| Abstract Scope |
The tailoring power of high-power impulse magnetron sputtering deposition was used to prepare nanocrystalline randomly oriented copper films on titanium powder as substrate. These structures can be implemented as core-shell powders with implications on energy saving and phase formation during sintering for alloy design. The deposition process was performed using physical vapor deposition assisted by vibration. The bimetallic configurations were processed under high heating rate sintering conditions, and the atomic diffusion and reactions were evaluated by electron microscopy and energy dispersive spectroscopy. In this work, the sputtered copper on titanium powders showed an increase in sintering rate compared to unmodified titanium powder and titanium-copper powder mixes. These effects relate to the interfacial reactions between alloying elements influenced by their diffusion lengths and structure. Finally, the sintered specimens were evaluated by hardness testing and electrical conductivity. |
