Publication number: 20230313693Abstract: A rotor assembly component which is a component of a gas turbine engine is provided with a rotor assembly component body made from a metal, and a hard particle layer including a mass of hard particles and a matrix material, with the hard particles being made from a material harder than a material forming the rotor assembly component body. The matrix material is made solely from the material forming the rotor assembly component body. The hard particle layer is supported directly on a surface of the rotor assembly component body.Type: ApplicationFiled: May 18, 2023Publication date: October 5, 2023Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Yoshikatsu SATO, Ryo MORIHASHI, Toshiro TSUJI, Hiroshi TAKI, Kazushige FUJIMITSU

Patent number: 11674472Abstract: A method of improving corrosion resistance of a cylinder cover including a port that is an intake port or an exhaust port. The cylinder cover is configured such that an annular cooling water passage is formed between an inner peripheral surface of the port and a valve seat ring when the valve seat ring is inserted in the port. The method includes forming a weld overlay layer on each of sealed regions of the inner peripheral surface of the port by laser metal deposition using a welding material made of a nickel-based alloy, a copper alloy, stainless steel, or a titanium alloy, the sealed regions being positioned at both sides of the cooling water passage, respectively.Type: GrantFiled: February 13, 2020Date of Patent: June 13, 2023Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Daichi Kubo, Yuto Sakane, Tomohiro Ueno, Ryo Morihashi, Hayato Iwasaki, Yuji Kamei, Hideaki Kurokawa, Yoshishige Sakai, Takayuki Imai

Patent number: 11420291Abstract: A projection forming method forming a projection on the surface of a work and includes: forming a first bank by LMD such that the first bank surrounds a projection forming region on the surface of the work; forming a first layer on the projection forming region by the LMD such that the first layer covers the first bank; laminating at least one first height raising layer on the first layer by the LMD; forming a second bank by the LMD along a peripheral edge of the at least one first height raising layer; forming an intermediate base layer on the at least one first height raising layer by the LMD such that the intermediate base layer covers the second bank; and laminating at least one second height raising layer on the intermediate base layer by the LMD.Type: GrantFiled: December 21, 2017Date of Patent: August 23, 2022Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Yuya Gyotoku, Ryo Morihashi, Yuto Sakane, Hiroka Fujita, Yuki Ono, Hayato Iwasaki

Patent number: 10603869Abstract: A laminated structure has a first layer formed from a fiber reinforced plastic, a second layer formed from a fiber reinforced plastic and arranged opposed to the first layer, a first core layer formed from a first resin foam and arranged between the first layer and the second layer, and a second core layer formed from a second resin foam and arranged between the first core later and the second layer. The first resin foam has a higher flame resistance than the second resin foam. A laminated structure having flame resistance and high strength enough to endure a bird strike or the like at the same time can be manufactured at relatively low manufacturing cost.Type: GrantFiled: December 19, 2014Date of Patent: March 31, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Ryo Morihashi, Takeshi Hasegawa, Yosuke Tsumura, Takeshi Takagi
