There are very few attempts to explore the erosion-wear behaviour of the Cr 3 C 2 -NiCr coating deposited on the nickel-based superalloy employed to resist the solid particle erosion damages for flue gas turbine blade. This work focuses on the erosion mechanism of Cr 3 C 2 -NiCr coating under service conditions. A 75 wt% Cr 3 C 2 -25 wt% NiCr composite coating was prepared on Ni-based superalloy substrate material using high-velocity oxygen-fuel spraying technique. The coating surface has been characterized. The erosion behaviour and the effects of air pressure, impingement angle, erosion temperature and particle size on the erosion resistance of coating were studied. The results indicate that the volume erosion rate of the specimen increases gradually with the increase in air pressure. The volume wear rates of coating material increase with the decrease in coating thickness. Coating shows better erosion resistance at 90°impact angle as compared to 30°impact angle. The maximum volume erosion rate occurs at impact angle of 60°. So, the combined mode of erosion mechanism (i.e. ductile and brittle) is observed in the Cr 3 C 2 -NiCr coating on nickel-based superalloy. The erosion-wear resistance of the materials can be improved at high temperatures. With the increase in the particle size, the volume erosion rates of the coating material increase. Erosion particle size and shape are the key factors that influence the erosion-wear behaviour.

“…At a 30° impact angle, the eroded surfaces reveal the SiC coatings are damaged slightly as compared to that of 90°, and the CS‐3 specimen show partial coating delamination yet. The presence of grooves and lips indicated the coating material removal by the microcutting and microploughing action (Figure E‐H) . So, the combined mode of erosion mechanism can be observed in the SiC coating.…”

To improve the erosion resistant of carbon‐carbon composites, an SiC coating was synthesized on carbon‐carbon composites by the in situ reaction method. They are firstly coated with carbon layer by slurry, and then SiC coatings are obtained by chemical vapor reaction. The effects of precoated carbon layer on the microstructure and anti‐erosion properties of SiC‐coated C‐C composites were studied and characterized. The thickness of the SiC coating increased with the increase in the precoated carbon layer thickness. The different thickness of carbon layer affects hardness of the SiC coatings, resulting in diverse erosion resistance of the coatings. The SiC coating prepared with moderate thickness of precoated carbon layer exhibits the best erosion resistance, and show better resistance at an impact angle of 30° than 90°. The eroded surface revealed that coating cracking and brittle fracture, fiber‐matrix debonding, fiber breakage, and material removal, and the additional microcutting and microploughing at oblique impact angle are the major erosion mechanism of SiC coating for C/C composites.

“…Erosion areas formed as elliptical shapes for 30° and 60° (Figure 8a), and as round shapes for 90° (Figure 8b). The elliptical shape was formed due to a higher flow divergence of the abrasive particles where the corners of hitting were 30° and 60° [45]. It is known that the removal of material from the surface occurs due to plastic deformation for small angles (less than 30°), and due to the formation of microdefects and subsequent ductile fractures for bigger angles (90°) [46].…”

Abstract:In this work, dense zircon-based ceramic coatings were obtained from inexpensive zircon powder on a steel substrate by using a new multi-chamber gas-dynamic accelerator. The microstructure and phase composition of the coating were characterized by scanning electron microscopy, optical microscopy, and X-ray diffraction. The mechanical properties of the coatings were evaluated using microindentation, wear tests and bonding strength tests. The results showed that the obtained zircon-based ceramic coatings were continuous without cracks and bonded well with substrate without a sublayer. The zircon-based ceramic coatings consisted of c-ZrO 2 (major phase), m-ZrO 2 and SiO 2 . The zircon-based ceramic coatings had a porosity of 0.1%, hardness of 526 ± 65 HV 0.2 , and a fracture toughness of 2.5 ± 0.6 (MPa·m 1/2 ). The coatings showed the low specific wear rate and average erosion rate. The failure mode occurring in the tested coatings was cohesive.
