摘要: Abstract X-ray photoelectron spectroscopy has been employed to estimate the iso-electric point (IEPS) of inorganic surfaces importance in adhesion. The method makes use cation and anion exchange a series aqueous solutions covering range pH values. From knowledge solution equilibria involved it is possible IEPS. This particular advantage that applicable planar surfaces, and, adhesion studies, terminal oxide layers on metals contain concentration gradients such as those have treated with conversion coating.
