Abstract

Language:

The corrosion behavior of TiN coated NiTi-Shape Memory Alloy, Ti6Al4V, and 316L Stainless Steel implant alloys in artificial physiological solutions were investigated through electrochemical testing. The aim was to evaluate the corrosion stability and elemental out-diffusion resistance of these materials, which are critical for their application in biomedical fields. Utilizing the cathodic arc physical vapor deposition method for film deposition, surface morphology and composition were analyzed using scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDAX) and X-ray diffraction (XRD). The study also employed inductively coupled plasma atomic emission spectrometry (ICPAES) to quantify ions leached from each specimen after immersion in artificial physiological solution for sixteen weeks. Results indicated that the corrosion stability, elemental out-diffusion resistance, and microhardness were all enhanced due to the TiN coating treatment. These findings contribute to the understanding of how surface modifications can improve the performance of metallic implants in physiological environments.
