“…Lawen Jr et al 51 investigated and compared high temperature (290 ∘ C, 345 ∘ C, 425 ∘ C, and 815 ∘ C) wear behavior of cobalt, nickel-based superalloys along with iron-based stainless steel. These alloys were tested in different combinations and optimal wear resistance was calculated among the couple.…”

Superalloys are a group of engineering alloys designed to operate at elevated temperatures, and they find application in various engineering sectors where a high-temperature application is required such as nuclear power plants, steam turbines, and aircraft. There are three important classes of superalloys, that is, iron-based, cobalt-based, and nickel-based superalloys. Among them, nickel-based superalloys find great application at both low and high temperatures due to their higher mechanical strength, good fatigue life, excellent wear, and corrosive resistance. This review article aims to review the tribological studies of the nickel-based Inconel superalloys. The article deals with the systematic studies of wear behavior, wear mechanism, and nanostructured glaze layer formation over the wear surfaces. The effect of load and temperatures influencing the wear rate and wear mechanisms of nickel-based superalloys are also discussed in detail. Along with that, the focus of this review article is to discuss the advancement in the tribological studies of the Inconel-718 superalloy. The development in the Inconel-718 alloys (surface alloying, laser shot peening, composites, microstructure engineering, etc.) to improve wear resistance is also discussed in a systematic manner. This article is expected to assist the researchers in identifying the trend and research gaps so that they can contribute to further tribological developments of nickel-based superalloys.

“…During the friction process of nickel-based superalloy at high temperature, it has been found that a thin and physically homogeneous oxide layer was formed on the component surface [17][18][19][20]. The formed oxide layer was also known as the glaze-layer, which was reported to contribute to the low coe cient of friction (COF) and wear rate for NBSC superalloys at high temperature [21,22]. A widely recognized speculation was that the glaze-layer was formed by compacting and sintering the wear particles produced during sliding process with the presence of heat [18, 23,24].…”

The tribological behavior of a nickel-based single crystal (NBSC) superalloy treated by shot-peening has been investigated. Friction tests under three normal loads and three temperatures were carried out based on the ball-on-disc con guration. The results showed that coe cient of friction (COF) and wear rate of the shot-peened superalloy at room temperature were nearly 2 times and 4 times that at 600 ℃, respectively. However, there were no signi cant difference in COF and wear rate between the shot-peened NBSC superalloy and the as-received NBSC superalloy, which was ascribed to the competing effects between the increased hardness and the increased roughness of NSBC superalloy after shot-peening. High temperature friction promoted the formation of a glaze-layer on the substrate, which was derived from the sintering and compacting of oxidized wear debris. The formed glaze-layer prevented the direct contact of the friction pair and contributed to the reduced COF and wear rate. The wear mechanism of the SP-NSBC superalloy at high temperature included oxidation, adhesion, and abrasion. With the decreasing normal load and increasing temperature, the adhesive wear weakened. This work provided insights into the effects of shot-peening treatment on the tribological properties of NBSC superalloy.
