Dynamic fatigue characteristics of the as-received glass, without ion-exchange treatment, were also measured and simulated for comparison. Citing Literature. Volume 99, Issue 8. August 2016. Pages 2645-2654. Web10 apr. 2024 · However, if the ion-exchange process continues for a bulk glass, the surface compressive stress will increase, while the tensile stress inside the glass will rapidly increase. Additionally, a complete diffusion throughout the thickness could create severe internal-compressive stress, resulting in failure of the material ( Shan et al., 2024 ; … 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. The magnitude and depth of the … batang duri
