Summary: The Fe-based amorphous coating prepared by detonation spraying exhibits excellent wear resistance under dry conditions, with extremely low porosity and high amorphous content contributing to its distinguished performance in sliding wear tests. As loading and sliding speed increase, the wear mechanism shifts from fatigue wear and oxidative wear to delamination wear and oxidative wear.

Summary: The study investigates the effect of thermal oxidation and chemical compositions of oxides on the wear of AZ31B magnesium alloy. Higher temperatures cause thickening of the oxide film layer, emergence of oxide nodules, loss of protective capability, and increased wear rate. The minimum wear rate is found at 200 degrees C while the maximum is at 400 degrees C.

Summary: This study investigated the wear behaviors and mechanisms of 7075 Al alloy under different testing conditions. It was found that the alloy exhibited high wear resistance at high ambient temperature and low load, attributed to the presence of a mechanically mixing layer (MML). The predominant wear mechanisms were adhesive and abrasive wear at room temperature, while oxidative wear and plastic extrusive wear became dominant with increasing ambient temperature and load.

Summary: The study found that the AlCoCrFeNiTi0.5 alloy has better wear resistance than Fe77Ni23 solid solution alloy, Ti-46Al-2Cr-2Nb intermetallic alloy, or a wear-resistant steel AISI 52100, especially under higher loads. The wear rate increases slowly with increasing loads and remains steady at different sliding speeds. The wear mechanisms include abrasive wear, adhesive wear, and oxidative wear.

Summary: In this study, operating parameters were obtained through an engine bench test and thousands of hours of reciprocating lubrication wear tests were conducted on a multifunction wear tester. The wear state of the cylinder liner was divided into mild, medium, and severe wear based on the analysis of wear rate variation under different test parameters. The wear mechanisms of spalling, delamination, and massive spalling were identified for different wear states.

Summary: Magnesium-coated graphene with improved wettability and dispersion was successfully prepared using a novel organic chemical reduction method. The graphene was uniformly distributed in the matrix, and a finer and more dispersed strengthening phase was observed around it. In addition, MgO nanoparticles were formed on the surface of graphene, enhancing the wear resistance of the composites through nano-scale contact and tight interfacial bonding with the substrate.

Summary: This study aims to evaluate the tribological behavior of LPBF-produced aluminum alloy A357 and compare it with conventionally manufactured A357. The results show that LPBF under optimized conditions reduces the wear rate and maintains a comparable coefficient of friction compared to conventional methods.

Summary: The wear behavior of the Mg-3wt.% Zn-0.4wt.% Ca (ZX30) alloy was investigated under dry sliding conditions using AZ31 alloy discs as counterparts. The ZX30 alloy was tested in different states: as-cast, solution-treated, peak-aged, and over-aged. Wear rates and friction coefficients were measured at various loads and sliding speeds. Abrasion and oxidation were identified as the predominant wear mechanisms, with the presence of aluminum oxides indicating adhesive wear. The wear behavior of the ZX30 alloy exhibited a higher susceptibility to oxidative wear compared to other Mg alloys, with a strong influence of observed microstructure.

Summary: The use of lightweight materials is required in automotive and aerospace fields. Magnesium and its alloys possess low density, high mechanical properties, and excellent thermal conductivity. However, they suffer from low corrosion and wear resistances. The combined action of corrosion and wear is critical for these materials.

Summary: The microstructure and corrosion mechanisms of detonation sprayed Fe-based amorphous coating on AZ31B magnesium alloy substrate were studied. The coating presented a typical amorphous structure and had a low porosity. Its excellent corrosion resistance was mainly attributed to its unique disordered structure, uniform chemical composition, and the formation of a uniform passive film on the surface.

Summary: This study investigated the effects of Hf and Al on the properties of 60Ni-40Ti alloy. The addition of Al reduced the precipitation of second phases and improved the microhardness of the alloy. The 54Ni-40Ti-3Hf-3Al alloy showed better tribological performance and formed a stable oxide glaze layer at high temperatures. This research provides a method to enhance the wear resistance of 60NiTi alloy at high temperatures.

Summary: Dry sliding wear tests were conducted on TC11 alloy under different sliding velocities, revealing the formation of tribo-layers on the wear surfaces at different speeds. The formation of these layers depended on factors such as wear debris generation, movement, aggregation, transfer, and tribo-chemistry. Conditions favorable for the formation of tribo-oxide layers included small wear debris and relatively high contact surface temperature, which effectively protected the titanium alloy matrix and reduced wear. The protective effect of the tribo-oxide layer on the matrix improved with a higher content of oxides.

Summary: The paper investigates the impact of punch angle, sheet thickness, and punch speed on the blanking process of DP600 dual-phase steel sheet, focusing on the formation of force and noise. Results show that increasing punch angle reduces blanking force and noise formation, while higher punch speed slightly increases noise without significantly affecting blanking force.

Summary: Plastic materials, especially thermoplastics, are widely used in various industries due to their shaping capabilities. However, the adhesive bonding process faces challenges due to the low surface energy of plastic materials. In this study, PLA sheets were produced using additive manufacturing and joined using different adhesives. The mechanical properties of the joints were examined, and it was found that the strength of the joints is influenced by the adhesive thickness and type.
