摘要
大气腐蚀图是一种在地理地图上描述目标区域大气环境腐蚀性强弱的图示方法,可为工程的防腐设计、运行维护和寿命预测等提供数据支持,对于节支防腐成本和保障工程安全意义重大。大气腐蚀图由最初的栅格、等值线图发展到了更为直观、更方便读取的色斑图。剂量响应函数的发展解决了从暴露试验中难以获取足够腐蚀数据的问题,绘图者可通过环境数据快速地计算出目标区域的大气腐蚀数据。在大气腐蚀图绘图中主要使用反距离加权和克里金插值模型实现数据空白区域的赋值,但是相关模型的适用性和误差分析未见研究报道。基于大气腐蚀图绘制技术的发展现状,建立能够反映材料腐蚀机理、适用性更强且误差更小的剂量响应函数和研究更适用于大气腐蚀数据的空间插值模型是大气腐蚀图绘制技术的发展方向。
Atmospheric corrosion map is a graphical method for describing the corrosivity of the atmospheric environment of a designated area on a geographic map,which can provide data support for the anti-corrosion design,maintenance,and life prediction of the outdoor projects.It is of great significance to save anti-corrosion cost and ensure the safety of the project.Atmospheric corrosion maps have evolved from the initial grid and contour maps to more intuitive and easy-to-read colorful maps.The development of the dose response function solves the problem that it is difficult to obtain sufficient corrosion data from the exposure test,and the atmospheric corrosion data of the target area can be calculated quickly by using the environmental data.The inverse distance weighting and kriging interpolation models are mainly used in constructing atmospheric corrosion maps to predict the assignment of data blank areas,but the relevant applicability and error analysis of the models have not been reported yet.Based on the development of atmospheric corrosion mapping technologys,the development directions of atmospheric corrosion mapping technology may be proposed as follows:the establish Dose Response Functions that reflect the corrosion mechanism of materials,with greater applicability and less error,and to study spatial interpolation models that are more suitable for atmospheric corrosion data.
