| titleOfInvention | Yb-modified CMAS-resistant composite-structure thermal barrier coating and preparation method thereof |
| abstract | The invention discloses a Yb modified CMAS (China Mobile alliance) prevention composite structure thermal barrier coating and a preparation method thereof.A CMAS corrosion prevention layer adopts Yb modified rare earth zirconate to form a compact layered structure and can react with CMAS at high temperature to form a compact barrier layer to prevent molten CMAS from permeating into the thermal barrier coating; the first heat insulation layer adopts Yb modified rare earth zirconate to form a columnar structure, so that enough heat insulation performance and high strain tolerance can be provided for the thermal barrier coating, the thermal shock performance of the thermal barrier coating is improved, and the service life of the thermal barrier coating is prolonged; the CMAS corrosion-resistant layer and the first heat-insulating layer are made of materials composed of the same elements, so that the thermal mismatching stress between the two layers can be relieved, and the bonding strength of the two layers is improved. The thermal barrier coating provided by the invention has the characteristics of low thermal conductivity, stable phase, high bonding strength and strong sintering resistance, and has the advantages of long service life under a high-temperature service condition, high bonding strength between double-layer ceramics and high bonding strength between a ceramic layer and a metal bonding layer. |
