“…Corrosion rate in acid solution is higher because the passive film is less compact, porous, and unstable. Li et al [59] used a high-frequency push-pull fatigue testing machine to report the effect of fretting on the fatigue performance of Ti-6Al-4V and Ti-10V-2Fe-3Al alloys. For comparative analysis of the fretting effect on the fatigue performance of the different titanium alloy, the author obtained both plain and fretting fatigue curves.…”

High-entropy alloys (HEAs) are materials of high property profiles with enhanced strength-to-weight ratios and high temperature-stress-fatigue capability as well as strong oxidation resistance strength. HEAs are multi-powder-based materials whose microstructural and mechanical properties rely strongly on stoichiometry combination of powders as well as the consolidation techniques. Spark plasma sintering (SPS) has a notable processing edge in processing HEAs due to its fast heating schedule at relatively lower temperature and short sintering time. Therefore, major challenges such as grain growth, porosity, and cracking normally encountered in conventional consolidation like casting are bypassed to produce HEAs with good densification. SPS parameters such as heating rate, temperature, pressure, and holding time can be utilized as design criteria in software like Minitab during design of experiment (DOE) to select a wide range of values at which the HEAs may be produced as well as to model the output data collected from mechanical characterization. In addition to this, the temperature-stress-fatigue response of developed HEAs can be analyzed using finite element analysis (FEA) to have an in-depth understanding of the detail of inter-atomic interactions that inform the inherent material properties.

“…Ti-6Al-4V (TC4) titanium alloys have high specific strength, optimal toughness, and corrosion resistance [1][2][3] and have been widely used for the manufacture of aircraft landing gear, engine compartment, tail wing, and main bearing rotating structural components of the helicopter rotor system [4][5][6] . A typical low-cost proximity β-titanium alloy (Ti-10V-2Fe-3Al or TB6) can reduce the mass of air vehicles by approximately 20% [7][8][9] compared to a TC4 titanium alloy in aeronautic manufacturing. However, aircrafts are often impacted by flying stones during takeoff and landing, and their structural components are highly susceptible to loss of efficacy due to friction and wear under the long-term accumulation effect 10 .…”

Superhydrophobic surfaces of conventional Ti-6Al-4V (TC4) titanium alloys facilitate drag reduction and anti-wear. However, the economical fabrication of a wear-resistant superhydrophobic Ti-10V-2Fe-3Al (TB6) titanium alloy for application in modern aerospace equipment remains to be achieved. Here, an efficient wear-resistant superhydrophobic TB6 titanium alloy surface using commercially available materials and processing equipment was fabricated through nanosecond laser texturing and facile chemical modification. The wettability of textured surfaces, including line and grid patterns, ablated at different laser scanning intervals were investigated and analyzed in terms of surface morphology and chemical composition. Moreover, the mechanisms of coefficient of friction changes on different surfaces under dry and water sliding conditions were studied based on surface morphology and wettability. Under dry sliding and water lubrication conditions, the average coefficient of friction of the prepared superhydrophobic surface can be reduced by 29% and 74%, respectively, compared with that of the original hydrophilic surface.

“…However, its poor wear resistance, unstable and high friction coefficient, low thermal conductivity and bearing capacity limit its further application to a great extent [4,5]. Especially in the aviation field, when titanium alloy is used as structural components in turbine blades and disks, compressor blades and disks, and other systems, the contact surface often causes fatigue damage due to fretting wear, resulting in fracture failure of materials [6,7]. Therefore, it is necessary to modify the surface of titanium alloy to enhance its fretting wear resistance under severe conditions.…”

As an excellent light metal material, titanium alloy has an important application in high technology equipment. In this study, the composite lubrication structure was prepared on the titanium alloy surface by combining the surface texture, thermal oxidation layer, and polytetrafluoroethylene(PTFE)-based lubricating coating. The effect of texture parameters and thermal oxidation layer on the fretting wear behavior of the composite lubrication structure was evaluated under a load of 50 N. The results showed that the PTFE-based lubricating coating on the textured surface showed excellent friction-reduction and anti-wear effect compared with the coating on the single smooth surface and thermal oxidation surface. The introduction of a thermal oxidation layer on the textured surface further improved the fretting wear life of lubrication coating. The friction coefficient and wear rate can be as low as 0.242 and 2.3 × 10−5 mm3·N−1m−1, respectively, under dry fretting contact conditions. Compared with the untextured surface, the longevity of the composite lubrication structure is extended by more than 90%.
