Acoustic wave devices have been used to study atmospheric and aqueous corrosion of thin metal films. By monitoring the change in propagation velocity of a surface acoustic wave (SAW), atmospheric corrosion by gases can be recorded. Sulfidation of copper and inhibition of the sulfidation process by organic inhibitors has been studied to demonstrate the extreme mass sensitivity of the SAW devices. By exciting the same substrate at a different frequency, a shear horizontal acoustic plate mode (SH-APM) was used to monitor corrosion of aluminum in an aqueous sodium hydroxide environment. 7 refs., 10 figs.
