摘要:
A plasma chemical vapor deposition device includes a chamber (12), a first conductor (20) having an elongated shape, a second conductor (30) having a tubular shape, a high-frequency output device (45), and a direct-current power supply (46). A first connecting portion (23) of the first conductor (20) with the high-frequency output device (45) and a second connecting portion (24) of the first conductor (20) with the direct-current power supply (46) are both placed outside the chamber (12). A distance from one end of the first conductor (20) to the first connecting portion (23) is shorter than a distance from the one end of the first conductor (20) to the second connecting portion (24). An impedance change portion (25) is provided between the first connecting portion (23) and the second connecting portion (24) in the first conductor (20), the impedance change portion having an impedance different from an impedance between the one end of the first conductor (20) and the first connecting portion (23).
摘要:
A spray coating film has a first spray coating film formed on a surface of an aluminum substrate and a second spray coating film formed on a surface of the first spray coating film. In the first spray coating film, an inorganic material with a layered crystalline structure is dispersed in a Ni-based alloy material, and an area ratio of the inorganic material is in a range from 40% to 80% relative to the sectional area of the first spray coating film. The second spray coating film is a porous film composed of ZrO 2 -SiO 2 based ceramic containing 30% to 50% by mass of SiO 2 , and the second spray coating film has an area ratio of pores of 30% to 80% relative to the sectional area of the second spray coating film.

摘要:
A film forming method for a metal film (F) includes steps of, after a substrate material (B) is mounted on a mounting table (40), forming the metal film (F) on a surface of the substrate material (B) with a plating solution (L) brought into contact with the substrate material (B) through an electrolyte membrane (13), and with the plating solution (L) sealed, separating the electrolyte membrane (13) from the substrate material (B) by moving at least one of the mounting table (40) and a container (15) in a direction away from the other. The plating solution (L) contained in the container (15) is circulated through a circulation path (50) outside the container (15), before or during the film forming step. A circulation path (50) is blocked and the plating solution (L) in the container (15) is sealed, before this separating step.

A manufacturing method for a metal member includes irradiating a first region of a surface of the base material (11), the surface having at least any one of Cu, Al, Sn, Ti, and Fe, as a main component, with a laser beam to melt the first region; generating metal particles from a vapor or plasma of a metal released to a predetermined atmosphere by melting the surface of the base material (11) in the first region, and depositing the metal particles in the first region; irradiating a second region adjacent to the first region with a laser beam to melt the second region; and generating metal particles from a vapor or plasma of a metal released to a predetermined atmosphere by melting the surface of the base material (11) in the second region, and depositing the metal particles in each of the first region and the second region.
摘要:
A PCVD apparatus includes a waveguide member which supports the workpiece with a portion of the waveguide member positioned in a reactor and causes microwaves output from a high-frequency output device to propagate to the workpiece. In a process of gradually increasing an intensity of the microwaves propagating to the workpiece through the waveguide member from "0", the intensity (SMW) of the microwaves output from the high-frequency output device when step-up of a bias current (BA) of the workpiece occurs is referred to as a first intensity (SMW1), and in a process of gradually increasing the intensity (SMW) of the microwaves from the first intensity (SMW1), the intensity (SMW) of the microwaves when step-up of the bias current (BA) occurs again is referred to as a second intensity (SMW2). During film formation, the microwaves having an intensity (SMW) of higher than the first intensity (SMW1) and lower than the second intensity (SMW2) are output from the high-frequency output device.
