ABSTRACT
The aim of this study was to elaborate a dense, strong and thin calcium-phosphate coating on commercial porous pure titanium implant surface in the light of a fast biomimetic procedure. After being polished, sandblasted, cleaned and treated with the mixture of HF and HNO3, the titanium plates were divided into two groups, namely group A and group B. The specimens of group A were free from any treatment. The specimens of group B were treated with the mixture of 48% H2SO4 and 18% HCl. All specimens soaked in SBF-A solution for 1d. Then the specimens were immersed in the SBF-B solution for 2 d. A thin calcium-phosphate coating was deposited on all the specimens of the two groups, the surface consisted of well-formed crystals, which were proved to be the mixture of hydroxycarbonated apatite (HCA) and octacalcium phosphate (OCP); the coating's Ca/P rate was 1.51. A thin carbonated calcium-phosphate coating was deposited on porous pure titanium by the use of the fast biomimetic procedure.
