With downsizing of automobile electrical components, the sliding conditions of gears and clutches have become more severe. As a response to this, PTFE powder is used in lubricating oils as an additive. However, the relationship between the properties of PTFE powder and the friction characteristics of lubricants containing PTFE powder has not been clarified yet. In this study, we measured the friction characteristics of a lubricant by varying the powder concentration and particle size on a pin-on-disk friction tester. As a result, the following two findings were obtained; 1. As the powder concentration increases, the coefficient of friction decreases. 2. At a high powder concentration, the lower the lubricating oil liquidity, the lower the coefficient of friction.
