Abstract:
The (E)QCM is a versatile method to estimate real-time mass changes in situ.These mass changes reflect different reactions, such as adsorption, dissolution, or film growth. Toobtain more complete information on the processes occurring on the surface, the (E)QCM can becombined with different analytical techniques, for example, surface spectroscopy, IR absorption, orelectrochemical impedance spectroscopy. Its high sensitivity permits the study of mass changescorresponding to fractions of a monolayer. However, a quartz sensor is also sensitive to thecoupling between its surface and the surrounding environment. For a correct data interpretation, itis important that the effects of viscous loading, double layer structure, surface roughness, andtemperature are taken into consideration. In the field of corrosion, the EQCM has been successfullyapplied to a wide variety of problems. One example is the study of uniform dissolution inidentifying partial currents by comparing the mass loss with the total current. It has also beenused to calculate adsorption isotherms for organic inhibitors. Another application is the study ofpassive films on stainless steels, where it has been shown that a combination with XPS gives thepossibility to study film growth kinetics for alloys with several alloy elements showing widelydifferent chemical behavior.
