“…When the shear strength at the interface was higher than those in the soft materials, the adhesive wear can be induced by the shearing of microscopic asperities on soft materials and subsequent adhesion of wear de bris to the interface of hard materials. Such wear char acteristics have been verified in the wear tests for polyethylene sliding against alumina ceramic in [7] and [18], Similar wear behaviors were also observed in the combination of metal-on-polyethylene [19], which pointed out that the polyethylene wear rate is con trolled by the extent of adhesive transfer from polymer to the metal interface. In [19], the wear behavior of polyethylene sliding against metal discs (Ti-6A1-4V al loy with various surface treatment, AISI 316 L stainless steel and Vitallium) were investigated using an annulus-on-disc oscillating tribometer.…”

A numerical approach was proposed to investigate the wear behavior occurred in the artificial hip joints in this paper. In the numerical simulations, the wear coefficients taken from pin-on-disk tests were introduced into the wear analysis model to assess the wear rates of polyethylene acetabular cups against metallic or ceramic femoral heads. For the established material combinations, different values of polyethylene wear rates were obtained respectively, which were not necessarily the realistic one as expected in vivo but could be confirmed after further discussion on the wear mechanism involved in wear tests. Current results indicated that the polyethylene/ceramic couples represented better wear performances than the polyethylene/metal couples. Furthermore, the ratio of wear rates for polyethylene cups against alumina and the metallic femoral heads was 0.5, which agreed well with that deduced from clinical studies or laboratory hip simulators. It is obvious that these comparable wear behaviors observed from clinics or laboratory studies also can be found by means of the numerical simulation.

“…Alumina (Al 2 O 3 ) is one such ceramic particle which presents itself as an excellent choice of a nanofiller, owing to its extremely high hardness retention at elevated temperatures, bio-inertness, ability to enhance the pristine polymer's load-bearing ability, and exceptional corrosion resistance [23,25,26,32,33]. While there are numerous studies on the development of UHMWPE bulk nanocomposites reinforced with alumina, very few studies have reported on reinforcing UHMWPE nanocomposite coatings with alumina.…”

Due to a growing demand for protecting metallic components from wear and tear, polymer coatings are being extensively researched and developed as one of the most effective and efficient solutions to reduce friction and wear in demanding tribological applications. The present study focuses on developing a polymer nanocomposite coating of ultra-high molecular polyethylene (UHMWPE) reinforced with different loadings (0.5, 3, 5, and 10 wt %) of alumina to protect steel surfaces. Wear tests were conducted on the coated samples using a tribometer with a ball-on-disk configuration, sliding against a 440C hardened stainless steel ball as a counterface to evaluate the wear life and the load-bearing capacity of the developed coatings. Micro-indentation, energy dispersive X-ray spectroscopy, scanning electron microscopy, and optical profilometry techniques were used to characterize the coatings in terms of hardness, dispersion of the nanofillers, morphology, and wear mechanisms, respectively. Results showed that the UHMWPE nanocomposite coating reinforced with 3 wt % and 5 wt % of alumina did not fail, even until 250,000 cycles at a normal load of 12 N and a linear speed of 0.1 m/s, showing a significant improvement in wear resistance as compared to the pristine UHMWPE coating.

“…Its main existing applications are in lightweight high-strength fibers, wire and cables, and in the biomedical area, as implants and joint replacement components. However, it is difficult to process pure UHMWPE by injection molding, blow molding, or conventional screw extrusion [1] [2] due to the high viscosity of the molten polymer, which does not allow this thermoplastic material to flow. The poor processability deeply restricts the applications of UHMWPE.…”

Oxidized (GO) and expanded (G-Exp) graphite were employed to prepare composites with ultrahigh molecular weight polyethylene (UHMWPE) matrix using masterbatches of polyethylene with different compositions. The materials and a blend of UHMWPE/HDPE were prepared by extrusion and their properties were evaluated. The effect of carbon fillers on the crystalline structure, thermo dynamic-mechanical (DMTA) and thermal properties (melting and crystallization temperatures) of the composites were discussed. The thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) measurements showed that the addition of masterbatch with GO and G-Exp significantly increased the crystallite size of composites, increasing the temperatures of melting, degradation, glass transition and the degree of crystallinity of polyethylene. DMTA analysis indicated the storage and loss moduli of composites in relation to neat UHMWPE, the blend and UHMWPE/composites. SEM micrographs showed a flatter, continuous and uniform surface meaning a compact lamellar structure. The present work resulted in interesting findings on the effects of GO on the crystalline structures, mechanical and thermal properties of UHMWPE, which can lead to generalizations useful for future work.
