Abstract
Official abstract text for this publication.
Disclosed herein are methods for strengthening glass articles having strength-limiting surface flaws, together with strengthened glass articles produced by such methods, and electronic devices incorporating the strengthened glass articles. The methods generally involve contacting the glass articles with a substantially fluoride-free aqueous acidic treating medium for a time at least sufficient to increase the rupture failure points of the glass articles.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: providing a glass article, comprising: strength-limiting surface flaws having a first shape; and a first rupture failure point; and contacting the glass article with a treating medium to produce a strengthened glass article comprising a second rupture failure point, wherein at least a subset of the strength-limiting surface flaws of the strengthened glass article have a second shape, the contacting occurs for a time at least…
