Abstract

<p>The objective of this study is to reveal the relationship between frictional behavior and the compatibility of rubber and lubricants in order to understand boundary lubrication mechanism of rubber. To achieve this, sliding experiments under boundary lubrication conditions were conducted using two acrylonitrile-butadiene rubbers (NBR) with the different polarity. In addition, the direct observation of sliding surface using a total reflection method was conducted in order to observe the process of generating a lubricant film. Even if the hydrodynamic lubrication was not enough to prevent a direct contact, lubricants played a role of lubricant film and the friction coefficient decreased during sliding. It was found that this was caused by swelling and deswelling of rubbers. It was concluded that, as swelling depended on the combination of rubber and lubricants, the compatibility between the rubber and the lubricant had the significant influence on the process of generating a lubricant film.</p>
