“…In order to improve the bonding strength between the coating and the substrate, a transition layer is generally adopted. For instance, if the substrate is Ti alloy and the coating is TiN, Ti will generally be used as the material for the transition layer [7,24,72]. Interfaces of all kinds, such as those between coating and substrate, between different layers of the coating, and even inside the coating itself have great influence on the overall properties of the coating.…”

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.

“…First of all, the erosion in aero-engine is the combination of wear, secondary erosion, anisotropic erosion, impact, fatigue, and other damage modes [22][23][24]. The standards in strength and toughness of the coating are higher, and the protection of a single hard coating does not suffice.…”

“…Studies over the past years have provided new insights on the understanding using DΟE methodology. It has been applied for the investigation of the erosion resistance of coatings produced through thermal spray technologies such as high-velocity oxyfuel [25,30], plasma spray [31], arc ion plating [32], and filtered cathodic vacuum arc technique [33]. Nevertheless, few empirical studies have investigated the erosion performance of cold spray coatings through experimental design [34], which is a major innovative aspect of the present publication.…”

This study elucidates the performance of cold-sprayed tungsten carbide-nickel coating against solid particle impingement erosion using alumina (corundum) particles. After the coating fabrication, part of the specimens followed two different annealing heat treatment cycles with peak temperatures of 600 °C and 800 °C. The coatings were examined in terms of microstructure in the as-sprayed (AS) and the two heat-treated conditions (HT1, HT2). Subsequently, the erosion tests were carried out using design of experiments with two control factors and two replicate measurements in each case. The effect of the heat treatment on the mass loss of the coatings was investigated at the three levels (AS, HT1, HT2), as well as the impact angle of the erodents (30°, 60°, 90°). Finally, the response surface methodology (RSM) was applied to analyze and optimize the results, building the mathematical models that relate the significant variables and their interactions to the output response (mass loss) for each coating condition. The obtained results demonstrated that erosion minimization was achieved when the coating was heat treated at 600 °C and the angle was 90°.

“…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.…”

“…Moreover, extensive efforts have been devoted to improve the toughness of coatings, such as the optimization of structure and deposition parameters. 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.
