Methods for improving the strength of glass substrates

摘要

Methods for improving the strength of glass substrates are described. One such method for strengthening a glass disk substrate for a storage device includes immersing at least a portion of the glass substrate in a solution, the solution including a solvent and a coating material selected from the group consisting of NaOH, KOH, and KNO3, removing the glass substrate from the solution, allowing the solvent to evaporate from the glass substrate, and heating the glass substrate at a preselected temperature for a preselected duration, where the preselected temperature is sufficient to substantially melt the coating material and is less than a transition temperature of the glass substrate.

1. A method for strengthening a glass disk substrate for a storage device, the method comprising:
immersing at least a portion of the glass substrate in a solution, the solution consisting of a solvent and a coating material consisting of NaOH; removing the glass substrate from the solution; allowing the solvent to evaporate from the glass substrate; and heating the coating material on the glass substrate at a preselected temperature for a preselected duration, wherein the preselected temperature is sufficient to substantially melt the coating material and is less than a transition temperature of the glass substrate.
