| Outline of Final Research Achievements |
The purpose of the present study is to develop a novel implant material which has a superior biocompatibilities by using the cold spray technique with the hydroxyapatite (HAp) uniformly dispersed titanium spray powder.
To achieve superior biocompatibility, the HAp dispersed titanium coating was coated on the Ti-6Al-4V alloy with the porous titanium bond coating. The effects of spray parameters and post-sprayed heat treatment were investigated. In addition, the empirical equation to predict the anisotropic elastic modulus of thermal spray coating was proposed based on the multiscale finite element analysis. And also, the adhesion strength of the developed coating system was evaluated by using the in-situ shear delamination test method.
