Surface Characterization Of Ultra-Short Laser Textured Titanium For Biomedical Application

Surface modification is assuming a strategic role for interface properties tuning, either in the case of interaction between implant and tissue or substrate and coating. However, sometimes a lack of integration between a comprehensive implant surface characterization and, for instance, biological phenomena occurrence can be detected, dealing with inherently different fields of study. This work aims to provide a suitable approach that could allow correlation between substrate features and surrounding environment alterations, whether it biological or not. A chain of characterization techniques and their role within the research path will be explored employing a case study: biomedical Ti6Al4V titanium alloy treated with ultra-short laser for surface texturing and its features and interactions with a natural polymer-based composite as a potential coating.
