The control process includes: detecting a light from an aperture 5b of the side of a main body 5 of a furnace through a condensing lens system 3 during the plasma nitriding operation to determine the excited state of the plasma; guiding the detected light to an emission spectroscopy photometer 4 through an optical fiber 19; condensing the detected light with a condensing unit 19a; obtaining the spectrum of the light through a monochromator 17; detecting the spectrum with an ICCD detecting device 18 provided with a gate; and informing the intensity of the emission spectrum to a controller 20 through a signal line 21. The controller 20 has an interface 23 and a personal computer 22. The personal computer 22 calculates the intensity of the emission spectrum, compares the intensity with the preset intensity which has been set in an operating panel 25, and outputs the control signal corresponding to the difference between the intensities, to the plasma power source 8.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a metallic glass compact which constitutes a powder magnetic core and can enhance the strength. SOLUTION: The method for manufacturing the metallic glass compact includes the steps of: heating the substrate particles each containing metallic glass as a main constituent while pressurizing them, and sintering a particulates body of the substrate particles. The sintering step can be divided into two stages. The first stage includes pressurizing the substrate particles so that the density of the particulates body becomes less than 90% of true density while reducing a ratio of voids among the substrate particles which constitute the particulates body, when heating the substrate particles to a temperature lower than the glass transition temperature of the metallic glass. Thereby, the density of the particulates body is enhanced. The subsequent second stage includes pressurizing the substrate particles under the condition that a distortion-varying rate (%/°C) of the particulates body with respect to the unit temperature is larger than that in the first stage, while further heating the particulates body in a range of the Tg or higher but lower than the Tx of the metallic glass.

摘要： PROBLEM TO BE SOLVED: To provide a transition metal nitride containing a low oxygen content and a high nitrogen content. SOLUTION: A base material comprising a stainless steel is subjected to gas nitriding to form a transition metal nitride on a surface layer part of the base material. A transition metal nitride layer containing the high oxygen content formed by the gas nitriding is removed by applying surface treatment to the surface part of the surface layer using a phosphoric acid-based solution or a solution containing a phosphoric acid and a fluoride-based solution. Thus, the transition metal nitride layer containing the low oxygen content and high nitrogen content is left behind on the surface of the base material. Since the transition metal nitride contains the low oxygen content and high nitrogen content, it has excellent conductivity. COPYRIGHT: (C)2008,JPO&INPIT
