Biodegradation behavior of micro-arc oxidized AZ31 magnesium alloys formed in two different electrolytes

Characterization and corrosion resistance of pure Mg modified by micro‐arc oxidation using phosphate electrolyte with/without NaOH

“…). In MAO coatings prepared using phosphate‐based electrolytes, besides MgO (periclase), the formation of Mg 3 (PO 4 ) 2 (farringtonite) is also expected . Similar to the O 2− ions, inward diffusion of PO 4 3− ions could lead to the formation of Mg 3 (PO 4 ) 2 according to the following reaction: …”

Review of the biocompatibility of micro-arc oxidation coated titanium alloys

“…Hence, it is imperative to properly select the electrolyte composition and concentration so that a rapid metal passivation can be promoted and the sparking voltage can be easily reached [70]. Generally, NaOH/KOH is used as the base electrolyte while phosphate [71,72], fluoride [70,73], and silicate [72,74] are used as the primary electrolyte additives in MAO process.…”

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].…”
