Titanium, gold, platinum and silver alloys
Technical characteristics
Production of titanium alloys is carried out in crucible induction furnaces. Due to the significant difference in melting temperature between titanium and noble metals, powder metallurgy techniques are used to produce titanium alloys with gold or silver. Naturally, the amount of additional components used for alloying titanium alloys is not limited to the noble metals; it all depends on the specific application field.

Ion implantation - technology of introducing atoms of alloying elements, e.g. gold, into surface layer of band or foil by means of high energy beam bombardment (10-2000 KeV) applied to create semiconductors with required properties, donor or acceptor zones and low-resistance contacts. Ion implantation is also used to alloy metal to impart hardness and wear resistance to the surface layer.
Thermal diffusion is a technology of introducing atoms of alloying elements into the alloy under the influence of temperature gradient. This phenomenon was discovered in 1856 by the German chemist K. Ludwig and studied by the Swiss scientist S. Saure.
Titanium and platinum alloys have found their application in jewelry technology. The main argument in favor of using this system is the increase in strength and ductility of platinum due to the addition of titanium iodide. The situation is similar with the use of titanium and silver compounds in alloys as an alloying additive. That is, the above Ti-Ag system is not widespread, but plays an important role as an element of solder for vacuum brazing.
In the domestic industry the most common are alloys of titanium with vanadium or molybdenum. the above alloying elements allow obtaining excellent properties and at the same time at relatively low production cost. As for such exotic alloys as titanium and gold, it is practically impossible to meet them in practice. From a theoretical point of view, it can be assumed that this system has an increased resistance to corrosion in a certain aggressive environment.
