The NiTi alloy is extensively utilized in the biomedical sector for its remarkable mechanical properties, including superelasticity and shape memory. This study aimed to explore the corrosion resistance of NiTi alloys, focusing on numerous methodologies designed to enhance their biocompatibility and mitigate nickel release. Various techniques such as anodization, heat treatments, and coatings were examined to assess their impact on the alloy's corrosion resistance in simulated body fluids. Electrochemical tests using a simulated body fluid (SBF) solution revealed a significant reduction in corrosion current density for hydroxylapatite/zirconia-coated samples compared to uncoated NiTi, demonstrating almost 60 times lower leakage. Furthermore, the breakdown potential of coated samples was notably stable across tested potentials, indicating enhanced performance over bare NiTi. The correlation between electrolyte composition and corrosion susceptibility was highlighted, underscoring the complexity of interactions affecting alloy behavior. Results indicated that surface treatments and coatings can significantly improve the performance of NiTi alloys in biomedical applications, thereby enhancing their viability for long-term usage in medical implants.
