摘要
分别用35%NaCl和去离子水来模拟苛刻与和缓的大气腐蚀环境,研究了交替腐蚀环境下耐候钢的腐蚀行为。结果表明,耐候钢在苛刻与和缓交替进行的腐蚀环境下比在单一环境下更容易形成致密锈层;腐蚀环境先苛刻后和缓比先和缓后苛刻更有利于形成保护性锈层。
The corrosion behavior of weathering steel in alternate corrosion environment was investigated with 35%NACl and deionized water as harsh and gentle atmospheric corrosion environnient, respectively. The results show that a dense rust layer is formed easily for the steel corroded in the alternate corrosion environment comparing with the single corrosion environment. And it is easier to form the rust layer for the steel corroded in the environment of rigour first and then ease comparing with that of ease first and then rigour.
