“…The porosity values of as sprayed WC-Co and Cr 3 C 2 -NiCr coatings are within the range of porosity values observed for HVOF using propane fuel coating by Wang and Lee [12], Wang and Shui [13], Wang and Lee [14] and Wang [15]. Low value of porosity may be due to the high impact velocity of the coating particles, which cause high density and high cohesive strength of individual splats as suggested by Scrivani et al [3].…”

This paper presents the experimental investigations carried out to study the influence of addition of Tungsten Carbide (WC) on the scratch resistance and high-temperature corrosion behaviour of flame-sprayed EWAC 1001 coatings on the AISI H13 steel substrate. The improvement in properties was analysed by conducting various tests such as microstructural analysis, microhardness, and scratch tests. Moreover, high-temperature corrosion tests were carried out on the coated as well as uncoated AISI H13 steel by exposing the material to air oxidation at 700• C under cyclic conditions. The thermogravimetric technique was used to establish kinetics of corrosion, whereas XRD and SEM/EDAX techniques which were used to analyze the AISI H13 steel with EWAC 1001 coating containing WC showed better resistance to high-temperature corrosion as compared to that of uncoated AISI H13 steel. It is observed that the formation of Cr 2 O 3 , NiO, and NiCr 2 O 4 contributes to the enhancement of high temperature corrosion resistance of the coating. The formation of unprotective Fe 2 O 3 oxide leads to intense spalling and peeling of the scales in the uncoated material. The results presented in this paper would be beneficial for improving properties of tools used in the die-casting industry.

“…The porosity values of D-gun sprayed coatings are very much lower (<0.8%) than that of HVOF sprayed Cr 3 C 2 -NiCr coating as reported in the literature [24][25][26][27][28]. The residual fuel used in heat engines such as gas turbines, boilers, and refinery furnaces contains sodium, vanadium and sulphur as impurities.…”
