In this work, an in-situ XPS analysis test combined self-designed high precision fretting wear tester was carried out to study the fretting wear behavior and the resulting tribo-oxidation of thermal-oxidation film on Ti6Al4V titanium alloy under the varied working atmosphere. The fretting-induced tribo-oxidation under the air and vacuum ([Formula: see text] Pa) environment was analyzed and its response on the resulting fretting wear resistance and damage mechanism was discussed. Results show that the working environment plays a significant role in the formation of tribo-oxidation and then determining the fretting wear resistance. Thermal-oxidation film in the vacuum atmosphere shows a better fretting wear resistance than that in the air atmosphere for all fretting regimes, except for partial slip regime (PSR) where there is an equivalent fretting wear resistance. Compared with the substrate Ti6Al4V titanium alloy, the thermal-oxidation film in the vacuum atmosphere performs a good protection for titanium alloy, especially for slip regime (SR), but not applied for air atmosphere.

Effect Of Oxygen

A systematic experimental investigation was conducted to study the effect of oxygen environment of different pressure on the fretting wear behavior of Ti6Al4V titanium alloy. In order to well probe the real tribo-chemical state, in this work, an in-situ X-ray photoelectron spectroscopy (XPS) analysis test developed by a self-designed high precision fretting wear tester integrated with an XPS equipment was used. The tribo-oxidation formed at the different oxygen pressure and its effect on the fretting wear mechanism and the resulting fretting wear volume in the different fretting run regime were discussed. Results show that the oxygen environment of different pressure has significant influence on the wear resistance of titanium alloy depending on the fretting run regime. In the partial slip regime (PSR), different oxygen pressure plays a little influence on fretting wear behavior, while a significant influence for the mixed fretting regime (MFR) and slip regime (SR). The tribo-oxidations produced at the oxygen environment of different pressure for the different fretting run regimes are found to correlate well with the resulting fretting wear mechanism and the fretting wear resistance.

The fretting wear behavior of Cu-Al coating was investigated with and without fatigue load under the dry and wet (lubricated) contact conditions. The Cu-Al coating was plasma deposited on titanium alloy, Ti-6Al-4V. Wet contact condition reduced frictional force during cycling as evidenced by the lower tangential force. Wear analysis using the accumulated dissipated energy approach did not show any effect of contact surface condition. In other words, the relationship between the accumulated dissipated energy and wear volume showed a linear relationship, and it was independent of loading and contact surface conditions as well as of the fretting regime.

Rubbers are widely used in various fields as the important sealing materials, such as window seal, door seal, valve, pump seal, etc. The fretting wear behavior of rubbers has an important effect on their sealing performance. This paper presents an experimental study on the fretting wear behavior of rubbers against the steel ball under air conditions (room temperature at 20 ± 2 °C and humidity at 40%). Three kinds of rubbers, including EPDM (ethylene propylene diene monomer), FPM (fluororubber), and NBR (nitrile–butadiene rubber), are considered in experiments. The sphere-on-flat contact pattern is used as the contact model. The influences of the displacement amplitude, normal force, frequency, and rubber hardness on the fretting wear behavior are discussed in detail. White light profiler and scanning electron microscope (SEM) are used to analyze the wear mechanism of the rubber surface. The fretting wear performances of three rubbers are compared by considering the effect of the displacement amplitude, normal force, frequency, and rubber hardness. The results show that NBR has the most stable friction coefficient and the best wear resistance among the three rubbers.
