“…It has been reported that the thermal spray is a technique that produces a wide range of coatings for various applications (Herman and Sampath 1996). Erosion tests on coatings have been widely reported (Barbezat et al 1993;Takeda et al 1993;Wang 1993;Shipway and Hutchings 1995;Hearley et al 1999;Wang and Lee 2000;Mishra et al 2006;Sidhu et al 2007). The mechanisms of coating damage in such tests depend on the coating material and its thickness, the properties of the interface, the substrate material and the test conditions (Shipway and Hutchings 1995).…”

In the present investigation, stellite-6, Cr 3 C 2 -NiCr and WC-Co-Cr coatings were deposited by DGun on a hot rolled 21Cr-4Ni-N steel meant for fabrication of hydro turbine underwater parts. The coatings have been characterized for microstructure, porosity, microhardness and crystalline nature. The erosion experiments were carried out using an air jet erosion test rig at a velocity of 120 ms -1 and impingement angles of 30° and 90°. Silicon carbide particles of size ranging between 500 and 700 µm were used as erodent. Scanning electron microscopy (SEM) technique was used to analyse the nature and mechanism of erosion. Erosion behaviour is observed to be influenced largely by the nature and extent of porosity in the surface coatings.

“…With further increase in velocity, the hardness somewhat decreases in coating NA-3, possibly because of the incorporated in-flight solidified particles, leading to a less-defined lamellar structure and compromised splat contact. It should be pointed out that the measured hardness exceeds the values reported for conventional plasma (APS)-sprayed Al 2 O 3 -40% ZrO 2 coatings (Ref 37,38) and approaches those of APS-sprayed alumina, at similar macroscopic porosity. The SF-3 coating shows a lower hardness value, which is likely due to the presence of the weak amorphous phase.…”

“…Thermal sprayed carbide coatings, both WC-Co and Cr 3 C 2 -NiCr cermets, are extensively used for wear-and corrosion-resistant applications (Ref [1][2][3][4][5][6][7][8][9][10]. Coatings of the WC-Co system generally have a high hardness and wear resistance ( Ref 8,11).…”

Two 75%Cr 3 C 2 -25%NiCr feedstock powders with the same size distribution but different production process were characterized and found quite different in terms of morphology and phase composition. The powders were sprayed in a HVOF Diamond Jet (Sulzer Metco DJ-2600) torch with five different values of the oxygen-to-hydrogen ratio in order to assess the influence of this parameter on the microstructure and properties of the coatings. The results show that the closed and dense microstructure of one powder (Woka 7302) results in coatings with lower amount of decarburization, less oxide formation and higher toughness compared to coatings from the other powder (Praxair 1375). It was found that the O 2 / H 2 ratio impacts mainly on the YoungÕs modulus, which almost doubled by changing the ratio from 0.40 to 0.50, and on toughness, but does not notably affect the Vickers hardness.
