Abstract Applications of fractal theory in describing corrosion behaviors and creating co rrosion model were introduced based on the recent progresses in the field.Severa l successful samples were demonstrated in details,namely：(1) to correct the ind ex denoting corrosion fluctuation(e.g.,standard deviation)by fractal dimension ( FD) to better describing corrosion behaviors；(2) to observe fractal characteris tics on corroded steel surface (e.g.，distribution for micro-droplet formation i n early atmosphere and for pit diameter and depth in soil corrosion) and obtain distribution FD；(3) to propose a new approach to estimate 2-dimension FD(D2 D) and 3-dimension FD(D3D) of corrosion image and find that they respect ively denoted FD for pit diameter and depth distribution；(4) to create corrosio n formation model based on fractal dynamic process to predict corrosion developi ng of metals in soil and atmosphere，and display the parameter-relation between fractal model and experimental model.
