Preparation of Bio-Composite Coatings on Titanium Substrate by Electrostatic Spray Deposition

In this research, the most modern deposition technique used will be utilized for biomedical applications is Electrostatic Spray Deposition (ESD), which focused on enhancing the corrosion resistance as well as biocompatibility of commercially pure titanium substrate by constructing bio composite coating, various percentages (2, 6, and 10) wt.% of Hydroxyapatite (HAP) powder were combined with (98, 94, and 90) wt.% of polymethyl methacrylate (PMMA) powder, and the same percentages (2, 6, and 10) wt.% of Nickel Oxide (NiO) powder also combined with (98, 94, and 90) wt.% of PMMA. The effects of HAP and NiO percentages in the PMMA matrix on the surface characteristics of titanium were analyzed. The FESEM, XRD, contact angle, and anti-bacterial test demonstrated that the coating layer was successfully made consistent throughout and devoid of cracks. the samples exhibited favorable wetting qualities and inhibited bacterial growth.
