Comparison of Potentiodynamic Polarization and Weight Loss Measurement Techniques in the Study of Corrosion Behavior of 6061 Al/SiC Composite in 3.5 M NaCl Solution
6061 Al/SiC composite is one of the widely used composite for structural applications in marine industry. Corrosion is the major concern in marine applications. The corrosion behavior of the aforesaid composite is determined using two techniques namely potentiodynamic polarization and weight loss measurements. It is observed the results obtained by both techniques showed similar trend. The peak aged composite show lower corrosion resistance in 3.5 M NaCl solution at room temperature compare to other groups of aged composite. The aluminum as corrosion resistive coating reduces the corrosion rate of the peak aged composite to a considerable extent.
