二氧化碳腐蚀影响因素的层次分析法

THE ANALYTIC HIERARCHY PROCESS OF INFLUENCING FACTORS IN CARBON DIOXIDE CORROSION

二氧化碳腐蚀的影响因素众多,这些因素对二氧化碳腐蚀影响的相对重要程度(权重)是进行腐蚀预测和防护决策的关键,但是现有的文献资料往往没有以定量的方式明确界定各影响因素的权重,影响了腐蚀预测和防护决策的准确性。为此,本工作采用层次分析法,结合相关文献给出了影响因素的权重集,以定量的形式确定了CO2腐蚀影响因素的相对重要度。

The relative importance （i. e, weight） of the factors affecting CO2 corrosion of steels is a key for corrosion prediction and protection. However, the open literature generally can not explicitly define the relative importance of every influencing factor in definite quantity, which will affect the correctness of corrosion prediction and protection. Using analytic hierarchy process（AHP）, the weights of various influencing factors were calculated, which quantitatively showed the relative importance of different factors.
