The objective of the programme is to obtain a technology for the electrolytic recovery, in molten salts baths, of titanium alloys resulting from industrial machining scrap. This programme is aimed at improving the process of obtaining titanium, starting from alloys containing aluminium and vanadium, nickel and titanium, in order to make it industrially exploitable.

The programme includes the electrolytic recovery in molten salts of titanium from alloys with different degrees of contamination with the setting up of the process that could be used at an industrial scale.

The programme will consist of the following stages.

Design of the cell to be used for experimentation involving:
design of the laboratory electrolytic cell in molten salts;
design of the heating system;
design of the cell's auxiliary plants (power supply, electrodes handling, raw material feeding, product removal);
and design of the control and data acquisition system.

Construction of the cell to be used for experimentation involving:
construction of the cell, with associated frame, heating system and feeding systems;
construction of the cell's auxiliary plants;
and construction of the control and data acquisition systems.

Construction of the new reference electrode.

Experimentation on titanium alloys involving:
experimentation on alloys contaminated with nickel or steel or strongly oxidized;
experimentation on alloys contaminated with steel in the laboratory cell;
experimentation on strongly oxidized alloys in the laboratory cell;
experimentation of a new type of reference electrode in molten salts;
experimentation for the refining of alloys in the pilot plant;
the definition of the cell configuration which is the most suitable for selective deposition;
the definition of the preliminary treatments to be carried out to the product (cleaning, degreasing);
the operative parameters will be established as electrolytic bath temperature and composition, deposition of the current density, applied voltage wave shape and deposit time;
and the definition of the existing relations between process parameters and the different composition of the scrap.

Leaching trials involving: cathodic deposit milling; leaching experimentation; product drying; and analysis of the obtained product.

Melting trials involving: pressure forming and consumable electrodes construction experiments; fusion experiments with a vacuum arc melting with single and double fusion; and characterization of the obtained ingots.

The final stage is data processing.
