The Effect of Zirconium on the Formation Processes of Layered Composition Materials of Titanium–Aluminum and Durability of Aluminum Clutch with Titanium

Resumo

The processes of wetting and spreading of zirconium-doped aluminum over titanium were studied under the conditions of the formation of layered aluminum-titanium composite materials with the activation of the surface of titanium with flux based on K₂TiF₆ salt. It is established that zirconium, owing to an increase in viscosity and a decrease in the fluidity of the melt, reduces the area of ​​spreading of aluminum over titanium. Doping the intermetallic layer between aluminum and titanium with zirconium leads to an increase in the adhesion strength of the composite layers. The maximum values ​​of adhesion strength are observed at a process temperature of 950°C and a zirconium concentration of 0.25%.
