New use and recycling of aluminium and titanium for long run protection of steel in special biocorrosive places.
Project aim is the “ennoblement” of light alloy swarfs, for production of new materials and thready composite structures having a steel core and external shell in light alloy or intermetallic, to use in highly corrosive conditions, such as sea environment or zootechnics. At present, light alloys swarfs such as alluminium and titanium, are scarcely recyclable.
In this field, the aim is to use them as they are after mechanical working, through an advanced process of hot co-extrusion in which a steel preshaped central core obtained throught traditional drawing, is adhered to an aluminium or aluminium and titanium layer, so as to be able to give excellent mechanical properties and durability.
Materials obtained in such way, could support commercial galvanized wire , working in all those applications where a higher corrosion resistance is requested (in the presence of sea water and ammonia).
