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 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

In a process for producing a lead-free sliding bearing material, a material which is based on copper and contains iron and phosphorous is atomized to form a powder.

Process for producing a lead-free sliding bearing material

CuFe2P is used in a plain bearing or as a plain bearing material. A plain bearing composite material which comprises a supporting layer is provided with a bearing metal layer based on CuFe2P.

Plain bearing material

In a method for producing a plain bearing, an aluminum-iron-silicon alloy is rolled onto a steel backing, wherein the ratio of iron to silicon is between 2:1 and 4:1. A plain bearing has a sliding surface of such an aluminum-iron-silicon alloy.

Method for producing a lead-free, plated aluminium plain bearing

In a method for producing a lead-free sliding bearing, a copper-based material comprising a total of 0.1% to 3% of the elements aluminum, magnesium, silicon, titanium, zircon, and chromium is sintered. Additionally, up to 15% tin can be included in order to ensure optimal properties for use in the internal combustion engine.

Method for producing a lead-free sliding bearing

The invention relates to a slide bearing composite material having at least one carrier layer and a sintered bearing metal layer. The sintered bearing metal layer is designed in at least one layer region as a gradient layer.

Slide bearing composite material

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.
