In situ simultaneous measurement with ir-ras and qcm for investigation of corrosion of copper in a gaseous environment

Abstract To elucidate the initial corrosion behavior at metal surfaces in corrosive gas environments a method for in situ simultaneous measurements using IR-RAS and QCM was developed. The technique was applied to copper in air containing 10 ppm SO 2 and 80% relative humidity and the results were discussed.
