摘要：

We study the dependence of formation of calcium-phosphate coatings on commercially pure VT1-0 titanium on the parameters of plasma-electrolytic oxidation: deposition voltage (140-220 V) and duration (3-9 min). Hydroxyapatite-containing coatings with spheroidal structure are formed under a deposition voltage of 200 V. At the same time, the coatings with lamellar structure are formed under a voltage of 220 V. The formation of hydroxyapatite phase for both levels of voltage guarantees the highest corrosion resistance in Ringer's solution at 37 degrees C.
