Abstract
The invention relates to the field of medical titanium alloy materials, in particular to an anti-infection medical titanium alloy. The medical titanium alloy comprises chemical components including, by weight percent, 5.5%-6.5% of Al, 3.5%-4.5% of V, 0.2%-4.0% of Ga and the balance Ti and other inevitable impurity elements. The proper amount of Ga element is added in a medical Ti6Al4V alloy matrix, and accordingly the Ti6Al4V medical titanium alloy is endowed with the excellent bacterium infection resisting function. The alloy can be widely applied to various medical titanium alloy medical instruments used in the orthopedics department, the stomatology department and other clinic fields, and bacterium infection risks caused during usage of existing implanted material titanium alloy instruments can be further obviously reduced.
Description
technical field [0001] The invention relates to the field of medical titanium alloy materials, in particular to an anti-infection medical titanium alloy. Background technique [0002] Due to its non-magnetic, non-toxic, excellent biocompatibility, good wear resistance and corrosion resistance and comprehensive mechanical properties, medical titanium alloy is a kind of medical metal material widely used in clinical practice, and has been widely used in artificial joints, Fracture internal fixation devices, spinal orthopedic internal fixation systems, dental repairs and many other implanted devices. Ti6Al4V is the first generation of medical titanium alloy widely used in the manufacture of implant devices, and its main alloying elements are Al (5.5-6.5wt.%) and V (3.5-4.5wt.%). Compared with pure titanium, Ti6Al4V is an α+β titanium alloy with excellent mechanical properties and good processing properties. It has a long history of clinical application as surgical repair mater...
