Abstract
Using atomic force microscopy, adhesion force and indentation mapping have been combined with measurements of topography in mapping the hardness variations on the surface of a CaCO3-filled silicone coating material. The topographic image revealed a smooth surface with protruding features, matching the size of filler particles (1-3 ím). Mapped indentation and adhesion force measurements showed that these features were associated with increased surface hardness and, also, a suppressed ability to develop adhesive interactions with the probing material (silicon nitride). Furthermore, the indentation images revealed that a boundary region of increased softness surrounded each protruding particle.
