TiN-reinforced high-entropy alloy coating demonstrates excellent performance in improving wear resistance and service life of the coating.
TiN-reinforced high-entropy alloy (HEA) coating has been widely applied in the field of surface strengthening. The isotropy, high modulus, high hardness and excellent chemical stability of TiN combine with the ductility of HEA, so as to significantly optimize the wear resistance and service life of HEA coating. In this work, in-situ TiNreinforced AlCoCrCuNiTi HEA coating was synthesized, and TiN phase had a coherent interface between (Ni, Co) Ti2 phase. Besides, the relationship between reinforcing behavior of TiN and wear resistance of HEA coating was analyzed based on experimental observation and first-principle model.
