Abstract

Laser remelting of thermal spray coating of NiCrBSi+TiN powders on surface of TC4 alloy was performed, and its microstructure was studied by means of SEM and TEM. The experimental results show that macroscopic defects in the thermal spray coatings are eliminated after laser remelting. The phases of the coatings are composed of (Cr-Ni-Fe), TiNi, NiB, Cr₂Ti, Ti₂Ni. Cr-rich phase and Ni-rich phase are dominant in the clad zone, and the rod-like phase in the dilution zone is Ti₂Ni-type intermetallics.
