The process of obtaining soluble compounds of niobium, for use in phosphating baths, and other treatment processes of metallic surfaces

摘要

Production of soluble compounds of niobium for use in processes for treatment of metal surfaces.The process of obtaining niobium compound soluble in phosphating baths or baths and processes of surface treatment, using the fusion 1200 198 C mixing part (g),Kg or TN) of niobium oxide and 5 parts (g, kg or TN) or hidru00e1xidos carbonates of alkali metals.The addition of compound of Nb in the formulation and bathing in the treatment of metallic surfaces, increasing the resistance to corrosion.
