“…Temperature and load promote the formation of GND and facilitate crack nucleation and propagation. Yang et al [33] improved the fretting fatigue life of TC11 titanium alloy by laser shock peening, and suggested that the fretting fatigue cracks were mainly nucleated in β phase. Zhang et al [34] investigated the effect of laser quenching on the fretting fatigue properties of TC11 titanium alloy.…”

“…The variation in the elastic modulus of the hardened layer was also taken into consideration. Yang et al [26] looked at how TC11's fretting fatigue properties were affected by laser impact strengthening. The findings of the experiment demonstrated that the specimens' fretting fatigue life was greatly increased by the laser surface treatment, with the highest improvement occurring at 4.8 GW/cm 2 .…”

In turbine tenon joint structures, fretting fatigue is common and can have detrimental effects on the components. To increase the fretting fatigue life, the design of tenon joint structures must be optimized. A parametric model of the three-tooth mortise and tenon joint structure is developed in this research. Sensitivity analysis yields the primary characteristic parameters, which are then employed as design variables. The objective function is the life of fretting fatigue. An aero-engine turbine three-tooth mortise and tenon joint structure was optimized against fretting fatigue using a Multi-Island Genetic Algorithm (MIGA), which was then experimentally verified. The optimization was based on the multidisciplinary optimization platform ISIGHT to write batch files integrating ANSYS and MATLAB. According to the findings, the three-tooth mortise and tenon joint structure’s fretting fatigue life can be increased by 51.3% by applying the MIGA. The contact pressure was reduced by 0.54% and the maximum slip amplitude has been reduced by 13%. The approach of optimization’s efficacy was confirmed.

“…Such textured polymer surfaces decorated with Ag NPs can be prospective antimicrobial coatings. Another example of laser-induced physical phenomena is laser shock peening, demonstrating significantly improving the fretting fatigue life of TC11 titanium alloy [ 14 ]. In the article by Piotr Kupracz et al [ 15 ] laser re-solidification was demonstrated as an approach for the modulation of morphology and structure of metal-decorated TiO 2 nanotubes to obtain visible light harvesting.…”
