy by dispersedly compounding specific inorganic fiber or whisker into a Pb-based alloy layer provided on the substrate of the bearing. CONSTITUTION:Fiber or whisker selected from Al2O3, Al2O3-SiO2, SiO2, SiC, BN, Si3N4, K2Ti6O13, etc., is dispersedly compounded into the Pb-based bearing alloy provided onto the substrate of the bearing material, by 5-50vol.%, for the total. Though the bearing material is slightly inferior to kelmet and Al bearing alloy in the aspect of fatigue resistance and load resistance, it is superior in the aspect of fitness, filling characteristics and seizure resistance.

摘要： PURPOSE:To obtain a good fatigue resistance under a high temp. by forming an Al layer, an Al-Sn group bearing alloy layer, and an overlay layer in order, and manufacturing an aluminum group slide bearing. CONSTITUTION:An Al layer 2, an Al-Sn group bearing alloy layer 3, and an overlay layer 4 are formed in order on the surface of a back metal 1, to manufacture a slide bearing. The Al layer 2 is made of pure Al, or a material in which a Cu and/or Mg of 2wt% or less is added to the pure Al, while the Al-Sn group bearing alloy layer 3 is made of a material in which an Sn of 3-20wt% and one or more kinds of Cr, Mn, Zr, V, Mo, Co, and Nb of 0.1-1wt% in total quantity are added to Al. And, the overlay layer 4 is made of a Pb group alloy. Thereby, an aluminum group slide bearing having excellent fatigue resistance even under a high temp. can be obtained.
