Název v původním jazyce

Hydrogen embrittlement of biomedical shape memory Ni-Ti wire

Popis výsledku v původním jazyce

Equimolar NiTi alloy known as Nitinol, is a modern metallic material on which very high demands are placed. This alloy has been used for its unique properties, such as shape memory, superelasticity and pseudoplasticity. Nitinol also has very good corrosion resistance and applicability as a biomaterial. In medicine, Nitinol is most often used in the form of stents, which are used as reinforcement bottlenecks in the cardiovascular system or gastrointestinal tract, ortodontistic wires, orthopedic terminals of micro invasive surgery tools, tools for endoscopy and apertures or aneurysms. Successful use is subject to a manufacturer's declared stable mechanical properties of Nitinol. These properties can significantly influence a hydrogen deposited in the alloy, both due to the manufacturing process itself so that the resulting exposure in the environment. It was shown that even very low contents of hydrogen in the alloy leading to a substantial reduction in plasticity and strength of Nitinol, which may be one of the main causes of premature failure of medical implants in the specific environment of the human body.
