摘要

In this paper, the applications and qualifications of biomedical materials are introduced. In regard to the hard tissue implants, the biocompatibility can be improved by preparing various bio- ceramic and bio- glass coatings. In view of this, the principles, characteristics, and applications of surface modi. cation (plasma spraying, electrostatic spray deposition, micro- arc oxidation, pulsed laser deposition, sol-gel deposition, and magnetron sputtering) in biomedical materials are reviewed. In addition, the research direction of improving biocompatibility by surface modi. cation is presented.
