“…Góral et al [65] proposed a new concept of thermal barrier coating for MAR M247 with a Pt + Pd/Zr/Hfmodified aluminide bond coat and a ceramic layer formed by the PS-PVD method, which was found to be an attractive alternative to conventional coatings produced using the expensive electron beam physical vapor deposition (EB-PVD) method. Shademani et al [66] reported positive effects of rejuvenation heat treatment performed before pack cementation of ZHS32. The deposited β-NiAl coating was characterized by improved nanohardness, microhardness and elastic modulus as compared to the non-heat-treated substrate.…”

“…Such trends enforce the need to enhance the durability of coatings as well. Therefore, rare earth elements, including zirconium [18][19][20], hafnium [21,60,66], palladium [46,66], rhenium [47,52,69] and platinum [49,51,52,63,66,[69][70][71], are frequently added to significantly extend the service temperature of nickel-based superalloys up to 1300 • C. One can conclude that their addition is extremely beneficial as not only the operating temperature increase but also the material stability of the coating is improved.…”

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.
