N2 - This two-part study evaluates the antimicrobial efficacy of tantalum-copper and niobium-copper coatings, applied via magnetron sputtering (MS) on three dimensional (3D) printed porous Ti6Al4V (Ti-64) alloy scaffolds and gas-abrasive treated Ti-64 alloy, against Staphylococcus aureus and Candida albicans. Scanning electron microscopy (SEM) with energy-dispersive X-ray (EDX) analysis verified the application of coatings with 25 wt% copper, at thicknesses of 2 μm and 10 μm, to scaffolds (72% porosity) and roughened Ti-64 alloy (mean areal roughness of 4.6 ± 1 µm). The findings support the potential of these coatings in developing endoprosthesis implants with enhanced antimicrobial properties. Part I introduces the background research and describes the materials, methods and rationale for the present work.
