TITANIUM SUBSTRATE FOR BIOCOMPATIBLE IMPLANT COATED WITH HYDROXYAPATITE/TITANIA DOUBLE LAYER AND A COATING METHOD OF THE SAME

摘要

The present invention relates to a method for coating on a biocompatible implant, and in particular to a method for implementing a double layer coating process on a titanium metal substrate for a biocompatible implant having an excellent mechanical property based on an outer layer of a hydroxyapatite(HA) and an inner layer of a titania. A fast osseointegration is implemented through an excellent tissue reaction by a hydroxyapatite in an outer layer, and in an inner layer, a surface of a titanium for a biocompatible implant has an anti-corrosion and anti-abrasion property by a titania in such a manner that a hydroxyapatite/titania double layer is concurrently formed based on a surface coating method among the methods for a surface process of a titanium for a biocompatible implant.
