This abstract first appeared for US patent application 20250001493 titled 'ANTIMICROBIAL BIOCOMPATIBLE METAL ALLOY AND MANUFACTURE OF THE SAME

Original Abstract Submitted

to provide ti═cu alloy formulations and additive manufacturing process configurations for fabrication of a bulk metallic glass (bmg) product that is biocompatible and antimicrobial, compositions of ti-based metal alloy powder, including ti; cu within a range of 5-30 atomic percent; transition metal within a range of 0-50 atomic percent, wherein such transition metal is one or a plurality of zr, nb, ta, pd, and co, are disclosed. moreover, additive manufacturing processes disclosed herein are capable of fabricating a bulk metallic glass of one or a combination of following phasic structures: fully amorphous microstructure; amorphous beta titanium phase; amorphous copper phase; and amorphous (ti,m)2cu phase. the resulting biocompatible metal alloy product may be a medical device, particularly but not limited to a medical implant.
