“…At high impingement angle (90°), the striking area decreased resulting in less surface deformation whereas for 60°impingement angle, the area of erodent impact increases which results in increased deformation and hence increased erosion wear. This observation is in line with the literature, where higher erosion wear is reported to occur at 60°impingement angle [16]. It is also observed that erosion rate of coated AA5083 sample is lower than that of coated AA1050 sample.…”

“…The slurry erosion performance of high-velocity oxyfuel sprayed WC-10Co-4Cr and Al 2 O 3 + 13TiO 2 coatings on CF8 M turbine steel was examined and, they stated that the high-velocity oxy-fuel sprayed WC-10Co-4Cr coating performed better than Al 2 O 3 + 13TiO 2 coating at increasing the slurry erosion resistance of CF8 M turbine steel [15]. The erosion performance of high-velocity oxy-fuel sprayed WC-10Co-4Cr coatings on cast and solution treated 23-8-N nitronic steel and reported that the coated cast steel exhibited lower erosion resistance as compared to coated solution treated 23-8-N nitronic steel [16]. In another study related to the erosion wear performance of high-velocity oxy-fuel sprayed WC-10Co-4Cr, Stellite 6 and 12 powder coatings on X20Cr13, 17Cr-4Ni pH steels and Ti6Al4 V titanium alloy.…”

TiAlN coatings were deposited on AA1050 and AA5083 aluminium alloys by high‐velocity oxy‐fuel (HVOF) spray process and evaluated for their mechanical and slurry erosion performance. In comparison to base alloys, the mechanical properties were found to enhance upon coating. The effect of working parameters namely impingement angle, impact velocity, erodent size and erodent feed rate on the slurry erosion wear rate has been investigated. The slurry erosion wear rate of the uncoated samples was found to decrease with an increase in the impingement angle whereas for coated samples the slurry erosion wear rate first increased, reached to a maximum value at 60° and then decreased with further increase in the impingement angle. For uncoated and coated samples the slurry erosion wear rate was found to increase with an increase in impact velocity, erodent size and erodent feed rate. Finally, the morphology of the eroded surfaces was analyzed using scanning electron microscopy and the possible erosion mechanisms have been studied.

“…In the case of plasma spraying, since the temperature of the plasma flame is very high, the WC is easily decomposed, even though the interior of the plasma flame is below the oxidizing atmosphere [2][3][4]. HVOF spraying, in which oxygen and fuel are combusted to accelerate feed stock powder towards the substrate building up the coating, is the most common process [5].…”

The aim of this research was to investigate microstructural and mechanical properties of the WC-Co-Cr coatings by high velocity oxygen fuel spraying. Woka 3653 (WC10Co4Cr) powder was used as coating material. This powder is widely used as a tribological coating material providing a combination of high toughness, high hardness, and good strength. The coatings were produced for the different high velocity oxygen fuel spraying parameters. The treated samples were characterized by using scanning electron microscopy/energy dispersive X-ray spectrometry and X-ray diffractometry. Microhardness measurements were executed to evaluate the mechanical properties of the coatings. Also the wear performance of the coatings was investigated. The scanning electron microscopy and energy dispersive X-ray spectrometry analyses were applied to worn surfaces. The results indicated that the coating shows slightly higher microhardness and better abrasive wear resistance than the conventional counterpart.
