Patent number: 9096471Abstract: A layered material 1 includes two metal sheets 2,3 and one ceramic sheet 4, wherein the metal sheets 2,3 and the ceramic sheet 4 are stacked so that the ceramic sheet 4 is disposed between the two metal sheets 2,3, and then bonded together through spark plasma sintering. The difference in melting temperature between the metal sheets 2 and 3 is 140° C. or less. The layered material 1 is produced by stacking two metallic sheets 2,3 that have a difference in melting temperature of 140° C. or less and the ceramic sheet 4 so that the ceramic sheet 4 is placed between the both metal sheets 2,3, then disposing the stacked structure of the metal sheet 2,3 and the ceramic sheet 4 between a pair of electrodes in a spark plasma sintering device, and bonding the metal sheets 2,3 and the ceramic sheet 4 by applying a pulse current between the electrodes while maintaining the conduction between the electrodes.Type: GrantFiled: November 26, 2010Date of Patent: August 4, 2015Assignee: Showa Denko K.K.Inventors: Daisuke Suzuki, Shigeru Oyama, Atsushi Otaki

Patent number: 8987895Abstract: A clad material 1A for insulating substrates is provided with a Ni layer 4 made of Ni or a Ni alloy, a Ti layer 6 made of Ti or a Ti alloy and arranged on one side of the Ni layer, and a first Al layer 7 made of Al or an Al alloy and arranged on one side of the Ti layer 6 that is opposite to a side of the Ti layer 6 on which the Ni layer 4 is arranged. The Ni layer 4 and the Ti layer 6 are joined by clad rolling. A Ni—Ti series superelastic alloy layer 5 formed by alloying at least Ni of constituent elements of the Ni layer 4 and at least Ti of constituent elements of the Ti layer 6 is interposed between the Ni layer 4 and the Ti layer 6. The Ti layer 6 and the first Al layer 7 are joined by clad rolling in an adjoining manner.Type: GrantFiled: October 25, 2011Date of Patent: March 24, 2015Assignee: Showa Denko K.K.Inventors: Atsushi Otaki, Shigeru Oyama

Patent number: 8772926Abstract: The production method of a cooler includes a laminated material production step S1 and a brazing joining step. In the laminated material production step, a laminated material is formed by integrally joining a Ni layer made of Ni or a Ni alloy having an upper surface to which a member to be cooled is to be joined by soldering, a Ti layer made of Ti or a Ti alloy and arranged on a lower surface side of the Ni layer, and an Al layer made of Al or an Al alloy and arranged on a lower surface side of the Ti layer in a laminated manner. In the brazing joining step, a lower surface of the Al layer of the laminated material and a cooling surface of a cooler main body are joined by brazing.Type: GrantFiled: May 7, 2013Date of Patent: July 8, 2014Assignee: Showa Denko K.K.Inventors: Atsushi Otaki, Shigeru Oyama
