摘要:
A pattern forming device includes a plurality of tanks, and a power supply device. Each of the tanks has an open end having the same shape as a profile shape of a corresponding one of regions of a surface of a workpiece, in which different types of films are to be formed, and stores a corresponding one of electrodeposition solutions used to form the different types of films in a state where the open end is in contact with the surface. The power supply device applies a predetermined voltage to between the workpiece that serves as a first electrode, and each one of second electrodes in the tanks.
摘要:
A rolling bearing includes an inner ring (10), an outer ring (20), and a plurality of rolling elements (31). A large number of inside dimples (16) in which a liquid lubricant is retained and a large number of outside dimples (18) in which a solid lubricant is retained are formed in at least one of an inner ring raceway surface (12) and an outer ring raceway surface (22). The inside dimples (16) are formed in a contact region (13, 23) at which the raceway surface (12, 22) contacts the rolling elements (31) or in a section of each non-contact region (14, 24), the section being close to the contact region (13, 23). The outside dimples (18) are formed outside a portion in which the inside dimples (16) are formed.
摘要:
A DLC-coated member (100) has a base (200), an intermediate layer (300) that covers the surface of the base (200), and a DLC film (400) that covers the surface of the intermediate layer (300). The intermediate layer (300) has a five-layer structure, constituted of a first intermediate layer (301), a second intermediate layer (302), a third intermediate layer (303), a fourth intermediate layer (304), and a fifth intermediate layer (305). The five layers (301 to 305) are made of DLC to which Si has been added. Among the layers (301 to 305), the Si concentration in the first intermediate layer (301) is the highest, and that in the fifth intermediate layer (305) is the second highest. The Si concentrations in the second intermediate layer (302), third intermediate layer (303), and fourth intermediate layer (304) are lower than those in the first intermediate layer (301) and fifth intermediate layer (305).
摘要:
A sliding member is integrally formed of fluororesin as a whole, and a sliding surface to be slid with a slid member is made hydrophilic. A manufacturing method includes a step of exposing the sliding surface 2 of the sliding member 1 to water plasma 7 generated by Ar gas and vaporized water as raw materials and making the sliding surface 2 hydrophilic.
摘要:
A DLC film (121) is formed on a surface of a first shaft (10) by generating cylindrical plasma (3a) in a vacuum deposition chamber (30), supplying material gas into the vacuum deposition chamber (30), and applying pulse voltage to a first shaft (10) as a coated body. A jig (41) that shields a yoke (11) is attached to the yoke (11) as an uncoated part where the DLC film (121) of the first shaft (10) is not formed with separation spacing over a spline fitting part (12) as a coated part where the DLC film (121) is to be formed for preventing decrease of the hardness of the DLC film (121) in the spline fitting part (12).
摘要:
A production method of a coated member (20) is performed in the following way. First, a diamond-like carbon film deposition process in which the diamond-like carbon film (21) is formed on a surface of the base material (4) by generating plasma by applying voltage to the base material (4) in a processing chamber (3) that stores the base material (4), while evacuating the processing chamber (3) and introducing feedstock gas that contains at least a carbon compound into the processing chamber (3). After this, a hydrogenation process in which the deposited diamond-like carbon film (21) is hydrogenated using hydrogen gas by stopping the voltage application and introducing hydrogen gas inducted instead of the feedstock gas, while the evacuation is being continued.
摘要:
An oil pump has: a base part (1) having a working chamber (11); and a rotor (3) provided rotatably in the working chamber (11). The base part (1) is configured by a plurality of split bodies (13,18). At least one split body (18) (rear housing) out of the plurality of split bodies (13,18) is made of aluminum alloy, and on which an opposed sliding surface (180) made of a ceramic film (185) is formed. The ceramic film (185) of the opposed sliding surface (180) has a hardness of approximately Hv 500 to 1100 and a surface roughness of approximately 2 to 8 micrometers, and contains α - alumina and zirconia.
