Characterization of TiNb Films on Ti Alloys for Hard Tissue Replacement

Abstract:

We present here a study of coatings prepared from β-Ti binary alloy Ti-39wt%Nb, a promising metallic material. TiNb is a highly corrosion-resistant and non-toxic material that is potentially applicable as a biomaterial. TiNb coatings can be prepared on substrates of widely-used materials, and promise not only improved properties but also a less high price of potential TiNb implants. A TiNb film can also be used as a barrier for limiting the potential diffusion of some allergens and toxic elements from the substrate to the surface, which can be influenced by layer properties. We deposited thin layers of TiNb by magnetron sputtering, which provides excellent layer properties in applications. These layers were prepared on substrates made from Ti, Ti alloys (Ti39Nb and Ti6Al4V) and stainless steel AISI316. The aim of our work was to characterize the structure and the mechanical properties of the layers, in dependence on the type of substrate, for application as coatings for medical implants.
