Tribochemical mechanism of the composite package of the n-containing ocmpooundd modified borate and ZDDP in lubrication oil

摘要

The triboloigcal perofrmances of the ocmposite package of the N-containing ocmpound modified borate and zine dialdly dith iophosphats (ZDDP) were investigated using four-ball tester.The results show that the amount of ZDDP additive could affect on the extreme-pressure and antiwear properties of the ocmposite apckage.The synergistic effect mechanism was obsrved when the amount of ZDDP is equal to or more than 0.50wt
