A sliding member includes: a lining layer formed from an alloy having a predetermined shape; and an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of a resin, the overlay layer sliding with a shaft, the overlay layer including a raised portion a height of which in a predetermined area including each of an edge in an axial direction of the shaft is greater than a height of another area of the overlay layer.

Sliding member

Bearinghas lining layerthat is formed of an alloy having a predetermined shape and that has chamfered portion, and overlay layerthat is formed of a resin on an inner circumferential surface of lining layer, the inner circumferential surface sliding relative to a mating shaft, and that covers at least a portion of chamfered portion

In a method, in which a plain bearing alloy layer is bonded to a surface of a backing steel sheet, and, a Bi-based overlay layer is then deposited on the plain bearing alloy layer by electroplating, replacement of Bi with the backing steel sheet and deposition of Bi on the backing steel sheet are prevented. Prior to the step of electroplating of the Bi-based overlay layer, the following metals and the like are formed on at least the back surface of the backing steel sheet. An electrochemically more noble metal than Bi, an electrochemically more base metal than Bi and capable of forming a passivation state, or resin.

Method for producing sliding member, sliding member, and substrate material of sliding member

Seizure resistance and wear resistance of Cu&#x2014;Bi&#x2014;In copper-alloy sliding material are enhanced by forming a soft phase of as pure as possible Bi. Mixed powder of Cu&#x2014;In cuprous alloy powder and Cu&#x2014;Bi containing Cu-based alloy powder is used. A sintering condition is set such that Bi moves outside particles of said Cu&#x2014;Bi containing Cu-based powder and forms a Bi grain-boundary phase free of In, and In diffuses from said Cu&#x2014;In containing Cu-based powder to said Cu&#x2014;Bi containing Cu-based powder.

Process for production of sintered copper alloy sliding material and sintered copper alloy sliding material

An object of the present invention is to provide a sliding member suitable to a soft mating member low in hardness. The present invention relates to a sliding member for sliding with a mating member having a ferrite phase at least on a surface thereof, the sliding member including a coating layer containing a binder resin, molybdenum disulfide, and hard substance particles.

Sliding member and sliding material composition

With regard to an Al&#x2014;Cr&#x2014;Zr based alloy having annealing temper, a high temperature strength at 180 to 200 degrees C. is ensured. An aluminum alloy for a plain bearing having improved fatigue resistance is to be provided. An aluminum alloy for a plain bearing solving the problems has a composition of 3 to 7 mass % Mg, 0.1 to 0.3 mass % Cr, and 0.1 to 0.3 mass % Zr, with the balance being Al and inevitable impurities. A principal structure of the aluminum alloy consist of an Al matrix containing solute Mg, minute particles of Cr, and Zr.

Aluminum alloy for plain bearing, plain bearing and production method for the bearing

An object of the present invention is to provide a sliding member capable of rapidly wrapping a mating member, and reducing the surface roughness of the mating member after wrapping. The present invention relates to a sliding member for sliding with a mating member subjected to hardening treatment, the sliding member including a coating layer containing a binder resin, molybdenum disulfide, and hard substance particles in massive form.

A sliding bearingis composed of a pair of halved bearingsand is provided with crush reliefsE,E in positions adjoining abutment surfacesB,B of these halved bearings. Chamfered portionsD,D are formed in inward edge portions of the above-described abutment surfacesB,B, and a dust pocketis formed on the middle side of the chamfered portionsD,D. The relative angle &#x3b1; formed by the above-described crush reliefsE,E with sliding surfacesin positions adjoining the crush reliefsE,E is set at 0.69&#xb0; or more.

Sliding bearing

The copper alloy (lining) prevails in an overwhelmingly large amount in a plain-bearing layer structure. Cu of the plain bearing copper-alloy diffuses into the Sn-based overlay diffuses into the Sn-based overlay and detrimentally impairs the performance of the overlay. The present invention takes a measure against this problem. An Sn-based overlay having a thickness of 3 to 19 &#x3bc;m is deposited by electro-plating without an intermediate layer for diffusion prevention on a plain-bearing layer, which contains Sn and Ni in a total amount of more than 4 mass % to 20 mass % (the minimum amount of Sn is 4 mass %) and has a hardness of Hv 150 or less.

Plain bearing

A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.

Slide bearing

A sliding bearing for an internal combustion engine including a copper-based bearing alloy including silver and tin upon which an overlay is applied. The overlay comprises resin and MoS , and the adherence of the overlay to the alloy is enhanced by a roughened alloy surface formed of grooves extending in the sliding direction.

Sliding bearing for internal combustion engine

An aluminum alloy which is able to use not only expensive TiC particles, but also inexpensive dispersed reinforcing particles and which is further raised in high temperature strength without requiring an increase in dispersed reinforcing particles, comprised of Sn: 2 to 20 wt %, Cu: 0.1 to 3 wt %, Ca: 0.02 to 1.5 wt %, at least one element selected from the group comprised of Mg, Cr, Zr, Mn, V, Ni, and Fe: not more than 2 wt % in total, at least one type of reinforcing particle selected from the group comprised of TiC particles, ZrC particles, and Al O particles: 0.1 to 5 vol % in total, and the balance of Al and unavoidable impurities; a slide bearing comprised of that aluminum alloy; and a slide bearing comprised of a bearing body made of that aluminum alloy provided on its surface with a resin coating layer comprised of a heat-curing resin and a solid lubricant.

Aluminum alloy and slide bearing

In order to improve the wear resistance of the swash plate of a swash-plate type compressor, on which plate copper alloy is flame-sprayed, a composite material, which consists of copper or first copper alloy (for example Cu&mdash;Pb alloy) including at least unmelted phase and aluminum or first aluminum alloy (for example Al&mdash;Si alloy) including at least melted phase, is flame sprayed on the sliding surface with a shoe.
