ABSTRACT

The results of predictions concerning the long-term corrosion losses of structural metals in the continental territory of Russia with rural atmospheres and in certain locations with urban atmospheres are presented. A power-linear model is used to predict long-term corrosion losses. Two variants for estimating the coefficients in the model are used. The first variant is presented in ISO 9224 international standard (ISO variant). In the second variant (the new variant), new dose–response functions (DRF^N) were used to predict the first-year corrosion losses of metals. In the new variant, the time for corrosion rate stabilisation (τ_stab) is taken to be 6 years. Moreover, the stochastic relationship between the n coefficient, which characterises the protective properties of corrosion products, with the atmosphere corrosivity is used. Based on the predictions obtained for long-term corrosion losses, mapping of the territory of Russia is given for the two variants.

摘要

介绍了在具有农村大气的俄罗斯大陆领土和具有城市大气的某些地点的结构金属长期腐蚀损失的预测结果。功率线性模型用于预测长期腐蚀损失。使用两个变量来估计模型中的系数。第一个变体出现在 ISO 9224 国际标准（ISO 变体）中。在第二个变体（新变体）中，新的剂量反应函数 (DRF ^N ) 用于预测金属的第一年腐蚀损失。在新的变体中，腐蚀速率稳定 ( τ _stab )的时间为6 年。此外，n之间的随机关系系数，表征腐蚀产物的保护性能，使用大气腐蚀性。根据对长期腐蚀损失的预测，给出了两种变体的俄罗斯领土地图。
