“…The sliding velocity was 0.2 m/s along a diameter of 10 mm circular path with total sliding distance of 3.6 × 10 2 m, which was proved to be sufficient to attain a steady-state condition [18][19][20][21]. The friction coefficient was recorded by the tester automatically, and the mean friction coefficient was calculated based on the whole data, which was recorded during the sliding wear tests.…”

Abstract:The high temperature oxidation and wear behaviors of Ti-35V-15Cr-0.3Si-0.1C fireproof titanium alloy were examined at 873 and 1073 K. The oxidation weight gain after oxidation at 1073 K for 100 h was significantly larger than that at 873 K. Based on the analyses of the oxidation reaction index and oxide layer, the oxidation process at 1073 K was mainly controlled by oxidation reaction at the interface between the substrate and oxide layer. Dry sliding wear tests were performed on a pin-on-disk tester in air conditions. The friction coefficient was smaller at 1073 K than that at 873 K, while the volume wear rate at 1073 K was larger due to formation of amount of oxides on the worn surface. When the wearing temperature increased from 873 to 1073 K, the wear mechanism underwent a transition from a combination of abrasive wear and oxidative wear to only oxidative wear.

“…In many works, the role of tribo layer is the main consideration [1][2][3][4]. Mao et al [1] concluded that mechanically mixed layer (or tribo layer) role depends on whether more oxides appeared or not. In many cases, protective function due to their high hardness is expected.…”

Friction tests have been carried out for a Ti6Al4V tribopair by subjecting specimens to a normal pressure of 110 MPa at siding velocity close to 40 m/s to reproduce exceptional cases (bird ingestion or blade off) of contact between the blades root and the rotor slot in aircraft engines. Using friction coefficients experimentally measured, thermo-mechanical FE simulations have been performed. The first millimeters of sliding were investigated to clearly identify adhesive wear activation. Stress, temperature and plastic shear strain evolutions are used to evaluate a damage criterion. It was found that such extreme conditions lead to third body creation after only few millimeters of sliding.

“…However, many investigations have shown that the failure of performance is because of wear and friction [8]. Hence, to improve their application performance Ti-6Al-4V will be used in this study.…”

Abstract. Sliding contact will experience wear in majority of mechanical components during their service life where it reduces the performance of the components. The capability to predict the evolution of reciprocating wear scars, such as the scar's width and depth, would be a valuable tool when designing mechanical components. Wear scar mechanism behaviour is characterised during stabilized cycle reciprocating sliding wear test of Ti-6Al-4V investigated using pin-on-flat arrangement under variable duration of sliding. The test samples were analyzed using profilometer test, optical microscopy test, Scanning Electron Microscopy (SEM) test, Energy Depressive X-ray (EDX) test and Vickers Hardness (HV) test. Stabilised high number of cycles shows low wear rate and initiation period of low cycles produced higher wear rate.
