“…However, with extended service life, the fretting corrosion behavior between steam generator tubes and their support plates, caused by the combined action of flow-induced vibration and medium erosion, will cause significant damage to their outer surface (Cheng and Zuo, 2018). According to the statistics of service status statistics, the fretting corrosion in steam generator tubes is highly prevalent, unavoidable and has become the primary damage pattern in steam generator tubes (Xing, 2018).…”

Purpose The purpose of this paper is to study the effect of surface salt spray duration on the fretting wear and electrochemical corrosion behaviors of Inconel 690 alloy. Design/methodology/approach A high-temperature steam generator was applied to salt spray test samples, a fretting wear rig was used to realize the damage behavior tests, an electrochemical workstation was applied to analysis the changes of each sample’s corrosion dynamic response before and after fretting wear. Findings The thickness of the oxide film that formed on sample surface was increased with the salt spray duration, and somewhat it could act as lubrication during the fretting wear process; however, the corrosive chloride would accelerate the fretting mechanical damage behavior. Originality/value In a salt steam spray condition, the fretting tribo-corrosion behaviors of Inconel 690 alloy surface was studied.

“…Furthermore, the oxidized debris will isolate the direct contact of the contact surface and cause serious underground damage. Xin et al [18][19] investigated the influence of frequency on the fretting corrosion behavior of the type 304 stainless steel and its mechanism under high temperature and high pressure water. Their results showed that the main sources of wear are delamination wear, material transfer wear, and oxidative wear.…”

The multi-field coupling mechanism of a continuously variable transmission (CVT) system has a greater impact on its overall friction loss. The friction loss of steel rings represents the internal loss of the metal belt occurring between the steel ring group and friction plate, and it is the main reason for the loss of CVT energy. This study is based on the dissipative wear model of the CVT steel ring friction pair, and it innovatively establishes a steel ring wear depth model that relates the wear depth to the macro- and micro-factors. Here, a mixed lubrication model between the friction pairs of steel rings is constructed, and the change law of oil film thickness, pressure, and temperature between the contacting bodies is obtained. On the basis of the wear depth model of the steel ring, the results of the wear depth of the steel ring are obtained via simulation using torque, speed, fretting frequency, and other operating parameters. The surface wear of the steel ring at different fretting frequencies is observed via SEM, and the simulation and test results are compared. Subsequently, the obtained results of the wear depth and oil film thickness tests are used to determine the safety margin of the application efficiency of the steel ring friction pair in the CVT working range via the interpolation processing method. According to the simulation results, the overall performance area of the safety margin of the application efficiency of the steel ring friction pair is between −1 and 1. When the torque is greater than 130 N•m, the safety margin value decreases below 0, the safety failure probability of the steel ring increases significantly, and the safety margin decreases gradually. This research can provide new insights into solving the reliability and service life of CVTs.

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.
