Patent number: 9816613Abstract: A sliding element, such as a piston ring, including a substrate, base coating, and relatively thin sliding coating is provided. The base coating is typically applied to a running surface of the substrate by PVD, CVD, galvanic deposition, electrodeposition, or a thermal spray process. The sliding coating includes a polymer matrix and hard particles disposed throughout the matrix. The sliding coating is applied to the base coating when the base coating is still in its as-applied condition and has a surface roughness of at least 4.0 ?m. During use of the sliding element, the thin sliding coating acts as a sacrificial run-in layer. In addition, as the polymer matrix of the sliding coating wears away, the hard particles polish the rough surface of the base coating. Thus, polishing or lapping of the as-applied base coating prior to use of the sliding element is not required.Type: GrantFiled: January 23, 2017Date of Patent: November 14, 2017Assignee: Federal-Mogul LLCInventors: Troy Kantola, James R. Toth, Robert R. Aharonov

Patent number: 9163579Abstract: A piston and method of construction are provided. The piston includes a piston body having an upper combustion surface configured for direct exposure to combustion gases within a cylinder bore with an undercrown surface located beneath the upper combustion surface. The piston body also includes a ring belt region configured for receipt of at least one piston ring adjacent the upper combustion surface with a cooling gallery configured radially inwardly and in substantial radial alignment with the ring belt region. The piston further includes a non-stick material contained in or bonded to at least one of the undercrown surface and at least a portion of the cooling gallery, wherein the non-stick material inhibits the build-up of carbon deposits thereon.Type: GrantFiled: March 5, 2013Date of Patent: October 20, 2015Assignee: Federal-Mogul CorporationInventors: Robert R.

Patent number: 8919318Abstract: A cylinder liner (20) comprises a substrate (24) and a germanium containing coating (22), typically a diamond-like carbon (DLC) coating applied by a vapor deposition technique. The coating (22) may include a base layer (36), an intermediate layer (38), and a protective layer (40), each having a graded composition. The base layer (36) comprises, in weight percent (wt. %) of the base layer (36), 50.0 to 70.0 wt. % carbon, 30.0 to 50.0 wt. % silicon, and not greater than 20.0 wt. % germanium. The intermediate layer (38) comprises, in weight percent (wt. %) of the intermediate layer (38), 40.0 to 60.0 wt. % carbon, 15.0 to 35.0 wt. % silicon, and 15.0 to 35.0 wt. % germanium. The protective layer (40) includes, in weight percent (wt. %) of the protective layer (38), at least 90.0 wt. % carbon.Type: GrantFiled: June 11, 2012Date of Patent: December 30, 2014Assignee: Federal-Mogul CorporationInventor: Robert R.
