摘要

玻璃陶瓷类搪瓷涂层可以应用于各种配置的低合金和碳钢部件，包括管，通过不同的成本效益技术方法，厚度可达300微米。对搪瓷涂层在酸性环境、沸水和含CO2-H2S气体的高温高压(HT-HP)蒸汽中的耐蚀性进行了测试和评估，模拟了炼油厂、油气和地热生产中的一些过程。具体来说，首次对珐琅涂层进行了模拟高温高压井下生产条件的测试。对制备的釉质玻璃涂层进行了显微组织检查和分析，发现其成分和结构降解程度不明显。在考虑的环境中，通过搪瓷对钢材进行高水平的保护，证明了这些涂层在不同与腐蚀相关的工业过程中的潜力。

Enamel (glassy) coatings for steel protection against high temperature corrosion

ABSTRACT Vitreous ceramic-like enamel coatings can be applied onto low-alloy and carbon steel components of various configurations, including tubulars, by different cost-effective technological methods achieving thicknesses up to 300 µm. Corrosion resistance of the enamel coatings in acidic environments, boiling brines and high temperature – high pressure (HT-HP) steam with a presence of CO2-H2S containing gases simulating some processes in refinery, oil & gas and geothermal production was tested and evaluated. Specifically, the testing in simulating HT-HP downhole production conditions was conducted for the enamel coatings for the first time. Microstructural examination and analysis of the obtained enamel glassy coatings revealed their insignificant compositional and structural degradation. A high level of steel protection by enamelling in considered environments demonstrated these coatings’ potential for different corrosion-related industrial processes.
