Effect of Amide Molecular Structure on Tribological Properties of Thermoreversible Gel Lubricant

Thermoreversible gel lubricant (TR gel lube) has been developed as a unique new lubricant. TR gel lube contains a high percentage of aliphatic amide as a gel agent in the base fluid. It is able to repeatedly change from a gel state to a liquid state at the melting point. Therefore, the new lubricant...
