“…The shear strength and compressive strength of the coating can be effectively improved by increasing the Al content in the coating, and the overall mechanical properties can be further improved [11]. Doping Si and Cr elements into the coating can effectively improve the mechanical, friction, and high temperature resistance properties of the coating [12,13]. Chang et al [14] prepared AlTiN and AlTiSiN coatings by an acathodic arc deposition system and compared them.…”

In order to further improve the mechanical and tribological properties of AlCrTiSiN coating, annealing treatment was carried out in this work. X-ray diffraction (XRD), scanning electron microscopy (SEM), nanoindentation, scratch tester, friction, and a wear tester were used to characterize and explore the effects of annealing temperature on the coating composition, phase component, surface and cross-sectional morphology, and mechanical properties as well as the friction and wear performance of the AlCrTiSiN coatings. The results indicated that after the vacuum annealing the content of amorphous phase decreased and the average size of nanocrystals increased in varying degrees. With the increase in annealing temperature the coating surface became smoother and the cross-section morphology changed little. The coating hardness first increased and then decreased. The adhesion between the coating and substrate decreased after annealing, but the wear resistance was improved. When the annealing temperature was 800 °C, the mechanical properties and wear resistance of the resulting coating were the best. In this case, the coating hardness was 27 GPa, the critical load was 61 N, the friction coefficient was 0.66, and the wear rate was 1.97 × 10−3 μm3/N·μm−1.

“…The outstanding deformation resistance of the Fe15Cr11Al0.5Y coating is completely consistent with its excellent bonding performance with the steel cladding tube (figure 3). Generally, the doping of the Si element will increase the brittleness of the coating [53], so Fe15Cr11Al2Si coating has relatively poor deformation resistance. The co-doping of Y and Si elements further amplifies the drawbacks of single-element doping, which in turn makes the coating have the worst mechanical properties.…”

The high-temperature lead-bismuth eutectic (LBE) corrosion resistance and ring compression performance of the Fe15Cr11Al2Si, Fe15Cr11Al0.5Y, and Fe15Cr11Al2Si0.5Y coatings were investigated. Even if the corrosion test temperature reaches 800 ℃, all these coatings can effectively protect the steel cladding tube. After the corrosion test temperature exceeded 660 ℃, an obvious Al-rich oxide layer was formed on the surface of the coating, and Al element enrichment occurred at the interface between the coating and the substrate. After the corrosion test at 800 ℃, holes appeared in the thick interface layer of the Fe15Cr11Al2Si0.5Y coating. The Fe15Cr11Al2Si coating cracked after the ring compression test with a deformation rate of 3%, and the coating peeled off after the deformation rate reached 5%. When the deformation rate reached 5%, there was still no cracking in the Fe15Cr11Al0.5Y coating. When the deformation rate reached 30%, the coating cracked, but the cracked coating was still tightly bonded with the substrate. The Fe15Cr11Al2Si0.5Y coating has the worst compression performance, even if the deformation rate is 1%, the coating still peels off obviously. The underlying mechanism for the evolution of corrosion resistance and compression performance was discussed.

In this work, the effect of 800 °C and 1100 °C post-heat treatment on the plasma spraying of Ti–Si–C–xMo (x = 1.0, 1.5) composite coatings was investigated. The composite coatings were composed of TiC, Ti3SiC2, Ti5Si3 and Mo5Si3 reacted phases. After heat treatment, the Ti3SiC2 and Mo5Si3 phases increased. The coating microhardness decreased by 16% and 18% for Ti–Si–C–1.0Mo and Ti–Si–C–1.5Mo coatings, respectively, after heat treatment at 1100 °C. Fracture toughness increased by 16% for the Ti–Si–C–1.5Mo coating after heat treatment at 1100 °C, which was mainly due to the heat treatment promoting Ti3SiC2 formation, healing micro-cracks, reducing the internal stress and making the microstructure dense. The coating friction coefficient before and after heat -treatment was between 0.4 and 0.6. After heat treatment, the wear amount of the coating was first reduced and then increased, and the minimum wear loss occurred after heat treatment at 800 °C. The wear mechanism was mixed abrasive wear, adhesive wear and tribo-oxidation wear.
