“…These alloys have found applications in aircraft wings, space rocket oxygen tanks, and plane floor beams [ [2] , [3] , [4] ]. Binary Al–Li alloys exhibit a 6 %–8 % increase in elastic modulus while reducing density by 3 % for every 1 % addition of lithium [ 5 , 6 ]. To further enhance the alloy properties, the industrial Al–Li alloys are typically alloyed with the addition of several elements.…”

“…Aluminum alloy is widely used in ships, railways, transportation, aerospace, and other fields because of its high specific strength, strong corrosion resistance, and light weight [1,2]. Most failures of aluminum alloys occur on the surface in service [3,4]. Enhancing the comprehensive protection ability of aluminum alloy surfaces through surface nanocrystallization can significantly improve the service performance and life of the material [5][6][7].…”

Burnishing experiments with different burnishing parameters were performed on a computer numerical control milling machine to characterize the surface roughness of an aluminum alloy during burnishing. The chaos theory was employed to investigate the nonlinear features of the burnishing system. The experimental results show that the power spectrum is broadband and continuous, and the Lyapunov exponent λ is positive, proving that burnishing has chaotic characteristics. The chaotic characteristic parameter, the correlation dimension D, is sensitive to the time behavior of the system and is used to establish the corresponding relationship with the surface roughness. The correlation dimension was the largest, when the surface roughness was the smallest. Furthermore, when the correlation dimension curve decreases, the roughness curve increases. The correlation dimension and surface roughness exhibit opposite variation trends. The higher the correlation dimension, the lower the surface roughness. The surface roughness of the aluminum alloy can be characterized online by calculating the correlation dimension during burnishing.

Micro-arc oxidation (MAO) is a surface treatment technology that enhances the surface properties of valves by creating a ceramic oxide layer on the metal surface. The goal of this study is to investigate the influence of current density on the properties of aluminum coatings during preparation and to improve the tribological properties of MAO/PTFE self-lubricating films on the coating surface. The characterization of the coating was performed using X-ray photoelectron spectroscopy, X-ray diffraction, Raman spectra, and energy dispersive spectroscopy. The roughness, hardness, and elastic modulus of the coatings were tested using atomic force microscopy and nanoindentation. Tribological experiments were conducted to evaluate the tribological properties of the coatings.The experimental results show that the friction coefficient (COF), roughness, hardness, and elastic modulus of the MAO coating increase with the increase of current density. Additionally, the friction coefficient of the MAO composite coating significantly decreases after the addition of polytetrafluoroethylene (PTFE), improving the service life and application range of the metal coating.These findings are expected to promote the development of valve metal in various application fields.
