Research Progress and Future Development of Nonferrous Biomedical Materials

Abstract

Nonferrous biomedical materials have developed rapidly in recent years. A variety of new nonferrous biomedical materials and devices that adapt to different in vivo environments and tissues have been developed. It is of both theoretical and practical values to make research plans to improve the clinical application level of new nonferrous biomedical materials and devices. This study clarifies the key performance requirements of the nonferrous biomedical materials, regarding corrosion resistance, wear resistance, fatigue strength and toughness, and biocompatibility. The research progress, development trend, and scientific issues of nonferrous medical materials for permanent implants, biodegradable nonferrous medical materials, porous nonferrous medical materials, and surface modification of nonferrous medical materials are reviewed. After summarizing the future research directions of various nonferrous biomedical materials, this study proposes the following development suggestions: (1) strengthening basic research and the development of key core technologies, (2) establishing a collaborative innovation community that integrates industry, education, research, medicine, and supervision, (3) formulating relevant standards and evaluation norms, and (4) developing a highly skilled professional training system, thereby providing a guiding reference for developing the new material industry and relevant cutting-edge technologies.
