Microstructure and element distribution of laser cladding TiC -reinforced CrTi4-based composite coating with CeO2/Ce2O3

TiCx-reinforced CrTi4-based composite coating was successfully prepared by laser cladding technology with coaxial Ti6Al4V/NiCr-Cr3C2/CeO2 mixed powders, and their microstructure and element distribution were studied. The results showed that vacant titanium carbide (TiCx) and solid solution (CrTi4) were synthesised in-situ. The distribution of C was differentiated in the TiCx. Al and V were uniformly distributed in the matrix phase, while Ni and...
