摘要/Abstract

摘要： 基于广东省输电线路分布情况，在城市、工业、海洋和乡村 4 种环境中选取有代表性的 10 条杆塔线路，通过 1 年的现场暴露实验研究了杆塔用 Q235 钢的大气腐蚀行为，在 6、12 个月时各取样一次; 利用失重法测量各挂片的单位面积腐蚀失重，研究了不同环境中的腐蚀失重规律，并采用 X 射线衍射仪( XＲD) 和扫描电子显微镜( SEM) 对腐蚀产物结构和微观形貌进行表征．结果表明: 广东省大气腐蚀等级主要为 C3，其次为 C2，属于中度腐蚀; 不同特征的环境对大气腐蚀的影响从重到轻依次为重工业、海洋 + 轻工业复合、海洋和特大城市、中小型城市及乡村; 在 12 个月的试验周期内，Q235 钢前 6 个月的腐蚀速率明显高于后 6 个月; 腐蚀产物主要为花瓣网状和细针状结构的 α-FeOOH 和 γFeOOH，在海洋环境中还出现少量 β-FeOOH

Abstract: : The atmospheric corrosion behavior of Q235 steel used as the transmission tower material was investigated systematically in the 10 representative transmission lines of four typical atmospheric environments ( urban，industrial，marine and rural) by field exposure in Guangdong Province for one year． The period for recapturing samples from the field station lasted 6 and 12 months respectively． Their corrosion weight losses in unit area were measured to investigate the corrosion rule of Q235 steel． X-ray diffraction ( XＲD) and scanning electron microscopy ( SEM) were applied to analyze the microstructure and morphology of the corrosion products respectively．Ｒesults suggested that the atmospheric corrosion grade of a large part of Guangdong Province belongs to C3 and other parts belong to C2，a moderate rank as a whole． The influence of different environments on the atmospheric corrosion is different as follows: the heavy industrial environment，the compound one of marine and light industry，the marine and urban one，the little city and rural one． The corrosion rate of Q235 in the previous 6 months is obviously higher than that in the latter stage from 6 to 12 months in one-year-field exposure． The corrosion products are mainly αFeOOH and γ-FeOOH with net-or needle-like micro morphology，and a small amount of β-FeOOH is observed in the marine environment

Key words: transmission tower, Q235 steel, atmospheric corrosion behavior, corrosion weight loss, corroion grade
