Research Status and Prospect of Stabilization Treatment Technique for Rust Layer on Weathering Steel Surface

Abstract

Weathering steel is used more and more widely in various fields of production and life.A rust layer stabilization treatment on the surface of weathering steel before usage can enhance both material life extension and beautification，promoting the mutual coordination between weathering steel and its service environment.In this paper，the research status of surface stabilization treatment technique of rust layer on weathering steel was summarized，which mainly included the formation，composition，structure and protection mechanism of rust layer，especially the disadvantages of traditional technology and novel technology.Finally，the further development of the surface rust layer stabilization treatment was prospected.
