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.
本研究的目的是根据快速仿生程序，在商用多孔纯钛种植体表面制备一层致密、坚固且薄的磷酸钙涂层。钛板经过抛光、喷砂、清洁并用氢氟酸和硝酸的混合物处理后，分为两组，即A组和B组。A组标本未进行任何处理。B组标本用48%硫酸和18%盐酸的混合物处理。所有标本在SBF-A溶液中浸泡1天。然后将标本浸入SBF-B溶液中2天。两组所有标本表面均沉积了一层薄的磷酸钙涂层，该涂层由形态良好的晶体组成，经证实是羟基碳酸磷灰石（HCA）和磷酸八钙（OCP）的混合物；涂层的钙磷比为1.51。通过快速仿生程序在多孔纯钛表面沉积了一层薄的碳酸磷酸钙涂层。
