Nanotribological characterization of industrial polytetrafluorethylene-based coatings by atomic force microscopy / A. Podestà, G. Fantoni, P. Milani, C. Guida, S. Volponi. - In: THIN SOLID FILMS. - ISSN 0040-6090. - 419:1(2002), pp. 154-159. [10.1016/S0040-6090(02)00778-2]
Abstract:
We present the result of a systematic study of the tribological properties of industrial polytetrafluorethylene (PTFE)-based coatings carried out with an atomic force microscope. A new characterization protocol allowed the reliable and quantitative assessment of the friction coefficient and adhesion forces at the sub-micrometer scale even for highly corrugated industrial samples. We have studied and compared PTFE coatings charged with different additives in dry and humid environment. The influence of additives and humidity on the friction coefficient and on adhesion forces has been investigated using standard silicon nitride tips as sliders in the low-load regime.
