“…However, the wear track of 2Hz is surrounded by an accumulation of loose debris, with pockets of debris trapped within the contact region. Additionally, some cracks and delamination occurs on the wear scar, so the wear mechanism is abrasive wear [21]. Meanwhile, the tribochemical reaction is easy to occur at the friction interface due to the high chemical reactivity of DU and long-time contact with air.…”

The Ti/TiN multi-layer film was prepared on the depleted uranium (DU) substrate by cathodic arc ion plating equipment. The character of multi-layer film was studied by SEM, XRD and AES, revealed that the surface was composed of small compact particle and the cross-section had a multi-layer structure. The fretting wear performance under different frequencies was performed by a MFT-6000 machine with a ball-on-plate configuration. The wear morphology was analyzed by white light interferometer, OM and SEM with an EDX. The result shows the Ti/TiN multi-layer film could greatly improve the fretting wear performance compared to the DU substrate. The fretting wear running and damaged behavior are strongly dependent on the film and test frequency. The fretting region of DU substrate and Ti/TiN multi-layer under low test frequency is gross slip. With the increase of test frequency, the fretting region of Ti/TiN multi-layer change from gross slip to mixed fretting, then to partial slip.

“…In acid solution, wire surface wear is similar to "pickling and polishing". Coupled roles of solution medium and SO 4 2lubricating film cause the good lubrication at the fretting contact surface, and thereby induce a smaller maximum tangential force and a larger relative slip [21,22]. In the case of deionized water, it presents the worse lubrication and no electrolyte ion effect as compared to the case of acid solution, which indicates a larger maximum tangential force and a smaller relative slip.…”

The wear rate and dissipation energy during tension–torsion cyclic loading of steel wires with fretting contact in different environmental media were explored in this study. Hysteresis loops of tangential force versus displacement amplitude (Ft-D) and torque versus torsion angle (T-θ), and their dissipation energies were obtained employing the self-made test rig. Morphologies of wear scars of steel wires were observed employing the white light interference surface morphology. The quantitative demonstration of the coefficient of cyclic wear of steel wire was carried out combining polynomial fitting, reconstruction of three-dimensional geometric model of wear scar and Archard’s equation. The results show that Ft-D curves reveal both decreases of the relative slip and dissipation energy in the order: corrosive media, deionized water and air. Increases of contact load and crossing angle caused overall decreases in the relative slip and dissipation energy, while the relative slip and dissipation energy both increased with increasing torsion angle. T-θ curves indicated the largest and smallest dissipation energies in cases of acid solution and deionized water, respectively. Increases of contact load, crossing angle and torsion angle caused increases in relative slip and dissipation energy due to cyclic torsional loading with fretting contact. The wear coefficient in cases of distinct environmental media decreased in this order: air, corrosive media and deionized water. Increases of the contact load, torsion angle and crossing angle all induced increases in the wear coefficient.

“…The erasure process of the imperfect flat surface resulted in the initial stage with the low and slowly increasing values of COFs. This stage is also called the run-in stage [9]. (2) Sharply increasing stage (50 < N < 200): as the removal of the adsorption products or oxide films after certain cycles, direct contact of the fretting pairs happens (metal-to-metal contact) and result in the stick phenomenon, hence the COFs increase sharply.…”

“…Therefore, for SG tubes, fretting corrosion is ineluctable and it can result in tube thinning or even leak of radioactive substances [5]. Plenty of researchers have focused on the fretting wear behavior of Alloy 690TT alloy between various materials [6][7][8][9][10]. It is doubtless that mechanical parameters, including displacement amplitude [11,12], normal force [13,14] and frequency [15,16] are crucial factors affecting the fretting wear process.…”

“…Some previous researchers have focused on the influence of temperature and made great contributions to reveal the underlying reasons. However, up to now, most of the researches were carried out in the water lower than 100 °C, at low frequency or with fairly large displacement, which may alter the result from the ones in actual operating conditions in NPPs [6,9]. Some researches performed in hightemperature high-pressure (HTHP) water are reported [14,24,25]; however, the test term during the fretting corrosion tests is a little short.…”

In pressurized water reactor, fretting corrosion has become the main reason for the failure of 690TT heat exchanger tubes. The effect of temperature on the fretting corrosion behavior between 690TT tube and 405 stainless steel (SS) bar has been studied during 10 6 fretting cycles. The overall average coefficient of friction (COF) values descends with an increase in test temperature, while the width of worn scar becomes wider. The severest fretting corrosion happens when the test temperature is at 100 °C. The wear mechanism differs at different test temperatures, from adhesive wear at room temperature to abrasive wear and delamination at 100 °C, to abrasive wear at 200 °C. Deformation slips, high residual strain concentration, and micro-cracks are found which are disadvantageous for the further service performance of the tubes.
