| Research Abstract |
In this study, we applied the Quartz Crystal Microbalance(QCM) method for the in-situ monitoring phenomena of lubricant additives. The QCM is a sensitive mass measuring method based on an inverse piezoelectric effect. The additives such as oleic acid, TCP and etc. are added to Hexane, Hexadecane and Scwaran as base oils. Mass change which is derived from adsorption of additive is measured as frequency shift by the QCM. Using the QCM method influences of temperature and surface materials on adsorption velocity and adsorption strength were examined. In addition, we measured friction coefficient by using a pendulum friction tester and investigated the relation between the friction properties and the absorption behavior considering with the lubricating temperature conditions.
