“…In the study [41], the tribological properties of α+β Ti (Ti6Al4V and Ti6Al7Nb) alloys were studied, and the results showed that the coefficient of friction is in the range from 0.3 to 0.6, depending on the sliding speed and load. Similarly, the authors of [42] have studied the friction coefficient of Ti6Al7Nb alloy, and the COF decreased from 0.58 to 0.42 with an increase in the sliding time and increased with the rise of the applied load.…”

In this study, we present the results of Young’s modulus and coefficient of friction (COF) of Ti–Ta surface alloys formed by electron-beam surface alloying by a scanning electron beam. Ta films were deposited on the top of Ti substrates, and the specimens were then electron-beam surface alloyed, where the beam power was varied from 750 to 1750 W. The structure of the samples was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). Young’s modulus was studied by a nanoindentation test. The coefficient of friction was studied by a micromechanical wear experiment. It was found that at 750 W, the Ta film remained undissolved on the top of the Ti, and no alloyed zone was observed. By an increase in the beam power to 1250 and 1750 W, a distinguished alloyed zone is formed, where it is much thicker in the case of 1750 W. The structure of the obtained surface alloys is in the form of double-phase α’and β. In both surface alloys formed by a beam power of 1250 and 1750 W, respectively, Young’s modulus decreases about two times due to different reasons: in the case of alloying by 1250 W, the observed drop is attributed to the larger amount of the β phase, while at 1750 W is it due to the weaker binding forces between the atoms. The results obtained for the COF show that the formation of the Ti–Ta surface alloy on the top of Ti substrate leads to a decrease in the coefficient of friction, where the effect is more pronounced in the case of the formation of Ti–Ta surface alloys by a beam power of 1250 W.

“…Figure 7 shows a schematic diagram of the lubrication mechanism of nanolubricant. The mechanism of nanolubricating liquid for copper-steel composite plate lubricant is that as the grinding time increases, the particle and crystallite size continually decrease (Mamoun et al, 2020(Mamoun et al, , 2023a(Mamoun et al, , 2023b and nano-AlN or Al 2 O 3 particles are dispersed in the lubricant to form a dense lubricating film on the surface of the copper plate, which can reduce the COF and friction and wear. Second, nano-AlN or Al 2 O 3 particles fill the defects on the surface of the copper plate, which effectively reduces the surface contact area and reduces the friction force and COF.…”

Purpose This paper aims to investigate the preparation of AlN and Al2O3, as well as the effect of nano-AlN and nano-Al2O3, on friction and wear properties of copper-steel clad plate immersed in the lubricants. Design/methodology/approach Nano-AlN or nano-Al2O3 (0.1, 0.2, 0.3, 0.4 and 0.5 Wt.%) functional fluids were prepared. Their tribological properties were tested by an MRS-10A four-ball friction tester and a ball-on-plate configuration, and scanning electron microscope observed the worn surface of the plate. Findings An increase in nano-AlN and Al2O3 content enhances the extreme pressure and anti-wear performance of the lubricant. The best performance is achieved at 0.5 Wt.% of nano-AlN and 0.3 Wt.% of nano-Al2O3 with PB of 834 N and 883 N, a coefficient of friction (COF) of approximately 0.07 and 0.06, respectively. Furthermore, the inclusion of nano-AlN and nano-Al2O3 particles in the lubricant enhances its extreme pressure performance and reduces wear, leading to decreased wear spot depth. The lubricating effect of the nano-Al2O3 lubricant on the surface of the copper-steel composite plate is slightly superior to that of the nano-AlN lubricant, with a COF reaching 0.07. Both lubricants effectively fill and lubricate the holes on the surface of the copper-steel composite plate. Originality/value AlN and Al2O3 as water-based lubricants have excellent lubrication performance and can reduce the COF. It can provide some reference for the practical application of nano-water-based lubricants.

Currently, Ti-6Al-4V alloy is one of the most used materials in biomedical devices, namely in orthopedic prothesis, thanks to its outstanding properties. However, its composition contains vanadium ions, considered toxic to the human body. Since the 1980s, there has been a growing effort to replace this alloy with less toxic alternatives. A promising candidate is the Ti-6Al-7Nb alloy. There are relatively few studies on the surface properties of this alloy, on the other hand, the knowledge of its tribological performance is of great importance for the use of this alloy in biomedical applications. Digital tribology has great potential in a quantitative inspection of wear in materials engineering. Methodologies of surface inspection, such as fractal description, can explain the relationship between microstructural, tribological parameters, and surface roughness. In this work, the inspection of the fractal behavior of worn surfaces of both Ti-6Al-4V and Ti-6Al-7Nb samples was carried out. Tribological tests were performed in a block-on-disk tribometer, using AISI 1045 steel as antagonist material, under different conditions. The fractal values were correlated to tribological parameters and the evolution of morphological aspects along the surface. Elevation maps of the sliding surfaces were built from pictures obtained from optical microscopy (OM). The “Extended depth from focus”, (EDF) reconstruction method, allowed the ordering of stacks of images to conduct a quantitative investigation of the behavior of surfaces.
