Abstract
The aim of this research was to study the properties of nanohydroxyapatite (nanoHAp) and nanohydroxyapatite, doped with nanosilver (nanoHAp/nanoAg), coatings obtained by an electrophoretic deposition process. The suspensions was prepared by dispersing 0.1 g of HAp nanopowder for nanoHAp coatings and 0.1 g of nanoHAp and 0.025 g nanoAg for nanoHAp/nanoAg coatings. The deposition was carried out for 1 min at 50 V voltage followed by drying at room temperature for 24 h and heating at 800°C for 1 h in vacuum. The thickness of the nanoHAp and nanoHAp/nanoAg coatings was found as of about 5 µm. The corrosion behavior tests made by potentiodynamic methods brought out slightly higher values of corrosion current for nanoHAp coatings and nanoHAp/nanoAg coatings as compared to the reference Ti13Zr13Nb specimen. The nanohardness of the nanoHAp coatings achieved 0.020 0.004 GPa and of the nanoHAp/nanoAg coatings 0.026 0.012 GPa. Nanoscratch test of the nanoHAp and nanoHAp/nanoAg coatings revealed an increased Critical Friction (mN) in the presence of nanosilver particles. The wettability angles decreased for nanoHAp/nanoAg coatings comparing to pure nanoHAp coatings on titanium alloy.
