Abstract

Microdefects in the rust layer of conventional steel and weathering steel were investigated by synchrotron X-ray micro tomography to understand the effect of defects on corrosion resistance. The rust layer of the weathering steel contained fewer and smaller defects than that of the conventional steel. A good correlation existed between the volume of defects and ion permeation of the rust layer obtained by EIS. In comparison with the conventional steel, the tomography results indicated that a protective layer formed on the weathering steel.
