Development of lotus-like hydroxyapatite coating on HELCDEB treated titanium by pulsed electrodeposition

• PED of lotus flower-like HAP on HELCDEB treated Ti was achieved successfully.
• HAP coated HELCDEB treated Ti shows enhanced bioresistivity.
• The as-coated Ti is bioresistive, better candidate for biomedical applications.

Pure titanium (Ti) was irradiated using high energy low current electron beam (HELCDEB) with a concentrated energy flow of 500 keV at 1.5 mA beam current. The irradiated Ti surface was coated with hydroxyapatite (HAP) by pulsed electrodeposition (PED) with the optimum concentration of 2000 ppm H2O2 at current density 1 mA/cm2. The HRSEM characterization of HAP coating on the HELCDEB treated Ti substrate exhibited lotus flower-like morphology. The corrosion resistivity of HAP coating on the HELCDEB treated Ti was investigated by the potentiodynamic polarization technique, which shows desired bioresistivity in simulated body fluid (SBF). The as-coated HAP can immensely serve as a potential candidate for biomedical applications.
