a film having a function such as antireflection, impact failure prevention, electromagnetic wave shielding, near infrared ray shielding or color tone correction may be applied in some cases. Some process might give rise to the structure modification and stress relaxation which will reduce the strength of the ion-exchanged glasses. The high temperature and particle impact process is an enormous challenge for the preservation of stress of the ion-exchanged glasses. Therefore, to investigate the surface structure modification of the ion-exchanged glasses during deposition of coatings is an important issue.
