Patent number: 11788191Abstract: A sliding member includes, on a surface of a metal substrate, a surface-treated layer including a zinc-electroplated layer, a chemical conversion-treated layer, and a topcoat layer sequentially stacked on the metal substrate. The chemical conversion-treated layer includes chromium and oxygen. The topcoat layer includes at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin. A method of manufacturing the sliding member includes a step of forming, on a surface of the chemical conversion-treated layer, the topcoat layer including at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin.Type: GrantFiled: March 3, 2017Date of Patent: October 17, 2023Assignee: NISSAN MOTOR CO., LTD.Inventors: Satoshi Watanabe, Soichiro Sugawara, Ikuo Konno

Patent number: 11248300Abstract: The present invention is to provide a chrome-plated part having a corrosion resistance in normal and specific circumstances and not requiring additional treatments after chrome plating, and to provide a manufacturing method of such a chrome-plated part. The chrome-plated part 1 includes: a substrate 2; a bright nickel plating layer 5b formed over the substrate 2; a noble potential nickel plating layer 5a formed on the bright nickel plating layer 5b. An electric potential difference between the bright nickel plating layer 5b and the noble potential nickel plating layer 5a is within a range from 40 mV to 150 mV. The chrome-plated part 1 further includes: a trivalent chrome plating layer 6 formed on the noble potential nickel plating layer 5a and having at least any one of a microporous structure and a microcrack structure.Type: GrantFiled: March 4, 2019Date of Patent: February 15, 2022Assignees: NISSAN MOTOR CO., LTD., ATOTECH DEUTSCHLAND GMBHInventors: Soichiro Sugawara, Hiroshi Sakai, Philip Hartmann

Patent number: 9650722Abstract: An nickel plating layer (5a) intended for corrosion current distribution is formed over a body (2), and a 0.05 to 2.5 micrometers thick surface chrome plating layer (6) made of trivalent chromium is formed on the surface thereof using basic chromium sulfate as a source of metal. Further on the same, a not less than 7 nm thick chromium compound film (7) is formed by cathode acidic electrolytic chromatin. The corrosion distribution nickel plating layer (5a) has a function of forming a microporous structure, a microcrack structure, or the both of the same in the surface chrome plating layer (6).Type: GrantFiled: June 3, 2014Date of Patent: May 16, 2017Assignees: NISSAN MOTOR CO., LTD., ATOTECH DEUTSCHLAND GMBHInventors: Soichiro Sugawara, Hiroaki Koyasu, Hiroshi Sakai, Jens-Eric Geissler, Grant Keers

Publication number: 20130130056Abstract: The present invention relates to a corrosion-protective composition containing a wax, an unsubstituted or substituted polyaniline in a doped form and a liquid paraffin, and articles comprising the composition applied on a substrate. It also relates to a process for manufacturing the composition, wherein i) a first dispersion of a polyaniline in a doped form is prepared; and ii) the first dispersion of the polyaniline is combined with a wax component to sufficiently disperse the polyaniline therein, and to the use of the composition as a single layer coating for the protection against corrosion of a substrate in need thereof.Type: ApplicationFiled: March 21, 2011Publication date: May 23, 2013Applicants: ENTHONE INC., NISSAN MOTOR CO., LTD.Inventors: Yasuhiro Kimura, Hideaki Yaegashi, Shinji Matsuda, Bernhard Wessling, Jörg Posdorfer, Monika Schwarzenberg, Stephan Nissen, Soichiro Sugawara
