“…Finally, a coating is f on the face of the substrate. The process conditions, composition thickness [16], a oxidation characteristics of the SS coatings on Nb-based alloys are summarized in 1. It can be perceived that the thickness of SS coatings was between 150 and 300 μm the sintering temperature of 1200 to 1500 °C for 1-4 h in a vacuum or Ar atmosphe The typical surface and corresponding cross-sectional morphologies of SS coatings are shown in Figure 2.…”

Niobium (Nb)-based alloys have been extensively used in the aerospace field owing to their excellent high-temperature mechanical properties. However, the inferior oxidation resistance severely limits the application of Nb-based alloys in a high-temperature, oxygen-enriched environment. Related scholars have extensively studied the oxidation protection of niobium alloy and pointed out that surface coating technology is ideal for solving this problem. Based on the different preparation methods of Nb-based alloys’ surface coatings, this article summarizes the relevant research of domestic and foreign scholars in the past 30 years, including the slurry sintering method (SS), suspension plasma spraying method (SPS), and halide activated pack cementation method (HAPC), etc. The growth mechanism and micromorphology of the coatings access by different preparation methods are evaluated. In addition, the advantages and disadvantages of various coating oxidation characteristics and coating preparation approaches are summarized. Finally, the coating’s oxidation behavior and failure mechanism are summarized and analyzed, aiming to provide valuable research references in related fields.

“…In spite of efforts to develop modified aluminide coating, the silicate-based coatings have greater potential for protection at high-temperatures 5,21,22 . In this case, when modified with Fe and Cr, it is possible to obtain coatings with better oxidation resistance and the coated formed does not affect the strength at temperatures above 1100 °C 23 .…”

The coating formation by Fe-Cr-Si codeposition was done in a single step via Halide Activated Pack Cementation (HAPC) on Nb-Si alloy with the aim of improving the oxidation resistance. The activator salt and temperature selections for HAPC process were obtained by thermodynamic analysis. The isothermal oxidation test results for the coated alloy at 1200 °C for 62 h showed good oxidation resistance. The mass gain was 17.5 mg/cm 2. Furthermore, no cracks and spallation on the oxide layers were observed for the coated alloy after the oxidation test, being that the oxidative kinetics curve is in accordance with the parabolic rate law. On the other hand, total oxidation was observed for the uncoated alloy after 12 h at 1200 °C in the isothermal oxidation test. The mass gain was 49.27 mg/cm 2 and several cracks and spallation on the oxide layers led to a severe oxidation process.
