Structure and Properties of Bioactive Titania Layer by Microarc Oxidization-Hydrothermal Synthesis

摘要:

在钛合金基体上通过微弧氧化形成含钙和磷的二氧化钛层，再经过水热合成转化为含羟基磷灰石的生物活性二氧化钛层，该膜层结合强度高，而且是多孔和均匀的。因此，该方法很适合钛合金植入体的生物活性表面改性。

Abstract:

The titania layer containing calcium and phosphate on titanium alloy substrate was formed by microarc oxidization and converted to the bioactive titania layer containing hydroxyapatite by subsequent hydrothermal synthesis. The porous bioactive layer has a high bonding strength. So, this technique is very suitable for the bioactive surface modification of titanium alloy implants.
