    摘要: It is difficult to perform surface modification by irradiating a side surface of a hole formed on an irradiated object with a low-energy-density electron beam. An irradiated object having an irradiation hole formed thereon is disposed in a vacuum chamber. A cathode electrode is arranged to face a side surface of the irradiation hole. The cathode electrode has a large number of metal projections over an entire surface of a base body, the base body facing at least the side surface of the irradiation hole. A conductive mesh is arranged between the cathode electrode and the side surface of the irradiation hole. The conductive mesh partially contacts the irradiated object and is set to have the same potential as the irradiated object.

    摘要: Disclosed is a method of manufacturing an airfoil structure. The airfoil structure includes a plurality of airfoils, a support for supporting the airfoils, and a case for covering the airfoils. Each airfoil includes an airfoil body, and an airflow generator for producing induced airflow by generating plasma. The method includes a process of forming the airflow generator that includes a first electrode forming step of forming a first electrode on the airfoil body, a dielectric layer forming step of forming a dielectric layer on the airfoil body by forming ceramic powder into a film to cover the first electrode through room temperature impact consolidation, and a second electrode forming step of forming a second electrode on a surface of the dielectric layer, such that the second electrode is electrically connected to the first electrode, and an alternating-current voltage is applied to the second electrode.
