ABSTRACT:
A method and an apparatus for the ion implantation of spherical surfaces are disclosed. The method essentially includes the provision of a fixture by which a plurality of spherical workpieces are presented to a large area ion beam in a way that their entire respective spherical surfaces are uniformly ion implanted to improve their surface characteristics. The fixture basically includes a solid disc mounted for motion about two axes normal to each other, a plurality of cages formed in a first surface of the disc loosely to accommodate therein a plurality of spherical workpieces, cooling means disposed on a second surface of the disc, and a cover plate and/or mask mounted on the first surface of the disc and provided with a plurality of apertures concentric with the plurality of cages formed in the disc.
