“…It is notable that surface microstructure is composed of some deposited planar areas (DPAs), which are the effects of discharges over the surface. These DPAs (in the form of volcano) were also observed for PEO coatings [31][32][33][34][35]. VON layers seem to have more rough surfaces than HON layers, confirming the data presented in the section 3.1.…”

“…3 The deconvoluted spectra of the Ti 2p, Nb 3d, Zr 3d, O 1s, and P 2p core excitations of the Ti-13Nb-13Zr alloy samples anodized at 100 and 140 V Table 2 Corrosion potential, polarization resistance, and the thickness of the anodic oxide layer on the Ti-13Nb-13Zr alloy after electropolishing [36] and after anodization at different potentials pores. The growth of an oxide layer via plasma electrolytic oxidation, local breakdown with a small spark, and the subsequent oxygen gas evolution resulted in the formation of this complicated structure [42,43]. The EIS is a very useful method for the determination of the corrosion resistance of the Ti-13Nb-13Zr alloy [30,[44][45][46][47][48].…”

This work presents the results of the investigations on the electropolishing and anodic oxidation of the Ti-13Nb-13Zr titanium alloy. Electropolishing was conducted in the solution containing ammonium fluoride and sulfuric acid, whereas the solution of phosphoric acid was used for anodic oxidation of the alloy. The influence of electropolishing and anodization process parameters on the texture (scanning electron microscopy (SEM)) and chemical composition (X-ray photoelectron spectroscopy (XPS)) of the surface layer was established. Electrochemical impedance spectroscopy in 5 % NaCl solution was used for the determination of the corrosion resistance of the alloy.

“…The same barrier layer was observed in all of the examined samples. The growth of an oxide layer via plasma electrolytic oxidation, local breakdown using a small spark, and the subsequent oxygen gas evolution resulted in the formation of this complicated structure [27,28]. The thicknesses of the obtained layers also depend on the electrolyte concentration.…”

a b s t r a c tInvestigations into the surface modification of a Ti-15Mo alloy via plasma electrolytic oxidation are reported. The oxidation process was conducted in a solution containing Ca(H 2 PO 2 ) 2 , H 3 PO 4 , or (HCOO) 2 Ca. Anodisation was performed at voltages in the range of 100-400 V. The morphology of the sample surface did not change during alloy oxidation at lower voltages. Higher voltages led to the incorporation of calcium and phosphorus or of calcium only into the formed oxide layer and to significant modification of the surface morphology. Based on the SEM and EDX analysis results, a set of samples was selected for further investigations. To study the surface of the Ti-Mo alloy after anodic oxidation, we used scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), thin-layer X-ray diffraction (TL-XRD), and X-ray photoelectron spectroscopy (XPS). The electrochemical characteristics of the modified alloy in Ringer's solution were determined. Anodisation results in a considerable increase in the corrosion resistance of the Ti-15Mo alloy.
