氟碳封孔剂封孔处理对8YSZ热障涂层电化学腐蚀及抗盐雾腐蚀性能的影响
Effect of Sealing Treatment with Fluorocarbon Sealant on Electrochemical Corrosion Behavior and Salt Spray Corrosion Resistance of 8YSZ Thermal Barrier Coating
摘 要
采用氟碳罩光漆作为封孔剂,对大气等离子喷涂质量分数8%氧化钇稳定氧化锆(8YSZ)热障涂层进行封孔处理,研究了封孔处理对涂层微观结构、电化学腐蚀性能及抗盐雾腐蚀性能的影响。结果表明:氟碳罩光漆因毛细现象而渗透进涂层,封孔后涂层表面粗糙度由未封孔的5.4 μm降低至0.8 μm,润湿角由未封孔的61.99°增大至70.58°;封孔后涂层的自腐蚀电位由未封孔的-0.308 V降低至-0.42 V,说明封孔剂相对于涂层为阳极性;封孔后涂层出现钝化现象,极化电阻增大,自腐蚀电流密度降低至1.26×10-6 A·cm-2,说明涂层腐蚀阻力提高;氟碳罩光漆在中性盐雾环境下对热障涂层有良好的封闭作用,能有效抑制Cl-向涂层内部扩散。

Abstract
The atmosphere plasma sprayed 8wt% Y2O3 stabilized ZrO2 (8YSZ) thermal barrier coating was sealed with the sealant of fluorocarbon finish paint. The effects of sealing treatment on the microstructure, electrochemical corrosion behavior and salt spray corrosion resistance of the coating were investigated. The results show that the fluorocarbon finish paint permeated into the coating due to capillarity action. The surface roughness of the coating was reduced from 5.4 μm before sealing to 0.8 μm after sealing, and the contact angle increased from 61.99° before sealing to 70.58° after sealing. The self-corrosion potential of the coating decreased from -0.308 V before sealing to -0.42 V after sealing, indicating the sealing agent was anodic relative to the coating. After sealing, the passivation phenomenon of the coating was observed, the polarization resistance increased, and the self-corrosion current density decreased to 1.26×10-6 A·cm-2, indicating that the corrosion resistance of the coating increased. The fluorocarbon finish paint could provide a good sealing effect on the thermal barrier coating in the neutral salt spray environment, which could effectively inhibit the diffusion of Cl- into the coating.
