- Recent Progress in Microtribology. Atomic-scale Tribology Studied by Frictional Force Microscope.
抄録
A two-dimensional frictional force microscope study has been made on an atomic scale tribology between a sharp tip of a single asperity of Si3N4 and an atomically flat surface of NaF(100), where the frictional force becomes two-dimensional vector. By increasing the normal load from 1.4 nN to 2.2 nN, the periodicity of the two-dimensional stick-slip motion of the tip is remarkably changed from lattice periodicity to atomistic periodicity. This load dependence of the periodicity qualitatively agrees with that of the tip-surface interaction due to surface relaxation by increasing the load, which is theoretically predicted using computer simulation. Within the load range where the atomistic periodicity appears, the load dependence of the amplitude of the friction shows anomalous behavior. Further, by increasing the load more than ∼3.6 nN it is suggested that the tip and/or NaF surface break down, because the two-dimensional stick-slip motion disappears.
