Surface Modification Techniques for Corrosion Control in Biomedical Implants

Abstract

This chapter rigorously examines state-of-the-art surface modification techniques aimed at mitigating corrosion in biomedical implants. It begins by emphasizing the prevalence and critical importance of biomedical implants, setting the stage for an in-depth exploration of fundamental corrosion mechanisms and their intricate relationship with surface properties. The discussion extends to advanced surface modification strategies, including physical, chemical, and biological techniques, with a focus on practical applications for achieving corrosion resistance and biocompatibility. The practical implications of these approaches are underscored through real-world case studies in the fields of biomedical implants (orthopedics, neural, dental, and cardiovascular implants). Scientifically, this work contributes by providing a comprehensive study of the tailored implementation of surface adjustment strategies, addressing the unique needs of each implant type. The exploration of predictive modeling techniques for corrosion resistance assessment and a critical evaluation of current limitations adds scholarly depth to the chapter. In conclusion, the chapter underscores the pivotal role of surface modification in ensuring the longevity of biomedical implants, offering insightful perspectives and recommendations for future research endeavors.
