Nickel Titanium alloys have proved to be a perfect choice for materials used for medical devices like catheters, pacemakers, and stone removal mesh. However, there are challenges related to shape and size modifications. Improvements are needed in porosity, radiopacity, superelasticity, and fatigue strength. This paper includes synthesis of porous NiTi alloys via the sintering process, followed by surface treatments such as dry heating, boiling in water, and passivation. The corrosion resistance of treated and untreated samples was evaluated. Results show improved corrosion resistance for etched, boiled, and passivated samples, confirming their suitability for biomedical implants.
