“…Usage of stents that represent a system of the stainless steel substrate with titanium or tantalum coating allows combining the suitable mechanical properties and bioinertness [ 3 , 4 , 5 ]. Tantalum is characterized by a good plasticity, high strength, wear resistance, weldability, corrosion resistance, infusibility, biocompatibility, and it is clearly visible in X-rays and magnetic resonance imaging [ 6 , 7 ]. In addition, due to its properties, tantalum is widely used not only in electronics [ 8 , 9 ], protective coatings [ 10 , 11 ], anti-corrosion coatings [ 12 , 13 ], optical coatings [ 14 , 15 , 16 , 17 ], chemical industry [ 18 ], but also in biomedicine [ 19 , 20 , 21 , 22 , 23 , 24 ] (orthopedics and dentistry [ 25 , 26 , 27 , 28 , 29 ], endovascular stents, and neurosurgical implants [ 30 ]).…”
