Investigation into the Electrochemical Corrosion Characteristics of As-Built SLM Ti-6Al-4 V Alloy in Electrolytic Environments

In this investigation, the study compares the corrosion performance of wrought and Selective Laser Melting (SLM) Ti-6Al-4 V alloys utilized in biomedical settings through a combination of microscopic and electrochemical techniques. The microstructural analysis is conducted alongside Potentiodynamic testing and weight loss measurements, ensuring a thorough examination of corrosion behavior with high precision. Following immersion in Simulated Body Fluid (SBF) solution for six days, specimens undergo re-immersion, initiating polarization scans by ASTM G5 guidelines. To ensure equitable comparison, the exposed surface area of both conventional and SLM samples is minimized by masking off the entire face with the spot weld. This investigation contributes to understanding the corrosion resistance of Ti-6Al-4 V under different manufacturing processes, offering insights crucial for enhancing long-term performance and biocompatibility in biomedical implants. Using microscopic and electrochemical methodologies, including Potentiodynamic studies, comprehensively evaluate corrosion behavior. At the same time, SBF is a relevant medium for mimicking physiological conditions, facilitating a more accurate assessment of material performance in biomedical applications.
