Outline of Final Research Achievements

We have proposed new methods for force measurement, in which the sliding gap is precisely adjusted, and observation of gap shapes during sliding, in order to clarify lubrication phenomena at small sliding gaps. We have succeeded in confirming the principle of the proposed methods and clarified that the methods enable us to quantify gap-dependences of lubricant properties, boundary characteristics, and lubrication performance. The methods developed in this study can be expected to be effective methods for clarifying the lubrication phenomenon at nanometer-gaps.
