Publication number: 20080166578Abstract: 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 Fe3P, MoSi2 or 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 ?m.Type: ApplicationFiled: July 31, 2007Publication date: July 10, 2008Applicant: FEDERAL-MOGUL WORLD WIDE, INC.Inventors: David M.

Patent number: 6444086Abstract: Existing devices for vacuum coating substrates having different shapes, either in continuous or hatch facilities, are equipped in such a way that several coatings are applied after a coating process. The slide bearings are to be coated with several coats and the coating materials used and the conditions related thereto require the use of several coating techniques. This relates inter alia to conveyance parameters. Existing facilities fail to meet these requirements. According to the invention, such a device comprises several aligned processing chambers. Slide bearings which are held together by positive and non-positive fit in tempered carrier bodies are displaced through said chambers comprising pretreatment, atomization and evaporation chambers using a conveyance system adapted to this process. A tempering device for the carrier bodies is connected upstream from the coating track. Corresponding inlet and outlet channels enable air-to-air conveyance.Type: GrantFiled: August 31, 2000Date of Patent: September 3, 2002Assignee: Ferderal-Mogul Wiesbaden GmbH & Co.

Patent number: 6316061Abstract: A half bearing has a backing member and at least one metallic overlay, which is applied by electron beam vapour deposition and which comprises at least one finely dispersed component in a matrix material, the atomic weight of which component is greater than that of the matrix material, wherein the concentration of the finely dispersed component (7) decreases continuously from the apex area (8) of the half bearing (1) towards the area (9) of the partial surfaces. The method is characterised in that, during the coating process, an inert gas pressure of 0.1 to 5 Pa is set in the apex area of the bearing shell.Type: GrantFiled: May 31, 2000Date of Patent: November 13, 2001Assignee: Federal-Mogul Wiesbaden GmbH & Co.

Patent number: 6273972Abstract: A composite multilayer material and a method for the production thereof are described which are suitable for bearing points subject to mixed friction, said material being corrosion-resistant and cold-formable and capable of withstanding extremely high loads. According to the method, the backing material is preheated to a temperature of 1000° C. to 1100° C., a heterogeneously developing, lead-free copper-zinc- or copper-aluminum-based bearing alloy at a temperature of from 1000° C. to 1250° C. is cast thereon, and the composite multilayer material is cooled from the casting temperature of the bearing alloy to 100° C. within 2 to 4 minutes. A metallurgical bond zone (2) is present between the bearing alloy (3) and the backing material (1), which metallurgical bond zone (2) comprises 80-95% iron and the usual impurities, the rest being copper, and is crystallised in cubic form.Type: GrantFiled: August 5, 1999Date of Patent: August 14, 2001Assignee: Federal-Mogul Wiesbaden GmbH & Co.KGInventor: Gerd Andler

Patent number: 6263575Abstract: A plain bearing overlay (3) of which exhibits properties which are markedly improved with regard to wear resistance in comparison with overlays applied by electroplating and conventional electron beam vapor deposition methods. The surface of the overlay (3) comprises round raised portions (4) and depressed portions (6), wherein, in relation to the horizontal section plane (7), the raised portions (4) cover a proportion of the surface area amounting to 30% to 50%, based on the entire surface area of the plain bearing, the section plane (7) being at a height at which the total proportion of the surface area consisting of the raised portions (4), and obtained in vertical section, is equal to the total corresponding proportion consisting of the depressed portions (6). The round raised portions exhibit a diameter D of 3 to 8 &mgr;m, in plan view, wherein, in the case of raised portions (4) and depressed portions (6) which in plan view are not circular, this value relates to the maximum diameter.Type: GrantFiled: May 31, 2000Date of Patent: July 24, 2001Assignee: Federal-Mogul Wiesbaden GmbH & Co.
