摘要

The paper studies the structure of TiNi wires of a diameter 60 μm obtained by the conventional technique followed by cryogenic treatment. X‑ray diffractometry, scanning electron microscopy (SEM) and energy dispersive spectroscopy reveal chemical and phase compositions of thin wires before and after cryogenic treatment. SEM is used to investigate biointegration of a spherical TiNi implant into soft tissues. It is shown that cryogenic treatment of thin TiNi wires provides the formation of two phases B2+B19’ in the structure that indicates to martensite stabilization after cooling. The high integration tie is demonstrated between body tissues both inside and on the surface of the spherical implant.
