Patent number: 6623876Abstract: The invention concerns a mechanical part with abrasionproof surface characterized in that it comprises a sintered metallic body obtained from metallic powders and a laser-deposited cermet coating. The coating has a certain thickness whereof a portion is metallurgically bound with the metallic body. The laser deposit enables the sintered part to be surface-melted under the effect of the laser beam. The surface of the sintered part to be coated is therefore fused over a thickness ranging between 10 &mgr;m and 1 mm, which enables the surface pores to be closed, as is characteristic of sintered parts, thereby increasing its resistance to shocks. Moreover, the small surface coated at a given moment by the laser enables the self-hardening of the exposed part, following the beam displacement, by the heat-sink effect of the surrounding metallic volume. The resulting coating also has very low porosity owing to the complete fusion of the powders by laser.Type: GrantFiled: November 24, 1999Date of Patent: September 23, 2003Assignee: Invegyre Inc.Inventor: Paul Caron

The present invention also includes the stator honeycomb produced by the foregoing method.Type: GrantFiled: April 26, 2001Date of Patent: August 26, 2003Assignee: General Electric CompanyInventors: Thomas Tracy Wallace, Brent Ross Tholke -
Patent number: 6602615Abstract: Disclosed is a composite sliding material having a steel plate and a sintered copper alloy layer which is bonded to the steel plate. The copper alloy contains, 1.5 to 15 mass % Sn, 1.5 to 15 mass % Bi, 1.5 to 20 volume % of a solid lubricant, and balance of Cu and incidental impurities.

Nickel-Silver brazing material is used to form the matrix on the steel plate, and tungsten carbide particles of 8-10 mesh are secured within the matrix, with the hard particles of tungsten carbide partially exposed, presenting a roughened surface with angular pieces of tungsten carbide to the drilling attack.Type: GrantFiled: November 13, 2001Date of Patent: April 1, 2003Assignee: Rhino Metals, Inc.Inventor: Donald K. Suggs

Patent number: 6528182Abstract: The invention concerns a steel plate coated with a metal layer based on zinc and a zinc hydroxysulphate layer, whereof the surface density of sulphur is more than 0.5 mg/m2. The invention also concerns a method for obtaining said plate by treating a zinc coated sheet metal: either in a highly alkaline sulphate solution under polarization; or in a sulphate solution containing Zn2+ ions without polarization. The hydroxysulphate deposit brings about a pre-lubricating effect applicable to operations for forming sheet metal.Type: GrantFiled: June 25, 2001Date of Patent: March 4, 2003Assignee: SollacInventors: Alain Bello, Sylviane Wajda, Jacques Petitjean, Armand Rossi

Publication number: 20030035044Abstract: A method of producing a wear-resistant protective film for a thermal head comprises depositing a wear-resistant protective film by sputtering on a thermal head which includes a substrate, and a heat-developing layer and a pair of electrodes formed on either the substrate or a heat-regenerative layer formed thereon. A layer of the wear resistant protective film is formed under a RF larger bias and another layer without a bias or with a smaller bias. Good step coverage is obtained by the RF sputter layer of the wear-resistant and the protective film prevents the intrusion of water that can cause cracking, and the layer formed under no or smaller bias reduces internal stresses and inhibits the development of cracks due to internal stresses as well as the cracking by RF sputtering.Type: ApplicationFiled: September 30, 2002Publication date: February 20, 2003Applicant: TDK CorporationInventors: Masatoshi Nakayama, Masahiro Nakano, Tsukimi Endo

Patent number: 6521554Abstract: A wear resistant stitchbonded fabric is provided. The stitchbonded fabric includes a first yarn loosely stitchbonded into the substrate so as to substantially cover one side of the substrate. The fabric further includes a second yarn that is tightly stitchbonded into the substrate. In one embodiment, the nonwoven substrate can further contain binder fibers which are fused to adjacent fibers. Through this configuration, a fabric is produced having a tapestry-like look. The fabric can be used in many diverse applications, such as being used as an upholstery fabric.Type: GrantFiled: February 22, 2000Date of Patent: February 18, 2003Assignee: Tietex International, Ltd.Inventor: Martin Wildeman
