MICROSTRUCTURE AND MECHANICAL PROPERTIES OF NANOSTRUCTURED TI-22NB-10ZR COATINGS

The design of implants and functional prostheses requires superficial modifications that promote fast and lasting osseointegration. Magnetron sputtering enables to design nanostructured and textured β-Ti rich Ti-22Nb-10Zr (wt.%) coatings with variable mechanical properties (hardness and Young’s modu...
