Using the Langmuir-Blodgett method, mon-omolecular layers were easily deposited on a flat surface. The thickness of these layers (LB films) can be controlled with very high accuracy. The frictional coefficient and elec-trical contact resistance were measured be-tween a steel ball and a flat copper surface covered with several layers of stearic acid-LB films. The ratio of metallic contact was calculated from the electrical contact resist-ance. The obtained results indicated that the stearic acid-LB films act as an efficient lubri-cant, having a high contact resistance and a low frictional coefficient.
