摘要：

In this study corrosion rates of aluminum, copper, brass and Stainless Steel 304 (SS 304) in tequila are reported from potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) measurements. A simple kinetic model is proposed to analyze the polarization data and to establish a comparison with EIS measurements. For the examined metals/alloys, aluminum exhibited the highest corrosion rate of ca. 6.1 pm s(-1) with a pitting corrosion tendency after being exposed to tequila (pH = 3.6). SS 304 was the most stable metal with a corrosion rate of 0.28 pm s(-1). The corrosion rate trends for all the investigated metals/alloys from potentiodynamic polarization and EIS measurements are Al > Cu > brass > SS 304.
