“…1 unidirectional; 2 reciprocating; and 3 multi-mode combination motion. Guo et al (2020aGuo et al ( , 2020b, 2020c) studied the effects of impact angles, excitation forces, clearances, support forms and other factors on the impact-sliding fretting wear and established an energy-based wear model, which is more accurate than the traditional Archard model. However, these studies did not consider the synergism of wear and corrosion.…”

Purpose The purpose of this paper is to investigate the effect of NaCl solution with different concentrations on impact-sliding fretting corrosion behavior of Inconel 690TT steam generator heat transfer tubes. Design/methodology/approach The optical 3D profiler was used to measure the wear profile and calculated the wear volume. Corrosion behavior was studied using open circuit potential monitoring and potentiodynamic polarization testing. The morphologies and elemental distributions of wear scars were analyzed using scanning electron microscopy and energy-dispersive spectroscopy. The synergism of wear and corrosion was analyzed according to the ASTM G119 standard. Findings The corrosion tendency reflected by OCP and the corrosion current calculated by Tafel both increased with the increase of NaCl concentration. The total volume loss of the material increased with concentration, and it was known from the synergism that the volume loss caused by corrosion-enhanced wear accounted for the largest proportion, while the wear-enhanced corrosion also made a greater contribution to volume loss than tangential fretting corrosion. Through the analysis of the material morphologies and synergism of wear and corrosion, the damage mechanism was elucidated. Originality/value The research findings can provide reference for impact-sliding fretting corrosion behavior of Inconel 690TT heat transfer tubes in NaCl solution with different concentrations.

“…They found that the wear degree at 25 °C is less than that at 290 °C, and the wear rate increase with the applied impact load's augmentation. Guo et al [8,9] conducted impact wear test studies to predict the dynamic relationships between impact angle, impact energy loss, and wear degree. Yilmaz et al [10] systematically studied the effect of impact wear cycles on the wear degree and failure mechanism of 316L stainless steel.…”

As an important nuclear power material, Inconel 690 alloy always need to suffer various harsh impact wear behaviors during its service period. Therefore, how to further enhance its surface wear resistance and objectively reveal its fretting wear mechanism under various conditions have vital scientific values for improving its service performance. This study first applies specific ultrasonic surface rolling process (USRP) to treat the Inconel 690 alloy surface with two and four times separately. And then a controllable impact kinetic energy wear test rig is used to comparative investigate the impact wear behaviors of as-received and USRP treated samples at 25 ℃ and 300 ℃ temperature. Results indicate that USRP can effectively improve the near surface Nano-hardness, residual compressive stress and other mechanical properties of Inconel 690 alloy, thereby increasing its impact wear resistance. The impact wear mechanism at 25 ℃ is plastic deformation causes fatigue spalling, and some adhesion wear are found at the 300 ℃ wear condition.

Impact–sliding caused by random vibrations between tubes and supports can affect the operation of heat exchangers. In addition, a corrosive environment can cause damage, accelerating the synergism of corrosion and wear. Therefore, the focus of this work was the impact–sliding fretting tribocorrosion behavior of 316L heat exchanger tubes at different halide concentrations. A device system incorporating the in situ electrochemical measurements of impact–sliding fretting corrosion wear was constructed, and experiments on 316L heat exchanger tubes in sodium chloride (NaCl) solution with different concentrations (0.0, 0.1, 0.5, 1.0, 3.5, and 5.0 wt%) were carried out. The synergism between wear and corrosion was also calculated and analyzed. The wear and damage mechanisms were elucidated by correlating the corrosion–wear synergism, morphologies, and material loss rates. The results indicated that the stable wear stage occurred at approximately 9–12 h, after which the corrosion current increased with the expansion of the wear area. As the halide concentration increased, the scale of damage on the wear scars gradually decreased, changing from being dominated by cracks, delaminations, and grooves to being dominated by scratches, microgrooves, and holes. There was an obvious positive synergism between wear and corrosion. The material loss was dominated by pure mechanical wear and wear enhanced by corrosion, but corrosion enhanced by wear contributed more than tangential sliding fretting corrosion. The total mass loss increased gradually in the range of 0.0–0.5 wt% and decreased in the range of 0.5–5.0 wt%. Large-scale damage enhanced by corrosivity and small-scale damage reduced by lubricity dominated the material loss at low and high concentrations, respectively.
