Microstructure and Thermal Shock Resistance of Laser Remelting ZrO₂-8wt%Y₂O₃ Thermal Barrier Coating Fabricated by Plasma Spraying

Abstract:

The yttrium stabilized zirconia (YSZ) thermal barrier coatings (TBCs) were fabricated by plasma spraying on the surface of H13 hot work die steel and then were remelted by a transverse flow CO₂ laser. The phase compositions, microstructure and thermal shock resistance of the as-sprayed and laser remelted coatings were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal shock tests. The results showed that the quality of laser remelted coating was improved obviously. Also, the thermal shock resistance of the TBCs was improved dramatically by laser surface remelting.
