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 paint substantially containing copper pigment was lower than that of silver color paint containing Al pigment was observed.

6061-T6铝合金在海水中金银装饰涂层腐蚀行为的研究

本研究检测了高强度6061 T6铝合金的金属涂层、未涂层和受损涂层在海水中的耐腐蚀性。制备了含有两种不同金属颜料的溶剂型涂料，并用该涂料制备了Al6061T6合金涂层。采用电化学阻抗谱法测定腐蚀过程。根据电势和电流变化值计算Ecor和Rp值。结果，从Ecor、Rp、SEM-EDX图像和奈奎斯特曲线确定，冲击涂层的耐腐蚀性较低。观察到基本上含有铜颜料的金色涂料的耐腐蚀性低于含有Al颜料的银色涂料。
