Growth by plasma electrolysis of zirconium oxide films in the micrometer range

How deposition parameters affect corrosion behavior of TiO2-Al2O3 nanocomposite coatings

“…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]. To improve wear, corrosion and photocatalytic properties of valve metals including Al [7,28,29], Ti [4,[30][31][32][33], Mg [1,[34][35][36][37], and Zr [38][39][40], surface oxidation techniques, such as Micro Arc Oxidation have been successfully used. Micro Arc Oxidation (MAO) process [41][42][43] is a relatively new method to oxidize metallic surfaces which has attracted many research works in recent years.…”

An innovative technique to simply fabricate ZrO2–HA–TiO2 nanostructured layers

“…The most important advantage of the MAO-derived layers is that they are not only porous, but also uniformly coated on metal surfaces with complex geometry. Moreover, MAO coatings usually exhibit good adhesion to substrates [43][44][45][46][47]. It is known that MAO involves in more complex plasma-enhanced physico-chemical processes, including micro-arc discharge, diffusion, plasma chemical reactions, and cataphoretic effects, in which micro-arc discharge can generate high temperature in the discharge channels, sintering the subsequent processes formed coatings [48].…”

The effect of chemical treatment on apatite-forming ability of the macroporous zirconia films formed by micro-arc oxidation

“…Moreover, MAO coatings usually exhibit good adhesion to substrates. Although MAO modification of zirconium and its www.elsevier.com/locate/apsusc Available online at www.sciencedirect.com alloys was recently performed as described in details elsewhere [16][17][18][19], the obtained films were always filled with cracks on their surfaces. In our previous work [20,21], zirconia films containing Ca and P on zirconium were obtained by MAO in electrolytes containing calcium acetate monohydrate and bglycerophosphate disodium salt pentahydrate.…”
