Abstract Rust analyses were made on coupons of 08CuPVRE and two other steels as control after two-year outdoor exposure in Chengdu using scanning electron micrography, electron probe and X-ray diffraction techniques. Results showed that the main composition of the inner rust layer of 08CuPVRE is Fe3O4.The layer is dense, continuous and of incomplete crystalization. An enrichment of Cu, P elements in the niner rust layer was observed.Incombination with corrosion weight loss data the effect of elemental enrichment on the structure of inner rust layer and the self-mending characteristics of fissures in the layer was discussed.
