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 order to achieve the purpose, the cold spray technique was selected and used to surface modification method of a titanium alloy. 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 change in the microstructure of the coating by the cyclic compressed indentation loading was investigated.
