Abstract

ABSTRACT Deicing agents in winter maintenance are critical in providing safe roads at all times. Sodium chloride (SC) is the most common, efficient and favourable agent but has a drawback of high corrosiveness, thus substantially shortening the service life of metal-based transport infrastructures. This work focuses on corrosion and addresses approaches for the following corrosion test methods that quantify the mass loss of metals for different deicing agents: standardised neutral salt spray test (ISO 9227), salt solution immersion test (ASTM G31-72) and alternate immersion test (ISO 11130). A wide range of different deicing agents with and without corrosion inhibitors are tested on unalloyed steel, and an analytical and visual comparison is made. Results reveal a substantially reduced corrosion effect at reasonable costs by selecting the appropriate deicing agent with or without corrosion inhibitors. For the final selection of deicers, deicing performance and cost-effectiveness are compared.

金属腐蚀方法分析及低成本低腐蚀除冰剂的鉴定

除冰剂在冬季维护中对于始终保证道路安全至关重要。氯化钠(SC)是最常见、最有效和最有利的腐蚀剂，但具有高腐蚀性的缺点，从而大大缩短了金属基运输基础设施的使用寿命。这项工作的重点是腐蚀，并解决了以下腐蚀试验方法的方法，这些方法量化了不同除冰剂的金属质量损失:标准化中性盐雾试验(ISO 9227)，盐溶液浸泡试验(ASTM G31-72)和替代浸泡试验(ISO 11130)。在非合金钢上试验了各种不同的除冰剂(含和不含缓蚀剂)，并进行了分析和直观的比较。结果表明，通过选择合适的除冰剂(含或不含缓蚀剂)，可以在合理的成本下大幅降低腐蚀效果。最后对除冰剂的选择进行了除冰性能和成本效益的比较。

期刊介绍： Corrosion Engineering, Science and Technology provides broad international coverage of research and practice in corrosion processes and corrosion control. Peer-reviewed contributions address all aspects of corrosion engineering and corrosion science; there is strong emphasis on effective design and materials selection to combat corrosion and the journal carries failure case studies to further knowledge in these areas.
