摘要

Studies show that calcium phosphate coatings on titanium implants improve osseointegration at the implant-bone interface, due to the mineral biocompatibility. Titanium implants can be coated with calcium phosphates by a biomimetic precipitation method. This work studied a biomimetic method under a simplified solution with calcium and phosphorus ions. As substrates, commercially dense titanium sheet and macroporous titanium samples produced by powder metallurgy were used, both ASTM F67 grade 2. The substrates were submitted to chemical and heat treatment and then immersed in the solution for 10 days. Samples characterization was performed by Optical Microscopy (OM), Scanning Electron Microscopy/Energy Dispersive Spectroscopy (SEM/EDS), low angle X-ray Diffractometry (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). Powder metallurgy successfully produced macroporous titanium substrates. Calcium phosphate coatings were deposited on both substrates, confirmed by FTIR bands. Such results indicated the potential of this methodology for calcium phosphate coatings on titanium substrates.
