Abstract: From the point view of molecular design, a kind of nitrogen-containing heterocyclic borates as lubricant additive is synthesized. The tribological properties of nitrogen-containing heterocyclic borate as additive in liquid paraffin are investigated on a four-ball tester. The morphologies of the worn scars are observed by means of scanning electron microscopy. The results show that the load-carrying capacity and the antiwear performance of the liquid paraffin with the additive added are improved, and wear scar diameter is decreased in comparison with the base oil.

Key words: nitrogen-containing heterocyclic borate; preparation; tribological property
