“…Results show that only anatase phase forms at 250 V. Since this voltage was not strong enough to compel alumina particles to incorporate into coatings in large volumes, the alumina characteristic peaks remained latent in this voltage. Anatase forms due to the electrochemical oxidation of titanium substrates in alkali media (sodium phosphate electrolyte) through to the following reactions [18,19,49,54]:…”

“…Ceramic coatings have been recently found promising for a variety of industrial applications in order to improve wear resistance [1][2][3], corrosion resistance [4][5][6][7][8], heat resistance [9], biocompatibility [10][11][12][13], and photocatalystic activity [14][15][16][17][18][19] of metals and alloys. These coatings are fabricated by different techniques such as oxidation of the metal surfaces [3,[20][21][22], sol-gel process [19], vapor phase deposition [23,24], electrophoresis [25], and thermal spray [26,27].…”

“…MAO coatings on titanium alloys are effective as chemical barriers against the release of metal ions from the substrates and can enhance the corrosion resistant of titanium alloys [49]. MAO is an efficient process enabling us to fabricate ceramic coatings with different chemical compositions in only one step [50][51][52][53][54][55][56][57][58].…”

“…It was found that vanadia was partially doped into the titania lattice and dispersed in its matrix as well. We fabricated V 2 O 5 -TiO 2 layers via MAO process and proposed a formation mechanism for the first [27,28].…”
