如果没有防腐涂料的保护，车辆、桥梁和工业遗产将无法长久保存。当这些涂层失效或损坏时，黑色金属需要进一步保护。为了深入了解涂层失效，在苏格兰各地对历史悠久的锻铁和低碳钢上发现的油漆层和腐蚀产物进行了调查。人们还发现，腐蚀是导致历史悠久的装甲车结构损坏的主要原因。
在保护范围内选择涂层时，决策是基于定性数据和从业者的经验，而不是基于特定环境条件下特定铁合金的证据标准。有限的定量数据存在，因此本研究旨在通过标准化的方法产生量化的数据。为了提供基于实验室的测试的环境背景，考虑了坦克博物馆的温度和湿度数据。因此，在受控的温度和相对湿度下，通过使用灵敏的腐蚀监测技术，对历史装甲钢上的透明涂层的防腐蚀性能进行了评估。
为了与保护部门的相关性，考虑了通用材料、方法和环境条件，并将其标准化。对钢材进行氧化铝喷砂处理，去除了污染物，并为Paraloid B72和Cosmoloid H80提供了一个键控表面，这是一种受保护的透明涂层，也是一种现代硅烷基涂层Siliglide 10。所有三种涂层都为钢提供了保护，无论是应用于清洁的表面还是预腐蚀的表面。最好的治疗方法，因此治疗建议保护区域的油漆损失是清洁表面，并应用三层Paraloid B72。
所使用的标准化方法允许其他研究人员为数据库的生产和保护范围内的未来标准提供可比数据。
Without the protection provided by anti-corrosive paints, vehicles, bridges and industrial heritage would not have survived for long. Where these coatings fail or are damaged, ferrous metal requires further protection. To provide insight into coating failure a survey of paint layers and corrosion products found on historic wrought iron and mild steel was carried out around Scotland. Corrosion has also been found to be a major contributor to structural damage of historic armoured vehicles.
When choosing coatings within conservation, decisions are based on qualitative data and practitioners’ experience rather than evidence based standards for specific ferrous alloys in particular environmental conditions. Limited quantitative data exists hence this research seeks to produce quantified data via a standardised approach. To provide environmental context for the laboratory based tests, temperature and humidity data from the Tank Museum has been considered. Thus the anti-corrosive performances of clear coatings on historic armoured steel have been assessed in controlled temperature and relative humidity by using a sensitive corrosion monitoring technique.
For relevance to the conservation sector common materials, methodology and environmental conditions were considered and standardised. Aluminium oxide blasting of the steel removed contaminants and provided a keyed surface for Paraloid B72 and Cosmoloid H80, popular clear coatings within conservation and Siliglide 10, a modern silane based coating. All three coatings offered protection for the steel whether applied to cleaned surfaces or to pre-corroded surfaces. The best treatment method and thus the treatment recommended for protecting areas of paint-loss is to clean the surface and apply three layers of Paraloid B72.
The standardised approach used allows other researchers to contribute comparable data to the production of a database and future standards within conservation.
