Microstructure and tribological properties of TiCu2Al intermetallic compound coating

► TiCu2Al ternary intermetallic compound coating has been in situ synthesized successfully on pure Ti substrate by laser cladding with aluminum bronze powder. ► Microstructre of the prepared TiCu2Al intermetallic compound coating was systematically analyzed by XRD, SEM and TEM. ► Tribological properties of the TiCu2Al intermetallic compound coating were systematically investigated.
