ABSTRACT:
A titanium composite having a coil-shaped skeletal structure on the surface, comprising a titanium or titanium alloy substrate and one or more layers of a coil-shaped skeletal titanium or titanium alloy structure that is firmly attached to the surface of said substrate and a process for producing a titanium composite having a coil-shaped skeletal structure on a surface of a titanium or titanium alloy substrate, which comprises: providing a coating composition which is a mixture of a titanium or titanium alloy powder with a binder; applying said composition in such a manner that titanium or titanium alloy coils which are to form the coil-shaped skeletal structure are firmly attached to both themselves and to the titanium or titanium alloy substrate; the heating the assembly either in vacuo or in an inert atmosphere so that the titanium or titanium alloy powder in the applied coating composition is sintered to have the coil-shaped skeletal titanium or titanium alloy structure attached firmly onto the titanium or titanium alloy substrate.
