Abstract

Abstract The degradation of materials due to erosion–corrosion occurs on the components that handle particle-laden corrosive slurry. The combined attack of mechanical erosion and corrosion shows increased material loss than the individual action of erosion and corrosion. The synergy accelerates material removal by eroding the corroded surface layer and corroding the surface due to the elimination of the passivating oxide layer by erosion. The synergism of erosion–corrosion is found to be more complex. Further, the coupled effect of mechanical erosion and electrochemical corrosion and the factors influencing erosion–corrosion still needs to be fully investigated. This review aims to provide a general and detailed summary of the interaction between erosion and corrosion of materials for the applications of pump impellers, pipelines for desalination, and oil and gas transportation. Importance is also given to the factors influencing erosion–corrosion, such as erodent particle properties (hardness, size, and shape), slurry properties (particle concentration, pH value, temperature), and flow characteristics (impingement angle, velocity). The various erosion models and the most used apparatus have also been reviewed.
铁质管道材料冲蚀-腐蚀的协同效应和个体效应综述
处理含颗粒的腐蚀性泥浆的部件由于侵蚀腐蚀而发生材料的降解。机械侵蚀和腐蚀的共同作用比侵蚀和腐蚀的单独作用表现出更大的物质损失。协同作用通过侵蚀被腐蚀的表面层和由于侵蚀消除钝化氧化层而腐蚀表面来加速材料的去除。发现侵蚀-腐蚀的协同作用更为复杂。此外,机械侵蚀和电化学腐蚀的耦合效应以及影响侵蚀腐蚀的因素还有待进一步研究。本文就材料在泵叶轮、海水淡化管道、油气输送等领域的腐蚀与侵蚀相互作用进行了综述。对侵蚀腐蚀的影响因素也给予了重视,如侵蚀颗粒特性(硬度、尺寸和形状)、浆料特性(颗粒浓度、pH值、温度)和流动特性(撞击角、速度)。对各种侵蚀模型和最常用的仪器进行了综述。

期刊介绍: Corrosion Reviews is an international bimonthly journal devoted to critical reviews and, to a lesser extent, outstanding original articles that are key to advancing the understanding and application of corrosion science and engineering in the service of society. Papers may be of a theoretical, experimental or practical nature, provided that they make a significant contribution to knowledge in the field.
