Morphology of TiC Reinforced Ni-Cr-Mo Composite Coatings Prepared by CO₂ Laser

Abstract:

Carbon dioxide (CO₂) laser was applied to fabricate TiC reinforced composite coatings. Different microstructures of ceramic phases were observed by SEM. The main phases of coatings were detected by XRD, while the individual one was examined by electron probe X-ray microanalysis .The effect of composition of binder phases on morphology was explained by the ratio of the temperature gradient in front of the liquid/ solid interface to the growth rate.
