摘要

目前对大气腐蚀的评估是基于对大气盆地(AB)的研究。用于大气腐蚀估算的模型需要测量多个气象和大气污染参数，这使得估算变得复杂。在热带大气腐蚀中要考虑的主要气象参数与温度(T)和相对湿度(RH)有关。这些参数也包括在加湿时间(TDH)的计算中。此外，与腐蚀有关的大气污染物是氯化物(Cl)和二氧化硫(SO2)。哥斯达黎加的西部中央山谷(WCV)是一个低污染的AB;因此，采用基于少量大气参数的简化大气腐蚀模型是可能的。分析了研究区域的气象参数对海拔的依赖性及其在WCV腐蚀速率(Vcorr)简化经验方程中的适用性。将这些简单关系与ISO 9223-2012标准提出的模型进行了比较。

Prediction of atmospheric corrosion from meteorological parameters: Case of the atmospheric basin of the Costa Rican Western Central Valley

The assessment of atmospheric corrosion is currently based on studies of atmospheric basins (AB). The models applied to the estimation of atmospheric corrosion imply measurements of several meteorological and atmospheric pollution parameters, which make the estimation complex. The main meteorological parameters to be considered in tropical atmospheric corrosion are associated with temperature (T) and relative humidity (RH). These parameters are also included in the calculation of the time of humidification (TDH). In addition, the atmospheric pollutants associated with corrosion are chloride (Cl) and sulphur dioxide (SO2). The Western Central Valley (WCV) in Costa Rica is a low-pollution AB; therefore, it is possible to employ simplified atmospheric corrosion models based on few atmospheric parameters. The meteorological parameters of the study region were analyzed in terms of their dependence on altitude and their applicability in simplified empirical equations of the corrosion rate (Vcorr) for the WCV. These simple relations were compared with the model proposed by the ISO 9223-2012 standard.
