Processing, Characterization and Testing of Alloys and Metal Matrix Composites for Biomedical Applications

Dear Colleagues,

Metals and their alloys have been used for biomedical applications for many years. Metallic biomaterials must meet biocompatibility requirements, and, depending on the application, must have excellent toughness, elasticity, rigidity, strength, resistance to fracture, and wear and corrosion resistance. All these properties of metallic biomaterials are significantly affected by their processing technology and resulting microstructure, including their phase composition, grain shape and size, dispersed particles, solutes, and so on. Therefore, experimental studies on the relationships between processing technology, microstructure, and metallic implant properties are essential. The most commonly used metals for implants are stainless steel, CoCr alloys, and Ti alloys. Another category is represented by the metallic alloys used in dentistry; even these alloys are noble (based on Au, Ag, and Pt) or not (Ni-Cr alloy, dental amalgam). Other metals used for implants include tantalum (Ta), metallic glass, amorphous alloys, and biodegradable metals.

Biodegradable metallic materials have played an important role in biomedical applications. The use of degradable metals as the base material to prepare metal matrix composite materials is an excellent alternative to solve the problems related to the faster degradation of biodegradable metals. Biodegradable metals can thus be successfully combined with other materials to form biodegradable metallic matrix composites for biomedical applications and functions.

The effort placed into searching for new metallic biomaterials and biodegradable metal matrix composites as well as modifying existing implant materials is important for biomedical applications. The aim of this Special Issue is to present the latest achievements in the processing technology, structure development and characterization, surface modification, and properties testing of various alloys and metal matrix composites for biomedical applications. Topics include, but are not limited to, biodegradable metals, surface modifications for enhanced corrosion and biological responses, new metallic biomaterials, mechanical testing, CAD/CAM technology, coatings, osseointegration, and new trends in metallic biomaterials. This special issue of Metals invites innovative contributions in terms of full research papers and reviews from leading groups around the world. We also encourage the dissemination of this invitation to any colleagues that might be interested.
