Influence of the electrical parameters of the anodizing PEO process on wear and corrosion resistance of niobium

In this work, anodic coatings were obtained on niobium by plasma electrolytic oxidation (PEO). Surface topography variation depending on the electrical perturbation mode of the PEO process was evidenced. Coatings obtained at galvanostatic mode exhibited the formation of circular pores with no variat...
