Abstract
The aim of the current study is to develop and evaluate antibacterial and biocompatible refractory high-entropy alloy (RHEAs) film using RF magnetron sputtering technique. For this purpose, Ti1.5ZrTa0.5Nb0.5W0.5 RHEA film and its Ag nanoparticle doped analog (with an Ag content of 9 atomic %) were deposited on Ti6Al4V substrate. The microstructural characterization revealed the homogenous distribution of the constituent elements and amorphous structure of the deposited films. The antibacterial activity of Ag nanoparticles doped RHEA film was compared with that of undoped film and uncoated Ti6Al4V. The results indicated that doping Ag nanoparticles reduced the colony forming unit of P. Aeruginosa and S. Aureus bacteria by 98.5% and 90.9%, respectively. In addition, healthy C2C12 mouse muscle myoblast cells adhered and proliferated perfectly on the surface of antibacterial Ag nanoparticles doped RHEA film with no indication of toxic effect, demonstrating promising biocompatibility in addition to its strong antibacterial property.
