Customisation of PVD coatings for biomedical devices

Abstract

In recent years, physical vapor deposition (PVD) has emerged as a powerful technique for surface modification, offering a wide range of possibilities to improve the properties of medical devices. This review explores the fundamentals and versatility of PVD coatings in biomedical applications, highlighting their potential to revolutionise the field. Biocompatibility is crucial in successfully integrating medical devices with the human body. The precise modification of thin films to improve biocompatibility, reduce adverse reactions, and promote better tissue integration is discussed. Osseointegration, another critical factor for the success of orthopaedic and dental implants, is also explored in the context of magnetron sputtering coatings. The ability of these coatings to provide a bioactive surface that promotes bone cell adhesion and growth is analyzed, shedding light on the potential of tailor-made coatings in improving implant success rates. Infections associated with medical devices pose a significant challenge in healthcare settings. Strategies, such as the incorporation of antimicrobial agents and surface modifications, are discussed, highlighting the potential of this waste-zero technique in effectively addressing this critical issue. Overall, the versatility, coupled with the ability to enhance corrosion resistance, mechanical properties, tribological performance, biocompatibility, osseointegration, and antimicrobial activity, makes PVD coatings highly promising for improving the performance and functionality of medical devices. Continued research and development in this field will undoubtedly lead to further advancements in PVD coatings, revolutionising the biomedical industry. • Reviews recent advances in magnetron sputtering for biomedical devices • Evaluates PVD coatings for corrosion resistance, durability, biocompatibility, and infection control • Links structure–property relationships to coating design strategies
