Abstract

A ductile erosion model embodying the mechanisms of erosion involving cutting wear and repeated plastic deformation has been developed to predict erosion rates of boiler grade steels. The issue of erosion-oxidation interaction has also been addressed to further predict the mass loss resulted from this composite mechanism. A deterministic formalism for the kinetics of oxide-scale growth and a probabilistic approach to characterize the material loss are employed to describe simultaneous actions of high-temperature oxidation and mechanical erosion. The model predictions are in good agreement with the published data.

锅炉级钢的侵蚀氧化响应:数学研究

建立了包含切削磨损和反复塑性变形的韧性侵蚀模型，用于预测锅炉级钢的侵蚀速率。本文还讨论了侵蚀-氧化相互作用的问题，以进一步预测这种复合机制造成的质量损失。采用确定性的氧化垢生长动力学形式和表征材料损失的概率方法来描述高温氧化和机械侵蚀的同时作用。模型预测结果与已发表的数据吻合良好。
