Application-wise nanostructuring of anodic films on titanium: a review

Effect of etching on the composition and structure of anodic spark deposition films on titanium

“…Titanium anodizing is a consolidated technology that is used to produce the formation on the metal of an oxide film, always based on the titanium dioxide (TiO 2 ) formation but with different thickness, crystal structure, morphology and composition depending on process parameters [1,2]. This treatment is particularly spread in biomedical applications, where the favourable combination of mechanical properties, durability and biocompatibility of titanium and its alloys make them particularly suitable for dental and orthopaedic implants, as well as for ostheosynthesis devices [3,4].…”

Enhancement of pure titanium localized corrosion resistance by anodic oxidation

“…For this reason, treatments that act on the naturally formed passive layer are preferred. The easiest and cheapest treatment to tune oxide layer is anodic oxidation, that consists in applying an anodic polarization of several tens of volts to the metal, promoting the growth of the natural oxide layer with thicknesses from about 40 nm with anodizing potential 10 V, to about 250 nm at 100 V . At potentials higher than 100 V the anodizing begins to cause the insaturation of microarcs in the insulating oxide layer; in this regime, called “anodic spark deposition (ASD)” or “plasma electrolytic oxidation (PEO),” the oxide grows much more, reaching the thickness of several micrometers but switching from a compact to a porous structure …”

Combined Galvanostatic and Potentiostatic Plasma Electrolytic Oxidation of Titanium in Different Concentrations of H2SO4

“…Microstructured oxide layers on titanium, produced by plasma electrolytic oxidation (PEO), are of great interest for various applications, including bioengineering, architecture, photovoltaic and sensing technology [1,2]. In gas sensors, PEO films on titanium exhibit a number of interesting properties.…”
