Niobium and its alloys have been used for several industrial applications including high strength low alloy steels (HSLA) in the automotive and aerospace industries, mainly because of being highly corrosion resistant in different media. Niobium pentoxide is an excellent option to reduce costs in repairing damages caused by corrosion, protection of industrial equipment or systems for being chemically inert to corrosive agents that cause severe corrosion and are normally present in refineries and other industrial environments. Whatever the application, mechanical properties of coatings define their effective durability and performance, mainly for tribocorrosion applications. In this work, these properties are studied and correlated for Nb2O5 coatings applied by Flame Spray onto steels. Salt Spray corrosion (ASTM B117), abrasive wear resistance (ASTM G65-16) and scanning electron microscopy (SEM) microstructural analysis allowed the evaluation of the coatings.
