Patent number: 6436470Abstract: An improved method of applying a particulate material to a substrate, includes the steps of: removing impurities from a surface of the substrate; forming a coating composition having a bonding material and at least one particulate material; applying the coating composition to the substrate surface; and creating a diffusion bond between the substrate, bonding material and particulate material for generating a continuous interface between the substrate surface and particulate material such that the change in mechanical properties between the substrate and particulate material occurs in a direction normal to the plane of the substrate surface, thereby minimizing residual strain and coefficient of thermal expansion mismatch between the substrate and particulate material, the surfaces of individual particles of said particulate material being chemically wetted by the bonding material. The particulate material and the bonding material comprise a layer on the substrate surface.Type: GrantFiled: February 22, 2001Date of Patent: August 20, 2002Assignee: Penn State Research FoundationInventors: Ronald G. Iacocca, Karthik Sivaraman, Anand Lal, Randall M. German

Patent number: 6387458Abstract: A reverse painting process includes the preheating of work prior to its powder coating. By the preheating of the work, it becomes possible to form a film having a sufficiently large thickness for maintaining a satisfactorily high level of rustproofness in the boundary area between a film of the powdery paint and a film formed by electrodeposition, thus achieving drastic shortening of the time required for heating it in the fusing oven.Type: GrantFiled: August 12, 1997Date of Patent: May 14, 2002Assignee: Honda Giken Kabushiki KaishaInventors: Yukihide Yamashita, Masayuki Yamaguchi, Shirou Kamiyama, Kenichirou Mori

Patent number: 6358565Abstract: The present invention relates to a method for making a protective coating containing silicon carbide on at least a portion of the surface of a substrate made from a material with a softening temperature that is above the temperature applied to make the protective coating, where silicon is deposited on the portion of the surface of the substrate and where, under vacuum or in an inert atmosphere, the substrate is heated to a temperature above the melting point of silicon, and the silicon is brought to reaction with carbon that is contained in a porous coating. The surface of the object to be coated is initially provided with a porous carbon coating with an open porosity in a range between 40 and 95%, where said porous carbon coating is covered with a uniform coating of silicon, where the ratio in percent of mass (Ma-%) of the applied silicon to that of the carbon in the porous carbon coating is greater than 2.Type: GrantFiled: July 16, 1999Date of Patent: March 19, 2002Assignee: Deutsches Zentrum fuer Luft-und Raumfahrt E.V.Inventors: Walter Krenkel, Thilo Henke

Patent number: 6235685Abstract: A rod 1 made of superconducting oxide is soaked in a molten normal conductor 2 to join the rod 1 and the normal conductor 2, whereby a superconducting oxide current lead is prepared. As a result, a contact resistance at the interface between the superconducting oxide and the normal conductor can be reduced. Consequently, Joule's heat at a current lead having a small cross sectional area can be suppressed low, which in turn realizes the reduction of the load on a freezer and the amount of evaporated cooling solvent, with respect to a superconducting coil.Type: GrantFiled: November 15, 1999Date of Patent: May 22, 2001Assignee: International Superconductivity Technology CenterInventors: Junya Maeda, Teruo Izumi, Yuichi Imagawa, Satoshi Matsuoka, Yuh Shiohara, Shoji Tanaka, Hiroshi Okamoto
