NIOBIUM-BASED COMPOSITIONS AND COATINGS, NIOBIUM OXIDES AND THEIR ALLOYS APPLIED BY THERMAL SPRAYING AND THEIR USE AS AN ANTICORROSIVE

摘要

"Compositions and coatings based on niobium, their oxides and alloys applied by thermal spraying and its use as an anti-corrosion.The innovation proposed describes the application of compositions and coatings based on niobium, their oxides and their alloys being possible associations with other oxides and alloys.By means of thermal spraying technique with the aim of corrosion protection in highly corrosive environments, especially those with high temperatures, the presence of gases such as,For example, H ~ 2 ~ s, so ~ 2 ~ ~ 2 ~ Co, as well as organic and inorganic acids, commonly found in industrial parks.
