Summary: This study focuses on the composite coating made from ultrahigh molecular weight polyethylene (UHMWPE) and diabase filler obtained by flame spraying. Different percentages of diabase (10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.%) were used as fillers. The study examined the coating using various techniques and found that diabase does not negatively impact the chemical structure of UHMWPE and its addition increases the wear resistance and microhardness of the coating.

Summary: The content of high-density polyethylene (HDPE) has a significant influence on the structure and mechanical properties of ultrahigh molecular weight polyethylene (UHMWPE)/HDPE blend fibers. The addition of different contents of HDPE leads to a decrease in molecular entanglement and an improvement in the melt processability of UHMWPE. Moreover, UHMWPE/HDPE fibers with an HDPE content of 40 wt% exhibit higher molecular chain orientation, greater crystallinity, and thinner grain size, resulting in the best mechanical properties. This study reveals the effect mechanism of HDPE content on the preparation and properties of UHMWPE/HDPE fibers, providing an effective and universal strategy for manufacturing high-strength fibers with the melt spinning method.

Summary: The mechanical properties of ultra-high molecular weight polyethylene (UHMWPE) composites for acetabular cup liner are improved by adding hydroxyapatite (HAp) and carbon nanotubes (CNT) with improved adhesion through surface modification. The dispersion and interfacial adhesion of functionalized HAp and CNT with the polymer matrix are enhanced, resulting in increased reinforcement fraction and improved bulk mechanical properties. These functionalized composites also maintain cytocompatibility, making them suitable for use as acetabular cup liners for hip joint arthroplasty.

Summary: A facile catalytic approach utilizing POSS-modified MgCl2-based Ziegler-Natta catalyst was reported for preparing fine UHMWPE particles, resulting in the synthesis of nascent UHMWPE with less entangled state and fine particle size. This combination of structural advantages significantly improved the toughness/stiffness/strength balance of nascent UHMWPE, especially achieving an impact strength of 113.6 kJ/m(2) with a relatively low molecular weight.

Summary: The tribological characteristics of ultra-high molecular weight polyethylene (UHMWPE) under unsaturated lubrication of water and brine were studied. The effect of load and speed on the friction properties of UHMWPE were analyzed. The results showed that the lubrication form of UHMWPE gradually transited from saturated lubrication to unsaturated lubrication with the increase in load or speed. Under brine-unsaturated lubrication, the anti-friction property of UHMWPE was better than that in water-unsaturated lubrication at high speed. The wear resistance of UHMWPE also varied under different lubrication conditions.

Summary: Ultra-high-molecular-weight polyethylene (UHMWPE) wear and particle-induced osteolysis contribute to the failure of total hip arthroplasty (THA) and total knee arthroplasty (TKA). Highly crosslinked polyethylene (HXLPE) has been developed to reduce wear, but its benefits are more prominent in THA than in TKA.

Summary: The results present an investigation of the modified surface of a copper substrate with titanium ions, including phase composition, structure, and morphology. It was found that intermetallic phases of the Cu-Ti equilibrium diagram are formed in the surface layer during the treatment. A multi-level micro- and nanoporous structure is also observed. The study shows that the structure-phase state and morphology of the copper surface directly affect the thermocycler resistance and adhesion of the Zr-Y-O coating. The thermocyclic resistance of the Zr-Y-O coating increases significantly, and the adhesion is greatly improved when the substrate surface is treated with titanium ions for 6 minutes.

Summary: This article discusses the improvement of mechanical properties and protection of glass materials in optical systems used in space vehicles. It suggests using multi-phase nanocomposite shock-resistant transparent coatings made of indium-tin oxide (ITO) on the surface of glass plates. Research shows that ITO coatings remain transparent in the visible spectrum and consist mainly of nanocrystalline In2O3 phase. These coatings demonstrate resistance to shock impact and can reduce crater density on glass surfaces caused by solid microparticles. The reduction in crater density is attributed to the reinforcement of the glass surface layer by the nanocomposite coating and the dissipation of energy through normal shock waves.

Summary: The paper examines a magnetron sputter-deposited multilayer, multicomponent Al-Si-N/Ni/Al-Si-N coating with enhanced corrosion resistance. It investigates the phase and elemental composition of the coating and its structural layers. The results reveal that all layers of the coating have a columnar structure, with the Al-Si-N coating exhibiting a nanocrystalline structure and the nickel layer showing a finely crystalline structure. X-ray diffraction analysis confirms the presence of AlN and Si3N4 phases with a hexagonal closed packed crystal structure in the Al-Si-N layer. Corrosion tests demonstrate that the Al-Si-N/Ni/Al-Si-N coating provides higher corrosion resistance compared to uncoated specimens.

Summary: The paper presents the results of tensile and impact bending tests on a high-nitrogen austenitic stainless steel at temperatures ranging from -196 to 20 degrees C. The steel exhibited a ductile-to-brittle transition, but still maintained high strength and ductile fracture behavior at low temperatures. The microstructure and fracture surfaces were examined using electron microscopes and X-ray diffraction. The study revealed that brittle fracture was induced by epsilon-martensite formation, along with the presence of internal stresses at the grain boundaries due to nitrogen segregation and lattice volume changes.

Summary: This research focuses on the formalized approach to dental material selection (DMS) in manufacturing removable complete dentures (RDC). Three types of commercially available polymethyl methacrylate (PMMA) grades, processed by an identical Digital Light Processing (DLP) 3D printer, were compared. The developed DMS procedure employs the extended VIKOR method to conduct a fully fledged analysis of alternatives, taking into consideration the prosthesis design and its production route. The proposed approach has the potential to enhance the efficiency of prosthetic treatment by optimizing the DMS procedure.

Summary: The tribological performance of PI- and PEI-based nanocomposites reinforced with chopped carbon fibers (CCF) and additionally loaded with halloysite nanotubes (HNTs) and carbon nanotubes (CNT) was studied. The PEI/10CCF/1HNT nanocomposite exhibited the highest wear resistance and absence of microabrasive damage in the point contact. A tribological layer was formed on both PI- and PEI-based nanocomposites in the linear contact, governed by the development of creep and mixing processes. The PEI-based nanocomposite loaded with CCFs and HNTs is a promising inexpensive material for metal-polymer friction unit components due to its higher manufacturability and lower cost.

Summary: This study investigates the formation and adherence characteristics of tribofilm on the wear track surface of antifriction PI- and PEI-based composites, as well as a transfer film on a steel counterface. It is found that PTFE nanoparticles melted and coalesced into micron-sized porous inclusions during hot pressing. The dimensions of these inclusions were larger in the PEI matrix compared to the PI matrix, hindering their effectiveness as uniformly distributed nanofillers.
