DEVICE MODELING FRICTION PROCESS

摘要

FIELD: equipment studying mechanisms of friction. SUBSTANCE: invention is related to instruments for examination of mechanism of friction in nanotribocontacts by way of modeling process of interaction of needle of atomic-power microscope with monatomic-smooth surface of specimen under mode of measurement of lateral forces for visualization of effect of adhesion-sliding. Device modeling friction process in nanotribocontacts includes specimen simulating examined surface, probe on pendulum suspension simulating needle of atomic- power microscope and possessing adjustable center of gravity, mechanisms reading angle of inclination of probe and movement of specimen. Specimen comes in the form of plane-parallel plate with set of round holes made in nodes of two-dimensional periodic lattice where magnets of cylindrical shape imitating atoms of specimen and demonstrating vertical degree of freedom are located. Probe comes in the form disc with round holes in which same magnets are positioned. EFFECT: provision for study of mechanism of friction in nanotribocontacts. 1 dwg
