Abstract

The wear properties of mono- and multi-molecular layers of barium stearate are studied under various conditions of loads and speeds. The wear properties of molecular layers are compared by measuring the increase of friction coefficient and the critical number of runs with the abrupt rise of friction coefficient during repetition of sliding over the same track. As the result of experiment, it is found that the critical number of runs is increased with the increase of film thickness or speed and the decrease of load, but there is a marked decrease in the durability of the film where the number of layers is more than about 10 molecular layers.
