Conclusions As an anti-wear catalytic agent, CHP reliably distinguishes among lubricants with respect to anti- wear qualities in tests on a four-ball friction machine and the Cameron-Plint tribometer. By screening various compounds, it was possible to identify several quality classes of potential anti-wear additives for engine lubricants as replacements for zinc dialkyldithiophosphate: Heterocycles with Sulfur/Nitrogen atoms Esters with Nitrogen atoms (CHON) Silanes/Siloxanes
