“…The coating exposed to hot-corrosion tests at 800 • C was characterized by high resistance against corrosive salt, even after 480 h, due to the formation of a thick and protective Al 2 O 3 scale. Barjesteh et al [62] proposed a mixed methodology consisting of Pt electroplating and low-temperature high-activity to deposit a PtAl coating on Rene 80. Although the successful methodology was presented, the improvement in the high-temperature lowcycle fatigue (HTLCF) was only about 5% as compared to the uncoated substrate material.…”

Thermal barrier coatings (TBCs) are widely used to improve the oxidation resistance and high-temperature performance of nickel-based superalloys operating in aggressive environments. Among the TBCs, aluminide coatings (ACs) are commonly utilized to protect the structural parts of jet engines against high-temperature oxidation and corrosion. They can be deposited by different techniques, including pack cementation (PC), slurry aluminizing or chemical vapor deposition (CVD). Although the mentioned deposition techniques have been known for years, the constant developments in materials sciences and processing stimulates progress in terms of ACs. Therefore, this review paper aims to summarize recent advances in the AC field that have been reported between 2019 and 2023. The review focuses on recent advances involving improved corrosion resistance in salty environments as well as against high temperatures ranging between 1000 °C and 1200 °C under both continuous isothermal high-temperature exposure for up to 1000 h and cyclic oxidation resulting from AC application. Additionally, the beneficial effects of enhanced mechanical properties, including hardness, fatigue performance and wear, are discussed.

“…where, h 0 is the overall penetration length of oxide intrusion, t is the exposure time of the metal surface to the environment, and K ox p and K γ p are the parabolic oxidation constant and the parabolic γ depleted layer constant, respectively, as expressed in Equations ( 9) and (10).…”

“…Meanwhile, the failure of material in a periodic-load environment at high temperatures can not only lead to damage by fatigue but also damage by oxidation mechanism, thus requiring a model that can reflect both of these damage mechanisms for a more precise prediction of the fatigue life of austenitic stainless steel [10]. The Coffin-Manson or Smith-Watson-Toper models have been used to predict the low-cycle fatigue (LCF) life but are limited in predicting accurate fatigue life by reflecting the damage mechanisms, such as fatigue and oxidation in a high-temperature region [11][12][13].…”

Austenitic stainless steel is a vital material in various industries, with excellent heat and corrosion resistance, and is widely used in high-temperature environments as a component for internal combustion engines of transportation vehicles or power plant piping. These components or structures are required to be durable against severe load conditions and oxidation damage in high-temperature environments during their service life. In this regard, in particular, oxidation damage and fatigue life are very important influencing factors, while existing studies have focused on materials and fracture behavior. In order to ensure the fatigue life of austenitic stainless steel, therefore, it is necessary to understand the characteristics of the fracture process with microstructural change including oxidation damage according to the temperature condition. In this work, low-cycle fatigue tests were performed at various temperatures to determine the oxidation damage together with the fatigue life of austenitic stainless steel containing niobium. The characteristics of oxidation damage were analyzed through microstructure observations including scanning electron microscope, energy-dispersive X-ray spectroscopy, and the X-ray diffraction patterns. In addition, a unified low-cycle fatigue life model coupled with the fracture mechanism-based lifetime and the Neu-Sehitoglu model for considering the influence of damage by oxidation was proposed. After the low-cycle fatigue tests at temperatures of 200–800 °C and strain amplitudes of 0.4% and 0.5%, the accuracy of the proposed model was verified by comparing the test results with the predicted fatigue life, and the validity by using the oxidation damage parameters for Mar-M247 was confirmed through sensitivity analysis of the parameters applied in the oxidation damage model. As a result, the average thickness of the oxide layer and the penetration length of the oxide intrusion were predicted with a mean error range of 14.7% and 13%, respectively, and the low-cycle fatigue life was predicted with a ±2 factor accuracy at the measurement temperatures under all experimental conditions.
