“…In order to analyze the mechanism of Mn participating on oxidation, the oxidation rate constant and free energy of several typical oxides were collected as shown in Figure 6 a,b. The oxidation rate constant of Al 2 O 3 oxide layer is more than 2.5 g 2 cm −4 s −1 lower than Cr 2 O 3 oxide layer and the free energy is nearly 300 kJ/mol lower than Cr 2 O 3 oxide layer, which indicates that the Al 2 O 3 oxide film will be formed more slowly as well as be denser and more stable [ 2 , 35 , 39 , 43 , 44 , 45 ]. Figure 6 c analyzed the mechanism of the effect of Mn addition on the oxide film of AFA steel.…”

“…Furthermore, the addition of Mn promotes Cr segregation and accelerates the formation of a large sized σ phase, which is the starting point of crack propagation and damages the mechanical properties of AFA steel [15,23,36,40]. However, the elongation of the 12Ni experimental steel decreased from 35% to 21% with the increase in Mn content at 650 • C. This is because the decrease in B2-NiAl phase and secondary NbC phase, which are effectively strengthened phases for AFA steel [17,[33][34][35][36], while the strengthening effect of the larger M 23 C 6 phase will be weakened at a high temperature. In conclusion, adding the Mn can slightly reduce the strength of the AFA steel at room temperature and high temperature, and increase the room temperature elongation, but will greatly reduce the high temperature elongation.…”

Al2O3-forming austenitic steel (AFA steel) is an important candidate material for advanced reactor core components due to its excellent corrosion resistance and high temperature strength. Al is a strong ferrite-forming element. Therefore, it is necessary to increase the Ni content to stabilize austenite. Ni is expensive and highly active, and so increasing the Ni content not only increases the costs but also damages the radiation resistance. Mn is a low-cost austenitic stable element. Its substitution for Ni will not only help to improve the irradiation resistance of austenitic steel, but also reduce the cost. In order to explore the feasibility of Mn-substituted Ni-stabilized austenite in AFA steel, this paper summarized the research progress of Mn-added AFA steels, whilst the research status of traditional Mn-added austenitic steels are also referred to and compared herein. The effect of the addition of Mn on the microstructure and properties of AFA steel was analyzed. The results show that Mn can promote the precipitation of the M23C6 phase and inhibit the precipitation of the B2-NiAl phase and secondary NbC phase. With the increase in Mn content, the strength of AFA steel at room temperature and high temperature decreased slightly, the room temperature elongation increased slightly, while the high temperature elongation and creep resistance decreased obviously. In addition, for austenitic steel free of Al, the addition of Mn will destroy the oxide layer of Cr2O3, which will decrease the oxidation resistance of the steel. But the preliminary study shows that Mn has little effect on the Al2O3 oxide layer. It is worth studying the effect of Mn-substituted Ni on the oxidation resistance of AFA steel. In summary, more efforts are necessary to investigate the optimal Mn content to balance the advantages and disadvantages of introducing Mn instead of Ni.

“…The integration of thermal spraying technology and SHS technology has gradually developed and formed reactive thermal spraying technology. In the process of reactive thermal spraying, since the ceramic hard phase is synthesized by in-situ reaction, the dependence on the heat source in the spraying process is greatly reduced, and at the same time, the coating structure with dispersed hard phase on the metal substrate is obtained [6][7].…”

Wear performance and behavior of as-sprayed TiB2-TiC0.3N0.7 matrix coating were investigated with different rotation speeds of counterpart and applied load. Analytical balance was used to weigh wear quantity. Scanning electron microscopy was used to observe surface morphology, abrasion scratch, and wear debris was researched through an energy dispersive spectrum. It is found the mass loss of matrix coating increases with the loading load increment at a low rotation speed of the counterpart. And wear loss decreases first and then increases with the increment of loading load at the high rotary speed of the counterpart. The wear mechanism of abrasive wear, adhesion wear, oxidation wear, and fatigue wear appear during the test of composite coatings at different rotation speeds of the counterpart and applied load.
