Abstract
Way for applying tantalum coating with a given structure to the surface of an alloy with a shape memory effect NiTi to increase the biocompatibility of implants from this alloy is presented. The coating was synthesized by direct current (DC) magnetron sputtering. The changes sequence of the structural-phase states depending on the thickness of the coating, that is, the rate of its deposition, has been established. It is shown that at a low magnetron power, ∼14 W in present study, a single-phase α-Ta coating with a bcc structure and a high degree of perfection of the crystal lattice is successfully synthesized on the titanium nickelide surface.
