The present work compares the mechanical properties and corrosion resistance of WC-FeCrAl coatings manufactured using high-velocity oxygen fuel (HVOF) technology equipped with DJ2700 spraying gun and high-velocity air fuel (HVAF) equipment using M3 supersonic spraying gun. The results indicated that decarburization of carbide phase occurred in both. It was found out that the deposition velocity is an important factor influencing the density of the coating
and thus the amount of porosity. The HVAF sprayed WC-FeCrAl coating revealed the lowest degree of porosity, higher hardness and lower degree of decarburization, achieving the best properties in terms of electrochemical corrosion resistance compared to HVOF sprayed coating.
