“…The largest contact stress was generated in the subsurface layer. Serious cumulative damage 25 occurred in the interior of the material resulting in the plastic deformation. If defects existed in the deformation zone, then holes or microcracks were formed more easily in alternating normal load than no alternating load.…”

This study investigated the fretting wear behavior of the nuclear power material Inconel 690 alloy. An improved PLINT high-temperature fretting tester was used on an Inconel 690 tube against a 1Cr13 cylinder at different temperatures (25 C and 300 C) under alternating load conditions. The fretting-wear mechanism and the kinetic characteristic of Inconel 690 alloy were analyzed. Results showed that the fretting running behavior was closely related to the normal excitation frequency. In parallelogram shaped F t-D curves, the friction fluctuates periodically, and accordingly the fretting was running in the slip regime. The steady-state friction force at room temperature in air was higher than that at 300 C. Moreover, the damage behavior of the fretting for Inconel 690 alloy strongly depended on the normal load, displacement amplitude, temperature, and excitation frequency in atmospheric environment. A superposition effect of fretting wear behavior was discovered because of the combined effect of alternating normal and tangential forces; thus, delamination became more significant. Abrasive wear and delamination were the major mechanisms in Inconel 690 alloy at room temperature in ambient air. The dominant mechanisms at 300 C were the abrasive wear, oxidation wear, and delamination.

“…[25,26] Different alloys have been developed for this purpose and tested for their corrosion and creep strength under field conditions. [26] For higher temperature and pressure applications, nickel-based alloys [27][28][29][30][31][32] are proposed as candidate materials. These alloys are compatible with higher temperature applications and are known for their higher oxidation resistances.…”

Inconel 625 is a nickel‐based alloy with exceptional creep and corrosion resistance properties. It has emerged as a candidate material for operational and structural use in critical and supercritical power generation plants. Supercritical power plants work at high temperatures, pressure and in an erosive environment that makes metallic materials more vulnerable to corrosion fatigue. This study aimed to evaluate the fatigue crack growth rate (FCGR) at elevated temperatures (550–650°C) in a steam and supercritical water environment. All the experiments were performed at a water oxygen level of 8000 ppb. A cyclic stress of 1 Hz frequency and sine waveform was applied for the test. A 0.6 stress ratio was applied with a maximum stress intensity factor of 32 MPa√m. A direct current potential drop method was applied to detect the crack growth rate (CGR). For the given parameters, fractographic analysis validated the role of corrosion‐fatigue interaction as the primary source of variation in the FCGR. Results revealed that the CGR was enhanced with a rise in temperature under all test environments. The influencing mechanism of temperature on CGR was also discussed.

“…superior stress corrosion cracking resistance, and excellent mechanical characteristics at high temperature and in high pressure water. Although many detailed studies have been carried out on fretting fatigue [6][7], corrosion behavior [8][9] and stress corrosion cracking in simulated PWR primary water [10][11][12], they rarely revealed relevant information on fretting wear of Inconel 690 alloy in PWR secondary water. The fretting action possibly results in contact surfaces wear by detachment of particles, and contact fatigue by rapid crack nucleation and propagation, leading to premature catastrophic failures [13].…”

The aim of this paper is to assess the effect of water temperature (room temperature -RT, 60 ℃ and 90 ℃) on fretting wear behavior of 690 alloy tubes against 405 stainless steel plates, and compare it with fretting in dry condition. Due to the lubrication effect, the presence of a thin water film likely precluded the metal-metal contact, and resulted in less wear. During the fretting process, water also washed the wear particles away from the contact zone leading to a decrease of abrasive wear. Consequently, the wear scars showed "U" shape profile along the fretting direction in water, while "W" shape in air.
