Titanium is a metal that has been used in various and varied medical applications for about 40 years. Titanium and its alloys have excellent corrosion resistance, in many aqueous media, and assure their excellent biocompatibility. A variety of surface modification processes have been proposed for titanium alloys. The new method of creation biocompatible layers on titanium-aluminium alloys that we want to investigate is based on the use of ascending diffusion effect of solute atoms at sputtering of metal-solvent surface by inert gases ions. Using theoretical calculations technique described, it is possible to choose modes for carrying out ion-plasma processing aimed at getting the effect of ascending diffusion in titanium-aluminium alloy.
