Effect of Surrounding Gas on Cavitation in EHL

Relationship between cavitation in elastohydrodynamic lubrication and surrounding gas was investigated in order to understand lubrication in various gas environments. Lubricated point contact sliding test was conducted in a sealed chamber. Gases used were air, carbon dioxide, argon and helium. It wa...
