| Summary: | Заглавие с экрана The results of the investigation of a terrace-like topography on the surface of the pore walls in biocompatible porous permeable TiNi-based material, obtained by sintering are presented in the paper. For this, samples of a porous TiNi alloy were obtained by single and double sintering at various temperature-time regimes. Structural studies of TiNi-based powder obtained by method of calcium hydride reduction are presented. The powder is the starting material for the production of porous samples. It is established that the powder has a double morphology - spongy and compact. On the surface of the spongy particles, weakly expressed elements of the terrace-like topography were found. The presence of a developed rough terrace-like structure was revealed in the study of samples obtained by various methods of sintering. An increase of the sintering temperature activates mechanisms of surface and bulk diffusion, which positively affects the development of the terrace-like topography. However, the high sintering temperatures lead to an increase in volumetric shrinkage and to the growth of particles of secondary phases enriched in titanium Ti[4]Ni[2] (O, N, C). Введение. Применение пористых имплантатов на основе никелида титана (TiNi) позволяет. |
