Abstract:
[Task] It is to provide a fiber-reinforced resin structure having improved surface properties and reinforced with carbon fibers or glass fibers while keeping lightweight properties.[Solution] A fiber-reinforced resin structure is constructed by forming a thermal sprayed coating composed mainly of boron carbide on a fiber-reinforced plastic substrate as a top coating.
Abstract:
An insulated bearing includes an outer ring, an inner ring, and a plurality of rolling elements. At least one of the outer ring and an inner ring is made of metal, the plurality of rolling elements are provided between the outer ring and the inner ring, so as to be freely rolled, and at least one of the outer ring and an inner ring is coated with an insulating layer. The insulating layer is formed of a mixture in which silicon carbide and/or aluminum nitride as an additive are/is dispersed in aluminum oxide as a base matrix. The content of the additive is 1 to 40 mass % with respect to the total amount of the mixture.
Abstract:
A thermal spray powder is provided that contains, as constituent elements, a first element selected from W and Mo; a second element selected from Co, Ni, and Fe; a third element selected from C and B; and a fourth element selected from Al and Mg. The amount of the second element in the thermal spray powder is 20% by mole or greater. The mole ratio of the fourth element to the second element in the thermal spray powder is 0.05 or greater and 0.5 or less. The thermal spray powder has a crystal phase containing Co, Ni, or Fe; W; and C or a crystal phase containing Co, Ni, or Fe; W or Mo; and B. In an X-ray diffraction spectrum of the thermal spray powder, the peak intensity attributed to Co, Ni, or Fe is at most 0.1 times the largest peak intensity in the same X-ray diffraction spectrum.
Abstract:
A plasma processing apparatus includes a processing chamber; a lower electrode serving as a mounting table for mounting thereon a target object; and an upper electrode or an antenna electrode provided to be opposite to the lower electrode. The apparatus further includes a gas supply source for introducing a gas including a halogen-containing gas and an oxygen gas into the processing chamber and a high frequency power supply for applying a high frequency power for generating plasma to at least one of the upper electrode, the antenna electrode, or the lower electrode. Among inner surfaces of the processing chamber which are exposed to the plasma, at least a part of or all of the surfaces between a mounting position of the target object and the upper electrode, or the antenna electrode; or at least a part of or all of the surfaces of the upper electrode or the antenna electrode are coated with a fluorinated compound.
Abstract:
A spray coated member having an excellent resistance to plasma erosion is produced by irradiating an electron beam to an outermost surface layer portion of a ceramic spray coated portion covering a surface of a substrate to form an electron beam irradiated layer.

Abstract:
A member is obtained by forming a Y2O3 black spray coating on a surface of a substrate or covering the surface of the substrate with a Y2O3 black spray coating through an undercoat or a middle layer. This coating has good heat characteristics and is good in the resistance to damaging through a high hardness. The Y2O3 black spray coating is produced by subjecting white Y2O3 powdery material to a plasma spraying in an inert gas atmosphere containing substantially no oxygen or by forming a Y2O3 white spray coating and then irradiating an electron beam or a laser beam to this coating to melt at least a part of the white coating under heating to thereby smoothen denseness and blacken the surface of the coating.

Abstract:
A ceramic spray-coated member capable of surely controlling adhesion and detachment of water is produced by spraying a given ceramic onto a surface of a base material, in which an organic matter adsorbed on a surface of the ceramic spray-coated member is removed and the surface of the ceramic spray-coated member is stabilized by chemically bonding to water.
