摘要

摘要本研究考察了不同环境条件下耐候钢腐蚀表面的空间特征，以评估两种加速腐蚀试验的适用性。对两种类型的耐候钢进行了28天、84天和168天的两次加速腐蚀试验。同样的材料也在两个不同的位置暴露180天和365天的大气暴露测试。采用空间统计分析方法研究了耐候钢的腐蚀行为。分析表明，在两次加速腐蚀试验的早期阶段，耐候钢的腐蚀空间特性与大气暴露试验接近。此外，在ISO 16539方法B加速腐蚀试验下试验的腐蚀表面表明，与循环腐蚀试验方法a得出的腐蚀表面相比，在实际腐蚀环境中，与耐候钢的腐蚀表面更相似。

An analysis on spatial properties of corroded surface of weathering steel by different environmental conditions

ABSTRACT This study examined the spatial characteristics of the corroded surface of weathering steel by different environmental conditions to evaluate the applicability of two accelerated corrosion tests. Two types of weathering steel were subjected to the two accelerated corrosion tests for 28, 84, and 168 days. The same materials were also exposed at two separate locations for 180 and 365 days of atmospheric exposure tests. The corrosion behavior of the weathering steel was investigated by spatial statistical analysis. The analysis suggested that the spatial properties of the corrosion of weathering steel experimented in the early stage of both accelerated corrosion tests were close to those obtained in the atmospheric exposure tests. Furthermore, the corroded surfaces experimented under the ISO 16539 Method B accelerated corrosion test demonstrated a closer resemblance to the corroded surfaces of weathering steel in real corrosion environments compared to those derived from the Cyclic Corrosion Test Method A.
