In the past, apparently little attention has been paid to the role of the physical vapor deposition treatment on the physical and mechanical properties of the ion-exchanged glass. Some recent results indicated the ion-exchanged glasses exhibited anomalous temperature dependence for stress relaxation process. With a liquid water or water vapor atmosphere, Tomozawa et al. found glass surfaces exhibited faster relaxation than the bulk at a constant temperature. Nevertheless, there are no much studies on surface modification of the ion-exchanged glasses under coatings and particle impact, particularly below the glass transition temperature.
