Summary: Different proportions of WC/Cu particle-reinforced Co-based composite coatings were prepared by laser cladding on Inconel 718 superalloy, and their tribological properties against Si3N4 ball at room temperature and 600 degrees C were investigated. The results showed that the addition of WC and Cu improved the microhardness and tribological properties of the composite coatings.

Summary: Epoxy composite coating systems are commonly used in applications to protect components from corrosive media, but their use in demanding tribological applications is limited. Researchers have attempted to enhance the tribological properties of these coatings by utilizing different types of micro/nano-sized fillers.

Summary: By fabricating Ni/Si3N4 composite coatings with high particle content, achieving ultra-low friction coefficient in water sliding against Si3N4 ball is possible. The essential conditions for this include the formation of smooth contact interface and the presence of silicon hydroxide as a tribo-chemical product. This behavior of ceramic composite coating may provide a new approach for low energy loss water lubrication systems.

Summary: This study compared the use of carbon matrix composite (CMC) wear-resistant plate and common wear-resistant (CWR) plate in replacing silica in rubber formula. The results showed that CMC wear-resistant plate exhibited a high friction coefficient and low wear rate in the mixing process of silica compound, while the opposite trend was observed for carbon black compound. The experimental results suggested that CMC wear-resistant plate is more suitable for a silica mixing process, and its increasing friction coefficient with decreasing wear rate can improve the importance of effective friction in mixing and prolong the service life of wear-resistant plate.

Summary: Composite coatings (Ni60-Ti3SiC2) prepared by laser cladding on 304 stainless steel exhibited significantly improved hardness and excellent tribological properties at high temperatures. The presence of small-sized hard phases for fine-grain and dispersion strengthening, along with the addition of Ti3SiC2 lubricant, contributed to the enhanced wear resistance and friction reduction observed.

Summary: This paper presents real-time in situ measurements of the tribological behavior of coated surfaces, aiming to understand the failure mechanisms and improve the wear and friction resistance of coatings. Two different test systems, a microtribometer and a ball on disc tribometer, were used to test DLC and TiN coatings on tool steel substrates. The results showed delamination failure of the DLC coatings in both test systems, and a new rotating scratch test was also introduced.

Summary: Inspired by natural nacre, researchers developed hierarchically structured graphene oxide (GO) composite coatings reinforced with different concentrations of polyvinyl alcohol (PVA). The inclusion of PVA significantly improved the tribological performance of the GO coating on 304 stainless steel, reducing friction coefficient and wear rate.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear 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: This study proposes a simplified strategy for exfoliating multilayer-MXene via water-molecules-assisted intercalation approach, thereby limiting its use as a lubricant additive. MXene and tetradecylphosphonic acid (TDPA)@MXene sheets were prepared as lubricant oil additives by chemical etching and surface modification. The as-prepared additives added to PAO8 showed reduced friction and wear resistance at contact pressures less than 1.4 GPa, attributed to the iron-oxide and FePO4 tribochemical reaction film and lower interlaminar shear between the MXene layers.

Summary: The experimental results show that under dry friction conditions, the texture structure has a significant impact on the friction coefficient and wear resistance of diamond coatings. For the same type of textures, the larger the texture surface area, the lower the friction coefficient. Elliptical textures can capture abrasive particles and reduce the friction coefficient of diamond coatings.
