Summary: This study modified high-nitrogen austenitic stainless steel using a mechanical-thermal treatment (MTT) that included friction processing and subsequent electron beam processing. The MTT resulted in the formation of a highly dispersed microstructure with nanodispersed phases and improved properties, including increased microhardness, crack resistance, yield point, and wear resistance. The near-surface layer of the steel after MTT showed potential for biomedical applications.

Summary: Temperature has a significant influence on the friction performance of (Cr, V)N coatings. Below 600℃, the coatings exhibit a high friction coefficient but mild wear; above 700℃, increased oxidation reduces adhesion, leading to a significant increase in wear rate with temperature rising.

Summary: The study investigated the effects of Si-ion implantation on CrN/ZrN multi nanolayers, revealing moderate radiation-tolerance and changes in composition homogeneity and structure crystallinity within the ion range. The asymmetric distribution of Si negative ions and the formation of Si-rich interfaces were attributed to the strong Si-Cr bindings and differences in displacement energies of ZrN and CrN. Wear resistance and friction coefficient enhancement were observed in the nanoscale coating due to the presence of amorphous Si particles from the interfacial areas.

Summary: The study comprehensively investigates the contributions of lattice distortions to superlubricity in solute-doped twisted bilayers, revealing that the changes in interlayer interactions induced by layer corrugations are key to optimizing lubricity and matching experimental friction coefficients. The evolutions of band structures show an exponential relationship between band edge width and layer deformations, providing a pathway for accelerated development of advanced superlubricity materials via lattice distortions.

Summary: In this study, Cr/CrN/Cr/CrAlN multilayer films with various thickness were deposited on TC4 titanium alloy substrates using a cathodic arc system. The effects of film thickness on microstructure, mechanical properties, tribological properties, and tensile properties were investigated. The results showed that increasing film thickness led to an increase in the number of large particles on the surface and residual stress. The hardness difference was not significant, but the best bonding and crack extension resistance were achieved at 54 cycles. The multilayer films exhibited good wear resistance and increased tensile strength compared to uncoated samples.

Summary: The cathodic arc evaporation deposition method was used to form Al-Cr-B-N coatings, and the effect of nitrogen pressure and substrate bias voltage on the properties of the coatings was investigated. The coatings exhibited a mixture of h-AlN and c-CrN phases with a crystallite size of about 4 nm, as well as an amorphous BN phase. Coatings deposited under p(N2) = 4 Pa and U-B = -100 V showed the highest resistance to wear and corrosion among the tested coatings.

Summary: C-Cr-Mo-V martensitic steel with adjusted carbide characteristics and matrix microstructure through controlling forging ratios can improve its hardness, toughness, and wear resistance. The increase in forging ratio leads to more homogeneous distribution of primary carbides and an increase in secondary carbides, resulting in enhanced pinning effect on grain boundaries and refinement of prior austenite grain. The hardness and impact toughness increase with the forging ratio, benefiting from the refined carbide and prior austenite grain. The wear resistance of the experimental steel is enhanced when the forging ratio reaches 6 or 12 due to the higher content and finer size of primary carbides under smaller forging ratios, and the refinement of martensite matrix, uniform distribution of primary carbides, and precipitation of secondary carbides under larger forging ratios.

Summary: This article presents comparative tests of contact strength and tribological wear resistance of polymer sliding materials of the polyamide group. The aim of this work was to study Shore hardness, indentation hardness, modulus, creep, relaxation, Martens hardness and sliding wear resistance of two commercial materials. The research indicates that it is not hardness but the ability to form a sliding layer on the friction surface that determines the suitability in the anticipated operating conditions.

Summary: A comparative study was conducted on (Cr1-xAlx)(2)O-3 and (Cr1-xAlx) coatings with different Al contents (x = 0, 0.5, and 0.7) regarding their structural, mechanical, and tribological properties. It was observed that higher Al content resulted in a mixed structure of cubic and minor amorphous phases in the coatings. Additionally, the increase in Al content led to a decrease in hardness and residual compressive stress. Furthermore, the study revealed higher wear rates for the coatings under high-temperature conditions.

Summary: This paper proposes a method for identifying the elastic-plastic properties of coating materials on an elastic-plastic substrate based on nanoindentation analysis of the coating/substrate system. By integrating a trust-region reflective optimization algorithm with finite element analysis and the Jo center dot nsson and Hogmark model, the method accurately predicts the properties of the coating materials and modifies the predicted load-displacement curve to fit the experimental nanoindentation curve. Experimental tests on a CrN film/Martensitic stainless steel substrate system verified the method and obtained Young's modulus, yield stress, and work hardening exponent of the film. Sensitivity analysis demonstrated that variations in the elastic-plastic properties of the steel substrate have a significant impact on the loading and unloading parts of the load-displacement curve compared to those of the CrN coating.

Summary: In order to develop a hybrid process for producing TiC wear coatings on 316L, the interfacial reactivity between stainless steel and titanium needs to be understood. Through systematic comparisons of diffusion couples with increasing complexity, the formation mechanisms of interfacial structures were revealed. The growth of FeTi and Fe2Ti intermetallics was shown to be non-diffusion controlled, acting as diffusion barriers for chromium and carbon traps, resulting in a complex layered structure at the interface.
