METHOD OF STRENGTHENING GLASS BY PLASMA INDUCED ION EXCHANGES, AND ARTICLES MADE ACCORDING TO THE SAME

Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

Method of ion beam milling a glass substrate prior to depositing a coating system thereon, and corresponding system for carrying out the same

A glass substrate is ion beam milled in order to smoothen the same and/or reduce or remove nano-cracks in the substrate surface before a coating system (e.g., diamond-like carbon (DLC) inclusive coating system) is deposited thereon. It has been found that such ion beam milling of the substrate prior to deposition of the coating system improves adherence of the coating system to the underlying milled substrate. Moreover, it has surprisingly been found that such ion beam milling of the substrate results in a more scratch resistant coated article when a DLC inclusive coating system is thereafter ion beam deposited on the milled substrate. Amounts sodium (Na) may also be reduced at the surface of the substrate by such milling.

Method for manufacturing an article comprising a refractory a dielectric body

A refractory dielectric body is heated with a plasma fireball at conditions which do not result in substantial removal of a surface portion of the body, yet which are sufficient to reduce both surface and bulk impurities.
