摘要:
A method of improving strength of a chemically-strengthened glass article comprises exposing a target surface of the glass article to an ion-exchange strengthening process, the ion-exchange strengthening process generating a chemically-induced compressive layer in the glass article. Thereafter, dynamic interfacing of the target surface of the glass article with a sheared magnetorheological fluid is performed to remove at least a portion of the chemically-induced compressive layer from the glass article, wherein the parameters of the dynamic interfacing of the glass article with the sheared magnetorheological fluid are such that a thickness of the removed portion of the chemically-induced compressive layer is less than approximately 20% of the chemically-induced compressive layer.

Methods of finishing a sheet of material, such as a glass sheet, include finishing an edge portion of the sheet of material with magnetorheological finishing. In one example, the average thickness of the sheet of material between a first face and a second face is from 50 μm to about 500 μm. In another example, the method consists essentially of a single step of finishing the edge portion of the glass sheet with magnetorheological finishing such that the entire edge portion is shaped between the first face and the second face during the a single magnetorheological finishing step.
摘要:
Methods for separating glass articles from strengthened glass substrate sheets and strengthened glass substrate sheets are provided. In one embodiment, a method includes forming at least one groove on at least one surface of the glass substrate sheet and strengthening the glass substrate sheet by a strengthening process. The groove defines the glass article and partially extends through a thickness of the glass substrate sheet. The method further includes generating an initiation defect on the groove at an initiation location to cause a through crack to self-propagate through the glass substrate sheet along the groove, thereby separating the glass article from the glass substrate sheet. In another embodiment, a strengthened glass substrate sheet includes a strengthened glass having a glass article groove and an initiation groove on a surface, the glass article groove defining a glass article.
