Summary: Metal heat treatment can improve the performance of Ti6Al4V titanium alloy. In this study, Ti6Al4V titanium alloys are manufactured by heat-treating electron powder bed fusion, and the friction and wear properties of samples after different heat treatments are analyzed. The results show that HT3 has the smallest coefficient of friction but the largest amount of wear, while HT9 has a smaller amount of wear compared to HT3.

Summary: The study found that under different sliding conditions, dimples defined by nanosecond laser exhibited the lowest steady-state coefficient of friction, while in Hank's solution, lines and crosshatching showed better frictional characteristics after running-in and the removal of bulges around the laser textures. In terms of wear resistance, low-density lines pattern and particularly dimples were the most promising in contact situations likely to occur during starved/dry-lubrication conditions.

Summary: The effect of thermal oxidation on the surface of a Ti6Al4V alloy was evaluated in terms of increasing hardness and improving its tribological values. Significant changes in the alloy morphology were observed starting at 650 degrees C, with the formation of the rutile crystal phase. A maximum hardness of 13.98 GPa was achieved at 750 degrees C, along with a reduced wear rate and friction resistance. The heat treatment at 750 degrees C improved the tribological properties and increased the hardness of the alloy.

Summary: The friction stir weldability of Ti6Al4V T-joints was investigated in this study. The influence of tool and welding parameters on weld quality was studied, and the joints' mechanical strength was assessed for future applications. Co-based FSW tools wear was characterized by monitoring wear during tests. The defectivity of the welds was analyzed using cross-section macrographies. Regardless of the welding parameters and tools used, internal voids were avoided, and a suitable weldability window was identified. Microstructure observations confirmed temperatures below the fl-transus point even in the nugget zone, ensuring optimal mechanical strengths for the joints. However, issues such as section thinning, kissing bond defects, and tool wear must be addressed to prevent low elongation at break and ensure the mechanical strength of the joints.

Summary: This study investigates the effect of ceria (CeO2) content on the microstructure, hardness, and wear properties of a titanium metal matrix composite (Ti6Al4V-ZrO2-CeO2) cladding. The addition of CeO2 refines the microstructure and promotes the in-situ formation of hard ceramic compounds, leading to significant changes in hardness, coefficient of friction, fracture toughness, and wear resistance of the cladding.

Summary: The fully lamellar Ti6Al4V alloy was severely deformed using high pressure torsion (HPT) process, resulting in significant improvements in micro-hardness and grain size. The tribological properties of the alloy were investigated for the first time, showing a notable decrease in friction coefficient and specific wear rate with an increase in HPT revolutions. Overall, the HPT processed Ti6Al4V alloys displayed great potential in structural applications due to their enhanced mechanical and tribological properties.

Summary: The present study investigated the wear and friction behavior of Ti6Al4V against alumina using a pin-on-disc tribometer at room temperature. The wear rate increased continuously with load and showed transition behavior with respect to sliding velocity. Minimum friction was observed at intermediate sliding velocities. The study found that load had a more significant influence on wear rate, while the opposite was true for the coefficient of friction. A wear model was predicted and confirmed through subsequent tests. The wear mechanism involved adhesion, abrasion, oxidation, and delamination wear, with the formation of Ti8O15 attributing to lower wear rates at higher loads and velocities.

Summary: Surface texturing and protective coating were utilized to improve the surface properties of Ti6Al4V bio-alloy. The hierarchical grooved structure reduced the coefficient of friction and the embedded sub-patterns inhibited abrasive and delamination wears. The zirconia coated groove sample exhibited superior corrosion resistance due to the laser induced titanium oxide layer and the greater hardness of the zirconia film.

Summary: Experimental data on the structure, chemical composition, and wear resistance of a titanium alloy Ti6Al4V after pulsed laser treatment show that rapid solidification forms a new microstructure, affecting the surface's topography. Different laser pulse parameters can lead to desired surface texture, and femtosecond and picosecond pulse treatment creates micro/nano structures with good wear resistance. Nanosecond laser treatment results in an extended metal-oxide foam surface with transformed alpha-Ti phase.

Summary: In this study, CoCrMo alloy surfaces were subjected to powder-pack boriding at 950°C for 5-hour and 7-hour treatment periods. The boride layers composed of CoB, Co2B, CrB, and Co2MoB2 phases significantly increased the nanohardness values and elastic moduli. The increased surface hardness and high temperature stability of boride layers resulted in a significant increase in the wear resistance of CoCrMo alloys at different temperatures.

Summary: Coatings with a thickness of 40-50 μm were formed on Ti6Al4V titanium alloys using plasma electrolytic oxidation (PEO) with the addition of graphene oxide. The study investigated the effect of graphene oxide concentration on the properties of the PEO coatings, including thickness, roughness, hardness, surface morphology, structure, composition, and tribological characteristics. It was found that the addition of graphene oxide led to a slight decrease in friction coefficient and a significant reduction in wear rate. Delamination of the coatings during wear was slowed down with increasing graphene oxide concentration.

Summary: The study focused on the interaction between a nickel base superalloy used as a friction processing tool and Ti6Al4V alloy metal for in-situ synthesis of intermetallics. Sever abrasion-adhesion wear was observed on the tool's pin areas, while a mechanically mixed layer protected the shoulder. The formation of titanium enriched mechanically mixed layers and fine-crystalline transition layers containing high tungsten content were observed on the tool's surface.

Summary: Graphene oxide (GO) was incorporated into polyvinyl alcohol (PVA) hydrogel to improve its mechanical and tribological performances for potential articular cartilage replacement application. The effects of load, sliding speed, diameter of counterface, and counterface materials on the frictional coefficient of PVA/GO hydrogels were discussed. A low friction coefficient (similar to 0.03) was obtained from PVA/0.10wt%GO hydrogel natural cartilage counter pair.
