Abstract

Additive manufacturing (AM) is the process of building 3D objects by layer-upon-layer. AM became a promising technique in various applications as automotive, aerospace and biomedical applications. The AM provides a flexible and versatile technique to produce complex shapes in short time using vast materials in a cost-effective way. So, AM has been successfully utilized to produce complex shaped biomedical implants using a wide range of biomaterials. Metallic Glasses (MG) proved to be an excellent material for biomedical implant applications because of their superior tribological and corrosion properties. However, the microstructure is characterized as a composite of different phases with vastly different mechanical properties such as ductility, strength, resistance to wear, creep and fatigue. A major challenge to utilize AM to fabricate large objects made of MG is the difficulty to preserve the amorphous structure in larger sizes. To get the superior properties benefit of MG in fabricating large objects, the coating of MG on a metallic substrate using laser cladding technique is proposed in this research work. Laser cladding (LC) is considered an outstanding technique to produce MG coating on metallic alloys substrate. This chapter discusses the various effects of LC parameters on the microstructure, phases formation, mechanical and tribo-corrosion properties of the MG coatings. Also, cytotoxicity and biocompatibility of MG are discussed.
