Abstract

Abstract The main aim of this experimental study is to test the novel type of coupon installation. This set-up was used to carry out the corrosion process under aggressive conditions. Moreover, the effect of corrosion inhibitors on the scale-forming tendency was evaluated. The corrosive conditions were defined by using the Langelier Saturation Index (this index is an approximate indicator of the degree of saturation of CaCO3 in water) and the Ryznar stability index (this index is allowed to determine if the liquid sample is aggressive or not). Additionally, the inductively coupled plasma optical emission spectroscopy analysis was used to obtain the iron and calcium ions concentrations in the liquid samples from the tested coupon installation. The corrosion process for the established conditions was also described using the corrosion rate of the tested coupons. The obtained investigation contributes significantly by developing the novel coupon installation and demonstrating the procedure for testing the corrosion process with the application of coupons. This setup and method might be successfully applied for accelerated laboratory tests.

采用新型联轴器装置进行腐蚀过程评估

摘要:本实验研究的主要目的是对新型券式安装进行测试。该装置用于在腐蚀性条件下进行腐蚀过程。此外，还评价了缓蚀剂对结垢倾向的影响。腐蚀条件通过Langelier饱和指数(该指数是CaCO3在水中饱和程度的近似指标)和Ryznar稳定性指数(该指数可以确定液体样品是否具有腐蚀性)来定义。此外，还利用电感耦合等离子体发射光谱分析方法获得了所测贴片装置液体样品中的铁离子和钙离子浓度。用试验试样的腐蚀速率描述了在既定条件下的腐蚀过程。所获得的研究成果通过开发新的粘结剂装置和演示应用粘结剂测试腐蚀过程的程序作出了重大贡献。该装置和方法可成功应用于实验室加速试验。
