Paper Title:
Corrosion Behaviour of Cardiovascular Stents
Abstract:
Cyclic Potentiodynamic polarization studies were conducted to
compare the corrosion resistance of Nitinol cardiovascular stents and
stainless steel stents. The tests is to simulate the corrosion behavior of
the stents under body condition using Phosphate Buffered Saline (PBS)
solution at 37oC and following the ASTM F2129-01, Item 2, WK1749,
Standard. The results of this
study indicate that both NiTi and SS stents exhibit high corrosion
resistance in the PBS solution. The SS stents show slightly better
corrosion resistance than the Nitinol stents.
The electropolished Nitinol stents appear to have slightly better
corrosion resistance compared with the unpolished ones.
