“…Yet, in the presence of humidity, significant differences in crack initiation stress and fracture stress between annealed and acid‐leached SLS were observed. These results support the hypothesis which considers the transport of water through the leached layer to rationalize why acid‐leaching surface treatments can increase the apparent fracture strength of SLS glass in the presence of water 37 …”

“…In general, acid leaching treatments result in a silica‐rich surface layer with increased amounts of hydrous species (Si‐OH and molecular water) and with an increased void volume fraction 21,22,37,47,48 . Water can easily absorb into and desorb from this newly formed porous surface layer 21,48 .…”

“…Water can easily absorb into and desorb from this newly formed porous surface layer 21,48 . Previous work showed that acid‐leaching (in pH 1, 90 ºC) SLS for 24‐hours results in a leached layer thickness of ~120 nm which increases to ~150 nm after 72‐hour of acid‐leaching 37 …”

Water or acid soaking surface treatments have been shown to increase the mechanical strength of soda‐lime silicate (SLS) glasses. This increase in strength has traditionally been attributed to effects related to residual stress or changes in fracture resistance. In this work, we report experimental data that cannot be explained based on the existing knowledge of glass surface mechanics. In dry environments, annealed and acid‐leached SLS surfaces have comparable crack initiation stress and fracture stress as measured by Hertzian indentation and biaxial bending tests, respectively. Yet, in the presence of humidity, acid‐leached surfaces have higher failure stress than the annealed surfaces. This apparent enhancement in the crack resistance of the acid‐leached surface of SLS glass in humid environments supports the hypothesis that acid‐leached surface chemistry can lower the transport kinetics of molecular water to critical flaws.

This work aims to explore the interaction between water and ion-exchanged aluminosilicate glass. The surface mechanical properties of ion-exchanged glasses after different hydration durations are investigated. The compressive stress and depth of stress layer are determined with a surface stress meter on the basis of photo-elasticity theory. The hardness and Young’s modulus are tested through nanoindentation. Infrared spectroscopy is used to determine the variation in surface structures of the glass samples. The results show that hydration has obvious effects on the hardness and Young’s modulus of the raw and ion-exchanged glasses. The hardness and Young’s modulus decrease to different extents after different hydration times, and the Young’s modulus shows some recovery with the prolonging of hydration time. The ion-exchanged glasses are more resistant to hydration. The tin side is more resistant to hydration than the air side. The results are expected to serve as reference for better understanding the hydration process of ion-exchanged glass.

“…This method of strengthening glass is somewhat more expensive, but it allows high compressive stresses to be obtained and allows the processing of glass of thinner thickness. Another method of chemical strengthening of glass is associated with the deposition of thin films of polyorganosiloxanes or silicic acid polymers on its surface, which reduce the wedging effect of moisture in glass microcracks [7,8].…”
