摘要

研究人员开发了添加不同锌含量的有机硅涂层,以增强在不同腐蚀环境中的耐热性和耐腐蚀性。研究发现,锌会影响涂层与基材之间的附着强度,而添加 40% Zn 的涂层具有最佳的耐热性和耐腐蚀性。在高温环境中,锌的体积膨胀和熔融变形填补了涂层的缺陷,增强了涂层的物理屏蔽效果。在常温环境中,Zn 通过充当阳极和提供阴极保护,为钢基体提供化学屏蔽效果。在高温-盐雾循环环境中,Zn 的常温腐蚀产物还能填补涂层缺陷,增强高温阶段的耐热性。在高温下生成的氧化锌优先吸附常温阶段的腐蚀介质,阻碍其向基底扩散,从而同时增强了涂层的耐热性和耐腐蚀性。

Enhanced heat and corrosion resistance of organic silicone coatings by dual shielding effects of Zn powder
Organic silicone coatings added with varying Zn content were developed to enhance heat and corrosion resistance in different corrosive environments. Zn was revealed to affect the adhesion strength between the coating and the substrate, and the 40% Zn-added coating demonstrated the best heat and corrosion resistance. In high-temperature environments, the volume expansion and melting deformation of Zn filled the defects of the coating and enhanced the physical shielding effect of the coating. In ambient-temperature environments, Zn provided the chemical shielding effect to the steel substrate by acting as an anode and providing cathodic protection. In high temperature-salt spray cyclic environments, the ambient-temperature corrosion products of Zn also filled the defects of the coating and enhanced the heat resistance in the high-temperature stage. ZnO generated at high temperatures preferentially adsorbed corrosive mediums in the ambient-temperature stage, hindering their diffusion to the substrate, thereby simultaneously enhancing the heat and corrosion resistance of the coating.
