采用等离子体电解氧化(PEO)和Ce盐封法制备复合涂层,水热处理沉积层状双氢氧化物(LDHs),然后用植酸(PA)离子交换反应修饰复合涂层。采用XRD、XPS、FT-IR、SEM、EDS和GDOES对涂层进行了表征,最终涂层由LDHs/Mg(OH)2/CeO2/Ce(OH)3组成,且Ce分布不均匀。采用极化曲线、EIS、浸没试验和SVET等方法研究了材料的防腐和自愈能力。由于Ce与磷酸盐的协同作用,PA改性后的复合涂层表现出最优异的防腐和自修复能力。
A composite coating was produced via (i) plasma electrolytic oxidation (PEO) with Ce salt sealing, on which layered double hydroxides (LDHs) were depositedviaa hydrothermal treatment, and (ii) then modified by phytic acid (PA)viaan ion-exchange reaction. The final coating (characterized using XRD, XPS, FT-IR, SEM, EDS and GDOES) consisted of LDHs/Mg(OH)2/CeO2/Ce(OH)3with a non-uniform Ce distribution. The corrosion protection and self-healing ability were investigated using polarization curves, EIS, immersion tests and SVET. The composite coating modified with PA showed the most superior corrosion protection and self-healing ability, attributed to the synergistic effect between Ce species and phosphate.
