Abstract The purpose of this study is to investigate the fractal dimension of the surface morphology of the steel structure corroded by neutral salt-spray. The artificial accelerated corrosion tests of 7 batches of hot-rolling H beams were carried out, and the 3D topography data were obtained by surface morphology measuring using 3D non-contact surface topography scanner. The fractal dimension of corroded surface morphology was calculated according to box width variation method and its variation with corrosion age, mass lose rate and surface roughness were analysed. Test results show that surface morphology of neutral salt-spray accelerated corrosion steel structure can be characterized by fractal dimension. With the corrosion age increasing from 0 month to 6 months, the fractal dimension of the section curves and surfaces increased with a gradual and slow growth trend, and the fractal dimension periodically fluctuated after the corrosion age exceeds 6 months. The fractal dimension of two directions of corroded steel plate takes on the anisotropic property, and the fractal dimension of the rolling direction is slightly larger than that of plate width direction; the correlations between surface fractal dimension and corrosion age, weight lose rate and average height of surface roughness, which obtained according to the experiment data fitting, can be used as surface morphology characterization of the corroded steel structure.

Key words： neutral salt-spray corrosion steel structure surface morphology fractal dimension
