  • Method and apparatus for an anodic treatment
    Patent number: 7396439
    Abstract: A method and apparatus for anodizing a component. The component is placed in a container having first and second seal members that seal an annular surface of the component to be anodized. The first and second seal members, the annular surface of the component, and an inner surface of the container form a reaction chamber that holds a reaction medium therein. The reaction medium is supplied to the reaction chamber through a supply passage formed in the container. The reaction medium is drained from the reaction chamber through a drain passage formed in the container.
    Type: Grant
    Filed: June 4, 2004
    Date of Patent: July 8, 2008

  • Method and apparatus for an anodic treatment
    Patent number: 6814851
    Abstract: A method and apparatus for anodizing a component. The component is placed in a container having a supply port, a drain port and a supply passage. The supply passage faced on a surface of the component to be anodized. A reaction medium is supplied from the supply port to the drain port. An electric current is supplied from an electrode provided on the drain port side of the surface. The apparatus prevents any hydrogen gas created by the electrode from recirculating to the surface of the component.
