Abstract
In this work we develop a technology for deposition of titanium nano-structured coatings on titanium plain washers by magnetron sputtering and investigate the influence of technological conditions on the structural parameters of the deposited titanium coatings. Magnetron sputtering of pure 99.99% titanium coatings on titanium washers VT1.0 and VT6.0, has been developed. It is shown that by this method it is possible to form coatings of pure titanium with a nano-relief surface. Titanium coatings under varying deposition parameters were characterized by Scanning Electron Microscopy and Atom Force Microscopy. It is shown that titanium coatings deposited by magnetron sputtering technique have a nano-granular structure. The maximum surface irregularities vary within ± 150 nm, and the grain sizes vary from 50 nm to 450 nm. The obtained result is of great interest for further investigation of the influence of titanium coatings morphology and its nano-dimensional characteristics on the biochemical mechanisms responsible for the process of bone remodeling around the implant. It is established that titanium coatings allow not only to form on the implants a nano-relief surface, but also drastically reduce on this surface the concentration of toxic elements that are initially present in the implant material VT6.0.
