“…It was reported that the binding energy of the atomic bonds for titanium and nitrogen elements has a significant influence on the phase and mechanical properties of TiN coatings [25]. Therefore, in this part, the XPS was employed to investigate the binding energies of the coatings prepared under different substrate temperatures, whose results are shown in Figure 5.…”

“…Being different from the above-mentioned deposition techniques, the coatings prepared via the magnetic filtered cathodic vacuum arc (FCVA) method have specific advantages, such as denser microstructure and stronger adhesion strength [20,21], which contribute to its excellent sand erosion resistance. Therefore, a lot of investigations about the use of the FCVA method for the deposition of TiN coatings have been made by our research group in the past several years [22][23][24][25][26]. For example, Zhang et al [24] studied the multilayer structure's sand erosion resistance of TiN coatings by the technique of FCVA with different TiN layers under the condition of the same total thickness.…”

“…Specifically, it has been demonstrated by Cao et al [22] that the gradient multilayered structure of TiN/Ti coatings could decrease the degree of deformation mismatch between the hard and soft layers during the impact process, leading to the higher toughness and excellent sand erosion resistance for coatings. Moreover, Zhang et al [25] revealed that the phase constituents and mechanical properties (the hardness and toughness) of TiN coatings can be optimized by adjusting the N 2 flow rate, which ultimately have a great influence on the anti-sand erosion performance of TiN coatings.…”

In this study, the anti-impact performance of the TiN coatings prepared under various substrate temperatures (35, 200, 400, and 600 °C) were evaluated using a cyclic impact tester under 104 cycles. Moreover, the microstructure and anti-impact performance-related mechanical properties (adhesion strength and nano-hardness) were investigated to reveal the underlying mechanism of how the substrate temperature affects the anti-impact performance of the coatings. The results showed that the substrate temperature has a great influence on the internal stress, nano-hardness, and adhesion strength as well as the anti-impact performance of TiN coatings, and the coatings prepared under 400 °C exhibit the best impact resistance. The small internal stress, strong adhesion strength as well as high hardness and H3/E2 value for the 400 °C prepared coatings are the main contributes.

Atomic structure, adhesion energy, and electronic properties of the bonding nature at CrN(200)/Ni(111) interfacial region are studied by first‐principle calculations based on density functional theory (DFT). A new method for building the heterostructure of CrN(200)/Ni(111) is proposed to solve the large lattice mismatching between CrN(200) and Ni(111) slab. Three models (OT, ST, and TL) with different interface distance are built up, and the total energy for each of them is calculated. Comparing with other stacking sequence, TL sites with 1.9‐Å spacing at the interfacial region shows the biggest value of adhesion energy after geometry relaxation. Furthermore, the contour of charge density, partial charge density of states, and Bader charge values of the TL sites with 1.9‐Å spacing are plotted out and calculated. Results indicate that covalency bonding between Ni and N ions and metallic bonding between Ni and Cr atoms are formed at the interfacial region.

“…Coating is an effective technology against erosion [11][12][13][14][15]. Coating with good strength and toughness on the surface of the material [16,17], combined with the use of a particle separation device, can negate the impact of the sand swallowed and promote service performance of the engine to the greatest extent. Though for many years, ceramic erosion-resistant coating has been used to improve the surface strength of materials in machinery industry, such as cutting and grinding tools [18][19][20][21], the aero-engine erosion is quite different from the conventional ones.…”

Sand erosion has always been a key threat to the performance and service life of aero-engines. The compressor, the key component installed at the front of the aero-engine, suffers the most from sand erosion, especially compressors serving in deserts. Ceramic hard coating is a traditional way to improve the hardness and wear resistance of cutting and grinding tools. It may also be used to improve the erosion resistance of aero- engine compressor. However, the mechanism of erosion damage is complicated, which may include wear, secondary erosion, anisotropic erosion, impact, and fatigue. Recent research discovered the major problems with ceramic hard coating on aero-engine compressors. In this paper, these following problems are discussed: the design of coating material and structure, the preparation method and technology, the effects of droplets and clusters of coating surface, microstructure and characteristics of interface. The review of the major problems and possible solutions discussed in this paper may contribute to the future research on erosion coating theoretically and practically.
