Niobium oxide films of different thicknesses can be produced on niobium electrodes by anodic polarization. The films produced by a galvanostatic method show different interference colours following the expected theoretical succession of colours. An electrical breakdown was observed which showed a significant dependence of the electrolyte concentration and current density. The relationship between the colour and the current density during the anodization of niobium samples are reported for… 

Studies on the electrochemical deposition of niobium oxide

Various strategies for the electrodeposition of niobium oxide from both non-aqueous and aqueous solution are explored. The methods used were based on the electrochemical manipulation of the pH which

Modification of niobium surfaces using plasma electrolytic oxidation in silicate solutions

Herein, a study of the plasma electrolytic oxidation (PEO) of niobium in an anodising bath composed of potassium silicate (K2SiO3) and potassium hydroxide (KOH) is reported. The effects of the K2SiO3

Influence of the forming electrolyte on the electrical properties of tantalum and niobium oxide films: an EIS comparative study

The electrochemical oxidation of Ta and Nb and the dielectric behaviour of the oxide films thus formed were investigated in the following electrolytes: H2SO4, HNO3, H3PO4 and NaOH. Characterization

The Mechanism of Electropolishing of Niobium in Hydrofluoric-Sulfuric Acid Electrolyte

Niobium surfaces are commonly electropolished in an effort to obtain optimal smoothness for high-field superconducting radio-frequency cavity applications. We report the use of controlled

Characterisation of anodic oxide films on zirconium formed in sulphuric acid: XPS and corrosion resistance investigations

Present work describes investigations of a two-step process consisting of galvanostatic anodising in a 1 M H2SO4 solution at 100 mA cm−2 up to the limiting voltages of 20, 60, 80, 100 and 120 V,

Porous structure obtained by anodizing niobium in NaOH

Porous structures can be produced as nanotubes, nanowires and membranes, and they can be used in gas sensors, magnetic and electronic devices, biotechnology, etc. These structures can be obtained by

A Model for the Formation of Niobium Structures by anodization

The fluoride use for anodizing electrolytes has been primarily responsible for the formation of nanoporous oxides at valve metals, except aluminum, since it causes a dissolution process. This study


During anodizing, the chemical attack of hydrofluoric acid (HF) electrolytes on niobium can promote the formation of oxides with porous structures. However, this chemical attack can also cause an



Kinetics of the formation of anodic oxide films on tantalum

Theories of the growth of anodic oxide films are discussed and their predictions concerning the current and temperature-dependence of the field examined. New measurements of the mean field in

A Theory of the Kinetics of Formation of Anode Films at High Fields

A theory is presented for the anodie oxidation of metals such a.s tantalum and Muminum. The theory of Mott and Cabrera has been extended to inelude effects of space charge on kinetics of the process
