“…The surface of BN30Gt40 demonstrated scale-like protrusions, which was a result of the formation of UHMWPE transfer film as well as the supportive filler network consisting of BN and Gt. 81 The formation of this typical structure mitigated the direct damage to the sample surface, ultimately improving the friction and wear performance.…”

In this work, blended composites with ultra‐high molecular weight polyethylene (UHMWPE) as matrix polymer, α‐zirconium phosphate (α‐ZrP) as filler, and sodium polyacrylate (PAANa) as compatibilizer were prepared. The interfacial interaction between PAANa as a compatibilizer and the components of α‐ZrP/UHMWPE was studied by molecular dynamics simulation. The friction and wear behavior of the GCr15 ball/composite friction pair under seawater lubrication under different loads were explored, and the friction and wear mechanism were analyzed. The results show that PAANa as a compatibilizer can effectively improve the interfacial interaction force between components of PAANa/α‐ZrP/UHMWPE composites. The composites exhibited different trends regarding the relationship between tribological properties and α‐ZrP content under various loads. The wear mechanism of composites under low load is mainly represented by extrusion deformation. With the increase of load, the wear mechanism of composites gradually changed into adhesive wear and abrasive wear (depending on the content of α‐ZrP). This work provides a theoretical basis for preparing and applying other α‐ZrP/polymer blend composites.

A hybrid of halloysite nanotubes decorated with titanium dioxide nanoparticles (HNTs@TiO2) was synthesized by the sol–gel method and then mixed with ultra‐high molecular polyethylene (UHMWPE) by melt compounding to enhance its wear resistance properties. The incorporation of HNTs@TiO2 increased the crystallinity as well as the hardness of UHMWPE nanocomposites, which benefited less prone to plastic deformation during the friction process. In addition, the UHMWPE/HNTs@TiO2 maintained a high ductility character with a slight decrease in tensile strength compared to pure UHMWPE. With the addition of 3 wt% HNTs@TiO2, the UHMWPE nanocomposite achieved a remarkably low friction coefficient of 0.073 and a reduced wear rate of 6.67 × 10−6 mm3/N·m. These values represented a 32.4% decrease in friction coefficient and a 43.9% decrease in wear rate compared to pure UHMWPE. The improvement in wear resistance was due to the dislodged TiO2 and HNTs had good synergistic rolling effects at the counterface. Furthermore, the wear scan morphology observation revealed that the transferred HNTs@TiO2‐based materials could help to improve the quality of the tribofilms, which alleviated the abrasive wear from the metallic counterpart. This work offers a feasible way to enhance the wear resistance of UHMWPE nanocomposite without sacrificing the high ductility for expanding its engineering applications.Highlights TiO2‐decorated halloysite nanotubes were synthesized by the sol–gel method. The addition of HNTs@TiO2 maintained the high ductility character of UHMWPE. The UHMWPE composite with 3 wt% HNTs@TiO2 had the best wear resistance.
