  • Patent number: 6478876
    Abstract: There is provided a making method of a coated body by using ion plating. A melt and evaporating source housed in an evaporation container disposed above a subject to be coated in a vacuum container, is heated. The melt and evaporating source is evaporated through a number of fine evaporation holes formed in an evaporation face formed by the bottom of the evaporation container, yet preventing the melt and evaporating source from dropping. The evaporated particles from the melt and evaporating source are ionized with the use of plasma generated between the evaporation container and the subject to be coated. From above, the surface of the subject to be coated is coated with the ionized evaporated-particles, causing the ionized evaporated-particles to adhere to the surface of the subject to be coated, thus forming a coating film thereon.
