摘要：

Using the methods of SEM, EDS, and optical microscopy, a large number of non-metallic inclusions are revealed on the pore surface of a TiNi-based SHS-alloy. According to the XRD and EDS data, the surface is chemically and structurally inhomogeneous and its composition is close to that of a Ti4Ni2(O,N,C) intermetallic oxycarbonitride. An optical microscopy examination demonstrates that the entire surface is coated with a semi-transparent film. The results of XRD analysis allow assuming that in the formation of the surface of the TiNi-based porous material surface a significant role is played by the glassy phase and wollastonite, which imparts special physical-chemical properties and high biocompatibility to the alloy. SEM examination of morphological features of evolution of the mesenchymal cells on the pore surface of the TiNi-based SHS-material within the period 1-28 days shows that on the 7-14-th day the main elements of loose fibrous connective tissue are formed. Dense connective tissue is formed by the 21-st-28-th day.
