Abstract: Apparatus, systems and methods for improving chemical strengthening behavior in glass members are disclosed. According to one aspect, a method for processing a glass part formed using a fusion process or a float process includes annealing the glass part and then chemically strengthening the glass part. Annealing the glass part includes at least heating the glass part at a first temperature, maintaining the first temperature, and cooling the glass part to a second temperature using a controlled cooling process. Chemically strengthening the glass part includes facilitating an ion exchange between ions included in the glass part and ions included in a chemical strengthening bath.

Abstract: A method for strengthening a glass cover for an electronic device is disclosed, where the method comprises chemical strengthening in a series of stages. The stages can have a first ion exchange stage using heated solutions (melts) where larger ions are exchanged into the glass cover, and a second ion exchange stage where some of the larger ions are exchanged out from the glass cover. The region of peak compressive strength 1028 occurs at a distance below the treated surface. Optionally, the glass cover can have its strength increased by forming its edges with a predetermined curved or chamfered geometry. In one embodiment, the glass member can pertain to a glass cover for a housing for an electronic device. The glass cover can be provided over or integrated with a display, such as Liquid Crystal Display (LCD) display.
