ADVANCEMENT IN ELECTROPHORETIC DEPOSITION HYDROXYAPATITE BIOCERAMIC COATING

Hydroxyapatite (HAP) coating is considered to be the best type of biomedical material for replacing hard tissues of human body so far. Electrophoretic deposition is a new technique of preparing coatings, which can solve various disadvantages existed in the traditional technology for preparing HAP bioceramic coatings. This paper provides a comprehensive information on the survey of the electrophoretic deposition of hydroxyapatite bioceramic coating at home and abroad. The process flow and process parameters of the electrophoretic deposition are given . Various factors affecting the hydroxyapatite electrophoretic deposition coating are discussed in detail. Envisagement and prospects in the field are put forward eventually.
