Surface modification methods of titanium (Ti)-based implant materials for biomedical applications

Abstract

This book chapter provides a comprehensive overview of surface modification techniques applied to titanium (Ti) and Ti-based alloy implants in the context of biomedical applications. Titanium alloy bioimplants play a crucial role in modern healthcare, offering solutions for tissue repair, organ replacement, and medical device integration due to their superior mechanical properties. However, their successful integration into the human body hinges on their surface properties, including biocompatibility, durability, and functionality. The current chapter commences by emphasizing the pivotal role of surface modification in optimizing bioimplants. It explores a spectrum of techniques encompassing physical surface modifications, chemical surface modification, as well as mechanical approaches. Throughout, this chapter highlights the significance of adapting surface modifications to the unique requirements and challenges posed by different bioimplants. In summary, this chapter offers a valuable resource for researchers, clinicians, and biomedical engineers, presenting the latest advancements in surface modification techniques for bioimplants. These insights have the potential to advance the development of safer, more effective, and highly durable biomedical devices, ultimately improving patient care and outcomes. © 2025 selection and editorial matter, Abhilash P M, Kishor Kumar Gajrani and Xichun Luo.
