Tribological properties of copper-titanium polymetals obtained by the additive manufacturing

The structure and tribological properties of polymetallic products from Cu-Ti system are investigated. The results of the work show that in the material obtained by successive deposition of titanium and copper filaments on the substrate, a complex structure is formed from a mixture of intermetallic phases with different composition. Friction tests show high tribological properties paired with a steel counterbody. Besides the hardened state associated with the presence of Cu4Ti intermetallic particles, the material of the samples is characterized by the plasticity preservation of the copper matrix, which increases the tribological properties of the finished product.
