- Abstract
This study examined the corrosion resistance of the metallic paint coated, uncoated and damaged paint coated form of the high-strength 6061-T6 Al alloy inside seawater. Solvent-based paint containing two different metallic pigments produced with an alkyd binder was produced and the coating of Al 6061-T6 alloy was made with this paint. To determine the course of corrosion electrochemical impedance spectroscopy method was used. Ecor and Rp values were calculated from potential and current change values. As a result, it was determined from the Ecor, Rp, SEM -EDX images, and Nyquist curves that the corrosion resistance of impact coatings was lower. The corrosion resistance of gold color (Ecor -0.66320 V, Rp 60030.22 ohm)paint substantially containing copper pigment was lower than the corrosion resistance of silver color paint substantially containing Al pigment (Ecor -0.72912 V, Rp 22264.05 ohm) was observed.
