Development of Adhesive, Bioactive and Antibacterial Titania Sol-Gel Coating on Titanium Substrate by Dip-Coating Technique

The sol-gel method provides a wide variety of applications in the medical field. One these is formation coatings on metal implants. containing specific additive can enhance or improve existing surface properties substrate. In this work, titania were doped with two forms silver (AgNO3, Ag3PO4) and synthetic hydroxyapatite applied titanium samples by dip-coating technique. After drying slow firing, all characterized scanning electron microscopy. Thin successfully prepared excellent adhesion to substrate (measured ASTM D 3359-2), despite cracks. Coatings demonstrated 100% antibacterial effect against Escherichia coli after 24 h. bioactivity tested modified simulated body fluid under static-dynamic conditions was confirmed bone-like precipitation. To better understand interaction (SBF), changes Ca2+ (PO4)3− ions concentrations pH values studied.
