Abstract: PURPOSE:To easily take out a hydrogen peroxide decomposition catalyst from a solution after treating hydrogen peroxide in the solution without contaminating the solution. CONSTITUTION:The catalyst for decomposing hydrogen peroxide in the solution containing hydrogen peroxide is composed of a carrier made of a material insoluble in the solution and an iron phthalocyanine complex supported on the carrier. The catalyst is easily taken out from the solution after decomposition treating hydrogen peroxide in the solution without contaminating the solution. The catalyst is produced by mixing the iron phthalocyanine complex with a solution made by dissolving the carrier in a solvent and allowing the mixture to stand at room temp. or heating the mixture to remove the solvent.

Abstract: PURPOSE:To improve abrasion resistance property of a whole valve lifter by respectively instituting specific values for hardness of Fe-C series metal spray layer of the upper and lower end parts of the valve lifter in a valve system and porosity of Fe-C series metal spray layer of the center part. CONSTITUTION:Fe-C series metal spray layer is formed on the outer circumferential surface of a valve lifter body 1 made of aluminum alloy for an automobile engine or the like. In this case, as an abrasion resistance property is required at the upper part B and the lower end part C, hardness of the metal spray layer 2 is instituted at Hv 400-450, and the abrasion resistance property of the metal spray layer 2 itself is insured without increase of attacking property to the opponent (abrasion of inner surface of a guide hole). And the metal spray layer 3 of the center part A is formed so as to have blow holes impregnating lubricating oil, and as oil impregnation is not sufficient at porosity under 5% and the metal spray layer is stripped off at grinding outer surface over 10%, porosity is instituted at 5-10%. Thus, abrasion resistance property of the whole valve lifter can be improved.

Abstract: PURPOSE:To reduce the occurrence of vibration due to the generation of a heat spot by providing a thermal conductive layer having a coefficient of thermal conductivity larger than that of a heat insulating layer on each heat insulating layer disposed on both sides of a disc metallic main body and making the surface of each thermal conductive layer as a friction surface. CONSTITUTION:A main body 12 of a disc rotor 10 is cast by gray cast iron, and a heat-insulating layer 22 composed of chromium oxide is formed on both side faces of flange portion 16. A thermal conductive layer 24 composed of chrome, carbon and copper is formed on the heat insulating layer 22 by plasma flame spraying and finished by grinding. Accordingly, the frictional heat generated on friction surfaces 26, 28 is intercepted by the heat insulating layer 22, so that as the frictional heat is hardly transmitted to the main body, a temperature rise of the main body 12 is small so as to decrease partial temperature difference depending on the existence/absence of a vent hole 20 and to reduce the occurrence of a heat spot.

Abstract: PURPOSE:To prevent occurrence of nonformed parts to a hard film and also to prevent occurrence of flaws such as crack, fracturing, etc., by previously chilling the surface of a cast iron and then by forming a hard film at the time of forming a hard film of TiC, TiN, etc., on the surface of a cast iron so as to improve wear resistance. CONSTITUTION:In order to improve wear resistance at least in a part of the surface of machine parts made of cast iron, a layer of hard ceramics such as TiC, TiN, etc., is formed by a CVD or PVD method. At this time, cracking and fracturing occur to the hard ceramic layer when the cast iron it self, as a substrate, is soft and, moreover, there are cases where local nonformation of hard ceramic layer occurs to the graphite part at the surface of the cast iron. For the purpose of removing the above defects, the required part of the cast iron 1 is previously subjected to remelting by means of laser, electron beam, plasma arc, etc., and the to solidification by rapid cooling to undergo formation of a chilled layer 2, on which the hard ceramic layer 3 of TiC, TiN, etc., is formed by means of an ion plating method, a plasma CVD method, etc.
