摘要
通过综合运用EDS、FTIR和电化学测试等多种分析技术,揭示了室内制备的涂层独特的化学组成和结构特征,以及其在不同腐蚀环境下的防护性能.结果表明:新型涂层的化学性能表现在其独特的成分配比中,尤其是 Zn和 Cr的富集,这些元素为涂层提供了显著的化学稳定性和优异的防腐蚀性能.EDS分析验证了涂层中元素的均匀分布,FTIR分析揭示了Si—O—Si和Zn—O化学键的存在,这些结构特征对于增强涂层的耐腐蚀能力至关重要.电化学测试结果进一步证明了新型涂层在碱性环境下具有极低的平均腐蚀速率(0.05 mm·a-1),显著优于传统涂层,体现了其卓越的耐腐蚀性能.此外,成本效益分析结果表明,新型涂层长期应用能够显著降低维护成本,为每平方米节省高达20元,显示出其优越的经济性.
Abstract
Through the comprehensive use of various analytical technologies such as EDS,FTIR and electrochemical testing,the unique chemical composition and structural characteristics of the indoor-prepared coating were comprehensively revealed,as well as its protective performance in different corrosive environments.Experimental results showed that the chemical properties of the new coating were reflected in its unique component ratio,especially the enrichment of Zn and Cr.These elements provided the coating significant chemical stability and excellent anti-corrosion properties.EDS analysis verified the uniform distribution of elements in the coating,and FTIR analysis revealed the existence of Si—O—Si and Zn—O chemical bonds.These structural features were crucial for enhancing the corrosion resistance of the coating.The electrochemical test results further proved that the new coating had extremely low average corrosion rate(0.05 mm·a-1)in an alkaline environment,which was significantly better than traditional coatings,reflecting its excellent corrosion resistance.In addition,through cost-benefit analysis,this study showed that long-term application of the new coating could significantly reduce maintenance costs,saving up to 20 yuan per square meter,demonstrating its superior economics.
