Nanomaterials are widely used as promising additives in tribology. In this study, large cadmium-based phosphate (CdP) microspheres assembled from nanosheets were synthesized, and the tribological performance and anti-wear mechanism of the CdPs as additives in lubricating oils were investigated using a reciprocating ball-on -disc tribometer and surface characterization techniques. Oxygen-free oil with CdP significantly reduced the friction coefficient (COF) and wear rate (WR) of TA5 titanium alloys. Compared with pure polyalphaolefin 8 (PAO8), lubrication with PAO8 containing 25 wt% CdP reduced...
