Electrophoretic enhanced micro arc oxidation of ZrO2–HAp–TiO2 nanostructured porous layers

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

“…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].…”

Characterization of ZrO2 ceramic coatings on ZrH1.8 prepared in different electrolytes by micro-arc oxidation

“…However, it is known that the MAO is a complex process that combines electrochemical and electrothermal process. In this process, the local temperature inside the discharge channels reaches up to 1 9 10 3 -1 9 10 4 K [33], which is high enough to melt the ZrH 1.8 substrate as well as ZrO 2 ceramic coating. Besides, the oxides can be preserved under the high cooling rate of electrolyte.…”

Fabrication and characterization of nano-HA-45S5 bioglass composite coatings on calcium-phosphate containing micro-arc oxidized CP-Ti substrates

“…In this respect, chemical compounds also can be incorporated from Ca and P containing electrolytes to enhance high biocompatibility and cell attachment [30][31][32]. Most of previous works were focused on one-step approach for utilizing MAO and EPD at the same time [33][34][35][36]. They used one suspension/electrolyte solution and both of these processes were performed simultaneously for the final coating [33][34][35][36].…”

They used one suspension/electrolyte solution and both of these processes were performed simultaneously for the final coating [33][34][35][36]. Nie et al [37] developed a double layer HA/TiO 2 coating on titanium alloys with HA as the top layer and a dense TiO 2 film as the inner layer to improve biochemical stability in the corrosive environment of the human body via a hybrid combination of micro-arc oxidation and electrophoretic deposition.…”
