为了计算从构成附着铁锈一部分的钢中腐蚀的铁量，a，我们提出了一种考虑质量测量和使用光谱技术来估计相对铁相丰度的程序。我们推导了一个公式来计算和评估碳钢(CS)和耐候钢(WS)在室外加速腐蚀试验中的a。接触2年后，CS和WS的a值分别为0.93和0.76。铁相的相对丰度表明，这是一种非保护性和活动性的铁锈。(C)2010爱思唯尔有限公司。保留所有权利。
To calculate the amount of iron corroded from the steels that form part of the adherent rust, a, we propose a procedure that considers mass measurements and the use of spectroscopic techniques to estimate the relative iron phase abundances. We derived an equation to calculate a and evaluate it for carbon steels (CS) and weathering steels (WS) exposed to accelerated outdoor corrosion tests. The values of a are estimated at 0.93 and 0.76 for CS and WS after 2 years of exposure, respectively. The relative iron phase abundances pointed out to a non-protective and active type of rust.
