Abstract
We study the effects of surface roughness and composition of Ni x Fe 1 − x material on a talc particle-surface adhesion. Experimental results are astonishingly consistent with our theoretical simulation that the lowest value of the total interaction potential between talcum and the material is proportional to the probability of contamination. The AFM result s’ tendency corresponds to surface force s’ simulation. Finally, we discover the electromagnetic description of the interaction between talcum and the rough surface at the lowest potential is proportional to the sum of each side’s square that involves dielectric constants and surface’s roughness. • The interaction potential is expressed as a dielectric property and a dimensional size in a simplified form. • The connection between the depth value of the surface interaction potential and the contamination probability is shown. • The comparison of the interaction force between theoretical and experimental results is verified via using the AFM technique.
