资源简介：
The feasibility of CuP as a multifunctional additive in lithium grease was evaluated for the first time. The
experimental results indicated that the CuP significantly enhanced the friction reduction, antiwear properties,
extreme pressure capabilities, and antimicrobial characteristics of lithium greases. The SRV test results suggested
that the optimal tribological properties were obtained by adding 3 wt% of CuP to lithium greases, resulting in a
decrease of the friction coefficient and wear volume by 28.25% and 34.98%, respectively. The four-ball results
confirmed that the extreme pressure performance of the lithium grease with 3 wt% CuP was enhanced by a factor
of 3.17. The bacterial inhibition rate of lithium grease with 3 wt% CuP was higher than 99.98%. The lubrication
mechanism and antimicrobial mechanism was explained.
