Summary: Al0.5CoCrFeNi high-entropy alloy particles reinforced aluminum matrix composites (HEAps/AMCs) with various reinforcement additions were fabricated and their wear properties were investigated. It was found that a moderate range of reinforcement exhibited lower coefficient of friction and wear rate compared to the matrix alloy. The HEA particles hindered plastic deformation and improved the crack resistance of the composites through tight interface and interaction with dislocations.

Summary: Electrodeposition technique is an effective method for preparing functional coatings with improved tribological behavior. Ni-MoS2, Ni-SiC, and Ni-MoS2/SiC composite coatings were successfully prepared on 2218 aluminum alloy, showing enhanced friction reduction and wear resistance. However, the specific performance varied among the different composite coatings.

Summary: Electrodeposition was used to prepare nickel graphene oxide (Ni-GO), nickel silicon carbide (Ni-SiC), and nickel graphene oxide/silicon carbide (Ni-GO/SiC) composite coatings on a 2218 aluminum alloy substrate. The composite coatings exhibited dense and defect-free microstructures, strong bonding with the substrate, and significantly increased microhardness. The friction coefficient and wear rate of the composite coatings were lower compared to the substrate. Among the composite coatings, the Ni-GO/SiC composite coating showed the best overall tribological performance.

Summary: This study investigates the electroless composite coatings with added SiC particles. The results show that the composite coatings fabricated with 1 g/l SiC concentration exhibit higher hardness value. Subsequent heat treatment at 450 degrees C improves the mechanical and tribological properties of the coatings. However, heat treatment at a higher temperature (650 degrees C) leads to a decrease in the coating's properties.

Summary: Ni?SiC composite coatings were successfully deposited on interior surfaces of cylinders using the circulating-solution electrodeposition technique on a newly-designed composite electroplating apparatus. The improved dispersibility of SiC particles, enhanced hardness, protection from NiO layer and SiC reinforcements, along with friction-induced microstructure changes underneath the tribo-surface, contributed to the excellent wear resistance of the coatings. The dominant wear mechanism was found to be oxidative wear, with decreasing friction coefficient and wear rate as SiC content increased.

Summary: The application of C/C composites in finger seals is a solution to the problem of seal wear due to its excellent tribological and mechanical behaviors. The designable characteristics of composites, such as density and orientation, greatly influence the tribological properties and service life of sealing materials. A study was conducted using a reciprocating tribo-tester to investigate the effects of material density, fabric orientation, load, and sliding velocity on the tribological properties and wear mechanism of the C/C composite. The results show that perpendicular orientation and higher density provide better tribological properties and lower wear rates.

Summary: The study used the thermal-diffusion chromizing method to enhance the wear resistance of traction wheels in orchard transport. A uniform and dense chrome coating was formed on the surface, resulting in a significant decrease in friction coefficient and wear loss. Microstructure study and finite element analysis identified the synergetic effect between fatigue wear and abrasive wear as the cause of wear failure.

Summary: Titanium carbide (TiC) thin films were deposited on a copper substrate using radio frequency magnetron sputtering with argon gas plasma. The effects of time and temperature at a constant RF power on the structural and tribological properties were investigated. The films exhibited crystal structures with preferential orientations of (111) and (200) planes. The lowest thin film roughness of 19.797 nm was observed at an RF power of 200 W, sputtering time of two hours, and temperature of 80 degrees C. FTIR spectra showed the formation of a Ti-C bond. Different samples had varying wear volumes, with the lowest being 5.1 x 10(-3) mm(3) and the highest being 9.3 x 10(-3) mm(3).

Summary: In this study, graphene oxide (GO) reinforced high-entropy alloy (HEA) composites with different GO contents were synthesized and their surface hardness and wear resistance were comparatively investigated. The results showed that an appropriate amount of GO significantly improved the surface hardness and wear resistance of the materials, but excessive GO content resulted in decreased hardness and increased friction coefficient.

Summary: The TiC/graphene/graphite/Ti6Al4V composite coating was prepared using laser cladding, showing improved wear resistance and changing wear mechanisms under different loads, transitioning from abrasive and oxidation wear to delamination, fatigue, and oxidation wear. The in-situ reaction between graphene and titanium formed feathery TiC, enhancing the coating's tribological behavior.

Summary: Laser processing technology was used to prepare triangular textures with different area occupancies on the surface of 4Cr10Si2Mo valve steel, and then the steel was subjected to salt bath nitridation and oxidation. The effects of triangular texture on surface stress, hydrodynamic pressure, and friction were explored using simulation technology. The results showed that the wear resistance of the steel significantly improved after the composite texture treatment.

Summary: The present study focused on fabricating silicon carbide particle reinforced AA7075 composites using Friction Stir Processing (FSP) and analyzing the impact of processing, particle addition, and tool rotational speed on mechanical and wear properties. Results indicated that reinforcement addition improved microhardness and wear resistance but led to decreased ductility and tensile strength in the material. Tool rotational speed showed a direct relationship with the tested mechanical and wear properties, with adhesive wear being the prominent wear mechanism observed. These composites have potential applications in industries like automotive, defense, and aerospace.

Summary: This study investigated the frictional behavior of Z-yarn during implantation into a preform to reduce wear and tear. By designing a guiding array clamping device and a tensile force sensor, changes in tensile strength of Z-yarns at different implantation positions and times were studied. Results showed that the use of unadulterated solvent dimethyl silicone oil and a tension control system effectively reduced wear and increased the continuous implantation number of Z-yarns.
