Bulk Acoustic Wave Technique as a Real-Time Corrosion Probe in Low-Conductivity Solution: In-Situ Corrosion Behavior of Copper in Acetic Acid

The possibility of using the bulk acoustic wave (BAW) technique to study metal corrosion in low-conductivity organic solvents was demonstrated in relation to copper corrosion in acetic acid (CH₃COOH). Effects of oxygen, cupric ions, mineral acid, and temperature were considered. The BAW sensor was found advantageous over conventional electrochemical methods in monitoring corrosion behavior in a low-conductivity system.
