| Outline of Final Research Achievements |
The purpose of the present study is to develop a novel implant material which has a superior biocompatibilities and high strength by means of a coating technology. In this study, the cold spray technique was selected and used as surface modification method of a titanium alloy for the development of implant material; the porous pure titanium coating was sprayed on a titanium alloy, Ti-6Al-4V, by using the cold spray technique. The influences of spray conditions and post-sprayed heat treatments on the mechanical properties of the cold sprayed biomedical coatings were investigated. It was revealed from the experimental results that the developed biomedical titanium coatings had a low elastic modulus, high adhesion and enough tensile strength. The cold sprayed biomedical coatings developed in this work have enough fatigue properties.
