“…This sticking clearly shows that the accumulation of plasticity has not yet formed the wear debris so the wear width, wear area and the hardness are still low as compared to high frequency 2.5 Hz. At high frequency, the plasticity accumulation completely turns into wear debris therefore less sticking formed especially at the end left and right of the wear track [3].…”

“…High performance of aero engine components experienced material wear losses resulting not only reduction to its performance but in some cases a complete failure of the components. Currently there is a limitation on life prediction of aero engine components due to inability to accurately predict the wear behavior for the components due to plasticity type deformation occurring on the contact pair [3].…”

Reciprocating sliding wear test of uncoated titanium alloy, Ti-6Al-4V is investigated using pin-on-flat arrangement under variables of reciprocal frequency set up (1, 2 and 2.5 Hz) for contact pin Ø6.5 mm. Frictional force resulted 60 -80 N tangential force in range and the graph pattern for COF resulted running-in condition at earlier second and highest peak experienced in value 0.45-0.48 in range. The micrography shows more sticking at the end of the wear track and significant at parameter 1 Hz frequency. The profilometry shows the result of wear width and wear area where the wear width is increasing with the increasing of frequency set up while wear area decreasing with the increasing of frequency. The hardness shows high value for 2.5 Hz. The cyclic plasticity presence is examined using Scanning Electron Microscope (SEM). The black spot present at the end of wear track are identified as an accumulation of ploughing during sliding and approved by the hardness result where the accumulation part experienced highest value 962 HV. This value proved that plastic deformation is formed during the sliding with the adhesive and abrasive mechanism.

“…The friction coefficient is depicted as a function of the number of cycles with logarithmic coordinates as shown in Figure 8, calculated by using the average amplitude Ti of a T-θ curve of each fretting cycle [42,43]. Generally, there are three typical stages that occur in the fretting running progress [44][45][46]. In the initial stage (stage I), the friction coefficients are relatively small, which could be due to two reasons: first, because of the protection and lubrication of fresh films on contacting surfaces; and second, because of the relative high roughness at very beginning of contact that causes a higher contact pressure, resulting in low friction [47,48].…”

In this study, efforts were made to oxidize the Ti3SiC2 coating surface to improve its wear resistance by producing oxide layers and healing microcracks that initiated from the thermal sprayed process. Tribological behaviors of the thermal oxidation-treated Ti3SiC2 coatings subjected to various temperatures (200, 300, and 400 °C) and durations (1, 3, and 5 h) were investigated comparatively by fretting wear. The results showed that the thickness of the oxide layer and the average content of element O on the surface were gradually increased with increasing temperature. Lower friction coefficients were observed in coatings at 200–400 °C for 1 h. Better performance of crack-healing features was demonstrated at 400 °C, whereas fresh microcracks were formed under the fretting condition due to the fragility of oxides at the same time. The tribological behavior of thermal oxidation-treated Ti3SiC2 coatings was mainly controlled by delamination and abrasive wear. The volume losses induced by wear scars decreased with the increase in oxidation time under the oxidation treatment at 200 °C and increased with increasing oxidation time under the oxidation temperatures of 300 and 400 °C.

“…Tobi et al. 15 studied the effect of plastic deformation on the fretting wear of Ti-6Al-4V alloy in the gross slip regime at the frequency of 20 Hz. It was found that under high load conditions, more plastic deformation occurred in the early fretting cycles, resulting in high wear rate.…”

Fretting wear between titanium alloy components in aero engine is prevailing in the blade dovetail, the blade crown, and the damping shoulders. In this study, the fretting wear behavior of Ti-6Al-4V alloy was investigated by changing the load and displacement under a high frequency (100 Hz). To simulate the actual working conditions in aero engines, both the ball and flat samples were Ti-6Al-4V alloy. It was found that as the load increased, or as the applied displacement decreased, the fretting regime changed from gross slip regime to partial slip regime. The coefficient of friction/traction at steady stage decreased as load increased. Wear scar morphologies varied with fretting running conditions. In gross slip regime, the central area was higher than the rest region of the wear scar. In the mixed slip regime, large material accumulation could be found at both ends of the reciprocating motion. In partial slip regime, a nearly original fretting sample surface was observed in the central area and wear occurred in the edge area. Furthermore, considering the wear of the paired samples, a method based on the fretting wear scar diameter was proposed to evaluate the fretting running conditions.
