微弧氧化改性二氧化钛生物活性膜的研究进展

Research progress of bioactive titania film based on biological treatment by microarc oxidation

微弧氧化是一种表面处理的新技术,在钛表面采用微弧氧化技术将会得到一层多孔状的具有生物活性的二氧化钛膜。该膜具有生物相容性好、与组织结合强度高、愈合时间短的特点,具有一定的临床应用价值。本文就微弧氧化技术的发展历史和现状、基本原理、膜层的结构和性能、生物活性作一简单综述。

As a new surface technology, microarc oxidation can be applied to the ceramic coating with bioactivity on Ti alloy. With good biocompatibility, high bond strength and short healing period, the film is worth applying to clinical operation. In this paper such information of microarc oxidation is reviewed as its developing history, research progress and basic principle. The structure, properties and bioactivity of the ceramic coating are also introduced.
