The Mechanism of Glycerol Superlubricity

09.05.2016 Aydar Akchurin 277 Views
Glycerol is a highly viscous liquid, generating friction coefficient of 0.1 and up for bearing steels in boundary lubrication. In full film EHL, pure glycerol generates high friction as well and therefore is rarely used […]
