Patent number: 11174812Abstract: A sliding member capable of improving friction characteristics under an environment of a lubricant containing Mo, and a production method therefor, is provided. The sliding member contains a sliding portion formed of a metallic material having a Ti-containing thermally sprayed coating on a surface layer part of the sliding portion. The sliding member slides under the environment of the lubricant containing Mo as an additive, in which active Ti exposed on a surface by sliding accelerates decomposition reaction of the additive contained in the lubricant to form a molybdenum disulfide-containing low-friction coating having low friction on the surface of the sliding portion.Type: GrantFiled: August 20, 2019Date of Patent: November 16, 2021Assignees: TOYOTA MOTOR EAST JAPAN, INC., TOYOTA JIDOSHA KABUSHIKI KAISHA, TOCALO Co., Ltd.Inventors: Ryo Koike, Kazuyoshi Manabe, Akihiro Kanno

Provided is the cast iron material containing C and Fe as a composition, and further containing Cr as the composition in 1.0 to 3.5% in terms of mass %. The cast iron material is used in a sliding component sliding under an environment of lubricating oil to which an additive containing Mo as a constituent element, such as MoDTC, is added. Cr contained in the cast iron material promotes a decomposition reaction of the additive containing Mo added to the lubricating oil to form a film of molybdenum disulfide, the film having low friction. Thus, the fiction can be reduced.Type: ApplicationFiled: November 16, 2018Publication date: May 16, 2019Applicants: TOYOTA MOTOR EAST JAPAN, INC., TOYOTA JIDOSHA KABUSHIKI KAISHA, TPR CO., LTD., TPR INDUSTRY CO., LTD., HappyProduct Inc.Inventors: Ryo KOIKE, Atsushi Suzuki, Kazuyoshi Manabe, Kiyoyuki Kawai, Masami Horigome, Takashi Oizumi, Tetsuo Hasegawa, Katsunori Kanauchi, Mihoko Sawada, Kazue Kurihara, Koshi Adachi
