Web16 mrt. 2016 · Glasses can be chemically strengthened through the ion exchange process, wherein smaller ions in the glass (e.g., Na +) are replaced by larger ions from a salt bath (e.g., K + ). This develops a compressive stress (CS) on the glass surface, which, in turn, improves the damage resistance of the glass. WebIon-exchanged glass waveguides: a review Abstract: Passive glass waveguides made by ion-exchange technique are potential candidates for integrated optics (IO) applications. …
Web17 mei 2016 · This suppression of dynamic fatigue characteristics of ion-exchange strengthened glass was explained by the ability of the surface compressive layer to delay the onset of slow crack growth. Bulk stresses continue to increase in magnitude while the crack is arrested in the surface compressive stress region.
