“…Compared with 5 wt% CNF-reinforced UHMWPE, the wear rate increased at the presence of a larger CNF concentration (10 wt%). Hard particles [76][77][78][79] 10%-20% Bearing loading capacity 36%-60%…”

“…In addition to CNFs and CNTs, particle reinforcements using other hard particles were reported to be a very promising method for an improvement in the wear performance of UHMWPE [78,79,[89][90][91]. By means of incorporating Ti particles [89], Zirconium particles [78], Pt-Zr quasicrystal [79], natural coral particles [90], and quartz [91] into UHMWPE, the wear rates of the particle-reinforced UHMWPEs reduced from 36% to 60%.…”

The mechanism of this improvement is that these hard particles can effectively take bearing load to protect the polymer matrix and thus improve the wear resistance of UHMWPE.…”

Abstract:As the gold standard material for artificial joints, ultra-high-molecular-weight polyethylene (UHMWPE) generates wear debris when the material is used in arthroplasty applications. Due to the adverse reactions of UHMWPE wear debris with surrounding tissues, the life time of UHMWPE joints is often limited to 15-20 years. To improve the wear resistance and performance of the material, various attempts have been made in the past decades. This paper reviews existing improvements made to enhance its mechanical properties and wear resistance. They include using gamma irradiation to promote the cross-linked structure and to improve the wear resistance, blending vitamin E to protect the UHMWPE, filler incorporation to improve the mechanical and wear performance, and surface texturing to improve the lubrication condition and to reduce wear. Limitations of existing work and future studies are also identified.

“…It is well known that cross-linked UHMWPE has lower wear but the mechanical strength also decreases after irradiation. Introducing quasicrystal into UHMWPE can enhance the wear resistance ability and does not decrease the mechanical strength [158,159]. UHMWPE modified with Schiff base copper complex (Cu (II) chelate of bis (salicylaldehyde) ethylenediamine) and a glycerol-polyethylene microencapsule has lower friction coefficient because of the transfer film of copper on counterface as a result of the self-selective transfer effect [160].…”

Tribological phenomena abundantly exist in living beings, especially in human beings, such as teeth, eyes, bones, skins, heart valves and so on, and it is of meanings to reveal the mechanism of tribology in human body and fabricate artificial biomaterials to replace the damaged tissues to release the pain of patients. Alloys, ceramics and polymers are three uppermost materials used in engineering and some of them play a crucial role in biomedicine. In the paper, we provide an overview of the tribological behaviors of artificial biomaterials including alloys, ceramics and polymers. We aim to provide fundamental mechanistic and applications of tribological biomaterials, while emphasizing the advantages and disadvantages of various kinds of tribological biomaterials. Finally, some challenges and the potential promising breakthroughs are also succinctly highlighted in this field.

Abstract. Mechanical alloying was applied to form a decagonal phase in the Al--Cu--Cr system. were mechanically alloyed in a planetary ball mill. Annealing in the temperature range of 500 to 550 C results in the formation of binary and ternary compounds including the decagonal quasicrystalline phase that was found to be stable at least up to 800 C and was present in various amounts in all investigated alloys. No icosahedral quasicrystalline phase was found in the samples. The maximum content (95 vol%) of decagonal quasicrystalline phase was observed for Al 69 Cu 21 Cr 10 compound annealed at 635 C. Further increase in the annealing temperature results in the quasicrystalline phase transformation into w-Al 65 Cu 25 Cr 10 phase, which is an approximant phase to icosahedral quasicrystal.
