摘要： PROBLEM TO BE SOLVED: To provide a preform for a metal-based composite material of porous structure by replacing part of a heat-resistant fiber by inorganic particles so that a molten metal matrix can be easily impregnated. SOLUTION: Heat-resistant fibers are divided into smaller diameter inorganic fibers of 2-5 μm mean fiber diameter and of 10-200 μm mean fiber length and larger diameter inorganic fibers of 4-20 μm mean fiber diameter and 10-200 μm mean fiber length, inorganic particles of 1-50 μm mean grain size are dispersed in water together with a binder, placed in a mold, and dehydrated under reduced pressure. The inorganic particles are mainly captured by the smaller diameter inorganic fibers and are dispersed to prevent the inorganic particles from being densely filled in cavities of the larger diameter inorganic fibers. A preform for a metal-based composite material of porous structure is thus obtained in which formability by dehydration under reduced pressure is improved. A fiber-reinforced metal can be obtained from this porous structure in which the molten metal matrix can be easily impregnated and in which the abrasion resistance is improved by the inorganic particles.

摘要： PROBLEM TO BE SOLVED: To obtain a valve which has sufficient hardness, and is superior in the practical use and productivity, by using titanium alloy as a material of a valve for an internal combustion engine, and forming a chrome nitride film on at least a shaft sliding part by a PVD method. SOLUTION: A valve 31 for an internal combustion engine comprises a valve part 31a, a stem (shaft sliding part) 31b, and a shaft-end part 31c, and an abrasion resisting chip is welded on the shaft-end part 31c as needed. On this occasion, titanium alloy is used as a material of the valve 31, and a chrome nitride (CrN) film of 3μm thickness and about 1000HV hardness, is formed on the surface by a PVD method (ion plating method). Whereby the evaporation speed is higher than the oxidation treatment, the adhesion is improved, the film thickness can be increased, and the practical use and the productivity can be improved. On the abrasion resistance, the abrasion can be reduced in comparison with that formed by the oxidation treatment even after the internal combustion engine is driven for a specific time under a specific test condition, that is, the durability can be improved.

摘要： PURPOSE:To carry out the proper test by forming each lubricating oil feeding hole on a supporting part side in the test part shift direction and the shoulder direction in the supporting part and on a test part side on the opposed side to the test part shift direction in the test part, and preventing the lubricating oil feed shortage in the supporting part and the test part. CONSTITUTION:Thermocouples 5, 6, and 7 are installed toward the top edge parts of an upper side test part la and supporting parts 2a and 3a, and lubricating oil feeding holes 9 and 10 for feeding the lubricating oil to the top edge part are formed at the supporting parts 2a and 3a. Further, a lubricating oil feeding hole 8 is formed in the test part 1b on the downward sides of the test parts 1a and 1b. As for a test device in the ordinary mode, a rotary shaft 4 is pushed down by the downward shift of the test parts 1a and 1b in test, and the rotary shaft 4 is press-attached with the test part 1a on the upper side in the test parts 1a and 1b, while press-attached with the supporting parts 2b and 3b on the underside in the supporting parts 2a, 2b and 3a, 3b and lubricating oil is supplied from the test part 1b side and the supporting parts 2a and 3a sides which are not press-attached, and the correct temperature measurement can be carried out, preventing the supply of lubricating oil from being obstructed.

摘要： PROBLEM TO BE SOLVED: To manufacture a sliding part having high abrasion resistance and high strength by an easy machining. SOLUTION: Induction hardening is applied to a part excluding the periphery of the opening part 135 of an oil hole 130 on the surface of a sliding part 120. Therefore, induction hardening is not applied to an oil hole inside 137, the lowering of the strength of the oil hole 130 is prevented, and a boundary 145 between a part 140 that induction hardening is applied to and a part 150 that induction hardening is not applied to is formed on the surface of the sliding part 120 of a rotor that easily secures surface strength. Thereby, the boundary 145 is not formed in the oil hole inside 137, and tensile internal stress caused by the oil hole inside 137 is not also generated in the oil hole inside 137.
