Abstract
The atmosphere in many cities along the coastal lines such as Qingdao in China has been polluted with SO2 due to the development of industry, and the atmosphere therefore has been changed to coastal-industrial atmosphere. The corrosion behavior and mechanism of steels in coastal-industrial atmosphere with the co-existence of SO2 and Cl are different from that in the coastal atmosphere containing only Cl or the industrial atmosphere containing only SO2. In addition, pH value is diverse in different coastal-industrial atmosphere. However, there are only few researches on the effect of pH value on the corrosion evolution of steels in the coastalindustrial atmosphere. Almost all the atmospheric corrosion data of steels were obtained by the field exposure test, which could not reflect the dependence of the atmospheric corrosion evolution of steels on pH value due to the difficulties in *国家自然科学基金项目 51201170和51131007,国家重点基础研究发展计划项目2014CB643300和国家材料环境腐蚀平台项目资助 收到初稿日期: 2014-07-23,收到修改稿日期: 2014-11-14 作者简介:陈文娟,女, 1986年生,博士生 DOI: 10.11900/0412.1961.2014.00407 第191-200页 pp.191-200
