Effect of Electrolyte pH on Crack Propagation in Glass.
Abstract
Crack velocity studies were conducted in various acids, bases and neutral solutions using the double cantilever beam techniques. Results are explained in terms of crack tip pH, which is controlled by the electrolyte at low crack velocities and by the glass composition at high crack velocities. The crack velocity data are consistent with the known dependence of strength on pH for soda-lime silicate glass. Results also suggest that the slope of the universal fatigue curve should depend on surface pH. (Author)
