Multi Fractal Characteristic of Metal Material Worn Surface with Plant Abrasive

Based on the multi-fractal theory and SEM image, the multi-fractal property of the plant abrasive to metal surface was studied. The result shows that the characteristic parameters of Delta alpha and Delta f of the multi-fractal spectrum on can reflect the morphology features of the worn surface, which are connected with volume wear, so they are regarded as characterization parameters in quantification on the surface of metallic material that is worn by plant abrasive. 15 mm.
