A few-layered Ti3C2 MXene-coated Ti-6Al-4V composite powder was developed with uniform dispersion, high purity, and good thermal stability. The composite showed increased yield strength and thermal conductivity due to the retention and uniform distribution of MXene.
A few-layered Ti3C2 MXene-coated Ti-6Al-4V composite powder was developed via powder surface modification by using fluidization technology. The obtained MXene coating demonstrated the advantages of uniform dispersion, high purity and good thermal stability. Also, the coating enabled the massive retention and uniform distribution of MXene in the sintered composite. Compared to the bare Ti-6Al-4V alloy, the yield strength of MXene/Ti-6Al-4V composite was increased from 895 to 1297 MPa, while maintaining the similar strain. The thermal conductivity of composite was approximately four-fold compared to that of Ti-6Al-4V alloy, which is attributed to the intrinsically high thermal conductivity and the uniform distribution characteristics of the remained Ti(3)C(2 )MXene in the composite.
