An oiliness agent, for example stearic acid, makes reduction of friction coefficient by forming chemisorption layers. Predominant factors over this reduction effect are experimentally investigated in reciprocating friction with small amplitude. In this experimental condition, severe starvation of lubricant in a contact area proceeds with increasing into the friction pass. According as this starvation, defect of the chemisorption layers increases and thus the friction coefficient abruptly increases. Endurance time of chemisorption layer up to abrupt friction increase positively depends on both friction velocity and resting time of upper specimen. These results show that time to re-flow into the contact area and re-from the layer may predominantly influence the endurance of the layer.
