Innovative fabrication of ZrO2–HAp–TiO2 nano/micro-structured composites through MAO/EPD combined method

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].…”

“…For example, if the electrolyte contains insoluble negatively charged particles, a composite coating consisted of an oxide matrix with the dispersed ceramic particles forms on the surface of anode [11,29,48,49]. This new fabrication technique is called Electrophoretic Enhanced Micro Arc Oxidation (EEMAO) which has the advantage of both micro arc oxidation and electrophoretic deposition methods [10,48,49]. It should be noted that oxide particles assume a negative charge when pH of the electrolyte exceeds the PZC (Point of Zero Charge) of particles.…”

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.…”

Surface and anticorrosion properties of hydrophobic and hydrophilic TiO2 coatings on a stainless-steel substrate

“…because of their unique physiochemical properties and good chemical stability. [7][8][9] Here we report on a comparison of the surface and anticorrosion properties of double-layer, dual-size (30 nm and 300 nm) FAS-TiO 2 /epoxy and as-received TiO 2 /epoxy coatings. We show that the order of the nanoparticle deposition plays an important role in the wetting and the morphological properties of the coatings.…”
