TLDR
In this article, the anti-wear behavior of nanoparticle suspensions in a polyalphaolefin (PAO 6) was discussed and compared using an ultrasonic probe for 2 min. The results showed that the suspensions with 0.5% of ZnO and ZrO 2 had the best general tribological behaviour, exhibiting high friction and wear reduction values even at low deposition levels on the wear surface.About:

Tribofilm formation and mild wear by tribo-sintering of nanometer-sized oxide particles on rubbing steel surfaces
Hirotaka Kato,K. Komai +1 more
TL;DR: In this paper, the authors show that the wear transition behavior depends on the type of supplied oxide and that the mild wear is due to formation of the wear-protective tribofilm on the rubbing surfaces, and observations confirm that the tribo-sintering of the supplied oxide particles.
