Biocompatible Ti₃Au-Ag/Cu thin film coatings with enhanced mechanical and antimicrobial functionality.

ABSTRACT:

Background

Biofilm formation on medical device surfaces is a persistent problem that shelters bacteria and encourages infections and implant rejection. One promising approach to tackle this problem is to coat the medical device with an antimicrobial material. In this work, for the first time, we impart antimicrobial functionality to Ti₃Au intermetallic alloy thin film coatings, while maintaining their superior mechanical hardness and biocompatibility.

Methods

A mosaic Ti sputtering target is developed to dope controlled amounts of antimicrobial elements of Ag and Cu into a Ti₃Au coating matrix by precise control of individual target power levels. The resulting Ti₃Au-Ag/Cu thin film coatings are then systematically characterised for their stru
