双相不锈钢的冲蚀行为及其影响因素研究进展
Research Progress on the Erosion-corrosion Behavior and its Influence Factors of Duplex Stainless Steels
摘要
Abstract
Erosion-corrosion,characterized by the damage of materials due to high-speed relative motion in corrosive fluids,poses significant challenges in industries such as petrochemical,maritime,and pipeline transportation.Duplex stainless steel(DSS)is an ideal material for studying erosion-corrosion behavior due to its superior corrosion resistance and mechanical properties.This review summarizes the current research on DSS under erosion conditions,focusing on the impact of micro-structure,chemical composition,heat treatment processes,and fluid environment on its erosion-corrosion behavior.The find-ings indicate that the erosion-corrosion resistance of DSS is closely related to the formation of its passive film,phase bal-ance,precipitate formation,mechanical properties,as well as factors such as flow rate,impact angle,particulate matter,tem-perature,and pH.By optimizing alloy composition and employing heat treatment processes such as solution treatment,aging treatment,and surface modification,the erosion-corrosion resistance of DSS can be effectively enhanced.The review con-cludes with an outlook on future research directions,including a deeper understanding of the interaction mechanisms be-tween corrosion and erosive wear,elucidating the erosion-corrosion mechanisms at"critical flow rates,"exploring the role of passive films,and investigating the erosion-corrosion resistance of DSS weld overlays and welded joints.关键词
