Abstract
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 to surface modification method of a titanium alloy for the development of implant material; the pure titanium coating was sprayed on a titanium alloy, Ti-6Al-4V, by means of the cold spray technique. It was revealed in previous study that the cold sprayed porous Ti coating (CS-Ti coating) had a low elastic modulus, high adhesion and enough tensile strength in the post-sprayed heat treated (PSHTed) CS-Ti coating. In this study, the deformation behavior of the CS-Ti coating was observed in the SEM. In the PSHTed CS-Ti coating, the debonding of splats occurred after the enough plastic deformation.
