Abstract

Acoustical properties of surface layers of the industrial optical glass K8 modified by a low temperature ion exchange. It is shown that alteration of both composition and diffusion stresses of ion-exchange layers influence velocity alteration of the Rayleigh surface ultrasonic waves. The ion exchange processes investigation was conducted by an optical method simultaneously. It is shown that the data obtained by both methods correlate and acoustical methods of the ion exchange layers study are more efficient than optical methods in a case of long time and high temperature of the ion exchange. Volume ultrasonic waves velocity measurements were used for a study of mechanical stresses arising in the glass volume due to the ion exchange. It is marked out that acoustical methods can be used as nondestructive methods of the ion exchange processes control.
