A sliding element, such as a bearing, and a method of manufacturing the sliding element, is provided. The sliding element is formed of an aluminum alloy material which includes zinc in an amount of 5 wt. % to 83 wt. %. The sliding element may also include silicon and/or magnesium. The sliding element is typically formed by casting, heat treating at a temperature of 400° C. to 577° C., and cooling at a rate of less than 50° C. per hour to a temperature ranging from 400° C. to 200° C. The aluminum alloy material is then heat treated at a temperature of 100° to 275° C. for at least 5 hours to form a soft phase consisting essentially of the zinc. The second heat treatment, or possibly both heat treatments, may not be required when the aluminum alloy material includes the magnesium.

Bearing formed of an aluminum alloy material and method of manufacturing

A bearing including a backing formed of a steel material, a lining formed of aluminum or an aluminum alloy, and a diffusion barrier layer disposed between the backing and the lining is provided. The diffusion barrier layer is formed of nickel or a nickel alloy and has a thickness ranging from 1 micron to 100 microns. The bearing is typically formed by cladding the lining or plating the steel backing with the diffusion barrier layer, bonding the lining and the backing with the diffusion barrier layer between, heating to a temperature of at least 400&#xb0; C., and forming the bearing into a shape after or before the heating step.

Bearing and method of manufacturing permitting high temperature heat treatment

A sliding bearing includes a bearing surface which comprises a material in which an alloy material based on CuSnX (0.01&#x3c;X&#x3c;9), CuNi2Si, or CuFe2P is used. A method for producing such a sliding bearing and a use for CuNi2Si, CuFe2P, and CuSnX in a sliding bearing is also provided.

Method for producing a sliding bearing comprising a CuNi2Si, CuFe2P or CuSnX compound

The invention relates to a copper alloy such as, for example, CuNi6Sn5Fe2P0.15, which has hard particles such as, for example, Fe3P or Fe2P and optionally solid lubricants such as, for example, hexagonal boron nitrides or graphite. The invention further relates to the use of said copper alloy for a bearing and to a bearing having said copper alloy. The invention further relates to a method for producing a bearing having a copper alloy, wherein a metal powder is produced, for example, by means of melt atomization, hard particles and optional solid lubricants are optionally added to said powder, and the powder is sintered onto a substrate. Finally, the invention relates to an alternative method for producing a bearing, wherein the copper alloy is applied to a substrate by means of casting or plating or wherein the bearing is made completely of the copper alloy.

Copper alloy, use of a copper alloy, bearing having a copper alloy, and method for producing a bearing composed of a copper alloy

A method of forming an engineered material, for example a material for use in a bearing, is provided. The method includes forming a template polymer microlattice by disposing a perforated mask over a reservoir of ultra-violet (UV) curable resin in liquid form, conveying beams of light through the perforated mask and into the reservoir along paths, and transforming the liquid UV curable resin along the paths into a plurality of interconnected solid polymer fibers. The method further includes applying a metal material to the template polymer microlattice to form a microlattice of the metal material, and removing the template polymer microlattice from the metal microlattice. The method next includes disposing a low friction material in interstices of the metal microlattice, and sintering the low friction material disposed in the interstices of the metal microlattice.

Method of forming a high strength low friction engineered material for bearings and other applications

A continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.

Bi-material strip and a method of bonding strips of different materials together

A bearing having improved wear resistance has a bearing material of a copper-tin-bismuth alloy which may also include phosphorus which has excellent strength, due to the solid solution of copper, tin and phosphorus (when used), attached to a steel backing shell. The material also has good lubricity as a result of the presence of the bismuth which also promotes tin mobilization and formation of a layer of tin on the bearing surface upon use of the bearing. The addition of small amounts of relatively small hard particles in the copper-tin-matrix, particularly FeP, MoSior a mixture thereof, provides a suitable hard surface artifact to improve the wear resistance of the bearing material. The bearing includes a sintered powder compact bearing material of a copper-tin-bismuth alloy powder and a metal compound powder which is bonded to a steel backing shell, wherein the metal compound powder has an average particle size of less than 10 &#x3bc;m.

Wear resistant lead free alloy bushing and method of making

A high strength, low friction engineered material includes a low friction material filling interstices of a metal microlattice. The metal typically comprises 5 volume % to 25 volume % and the interstices typically comprise 75 volume % to 95 volume %, based on the total volume of the metal microlattice and the interstices. The low friction material preferably fills 100 volume % of the interstices. The metal microlattice can be formed of a single layer, or multiple layers, for example layers of nickel, copper, and tin. The low friction material is typically a polymer, such as polytetrafluoroethylene (PTFE), polyamide (PAI), polyetheretherketone (PEEK), polyethylene (PE), or polyoxymethylene (POM). The low friction material can also include additive particles to modify the material properties. The engineered material can be used in various automotive applications, for example as a bearing, or non-automotive applications.

High strength low friction engineered material for bearings and other applications

The invention relates to a lead-free sliding bearing material having a Cu-based or CuSn-based sintered matrix and a solid lubricant. The solid lubricant contains hexagonal boron nitride in a fine-grained distribution with a mean particle size of 10 &#x3bc;m or less, wherein agglomerates of the particles of hexagonal boron nitride are not greater than 200 &#x3bc;m. The invention also relates to a sintering powder for producing the sliding bearing material, a sliding bearing composite material having a steel protective layer and a bearing layer composed of such a sintered-on sliding bearing material. The invention also relates to a sliding element composed of a sliding bearing composite material of the type mentioned above.
