Adhesion Strength of Sol-Gel Derived FHA Coating on Laser Gas Nitrided Pure Ti

Abstract:

Article Preview

Fluor-hydroxyapatite (FHA) films were deposited on titanium and laser gas nitrided titanium substrates using sol-gel technique respectively. Typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment from 600°C to 800°C. The obtained films were uniform and dense, with a thickness of 5 μm. The 3-D TiN dendritic structure fabricated on the surface of Ti plate using laser gas nitriding technique in advance should be help anchor the HA/FHA coating and improved the interfacial adherence significantly compared with the naked titanium surface.
