Overview

Review highlights high-temperature degradation mechanisms in advanced coating systems for aerospace applications, suggesting new material designs.

Key Points

  • This review aims to explore the evolution and degradation mechanisms of thermal and environmental barrier coatings in high-temperature aero-engine applications.
  • Systematic assessment of thermal barrier coatings and environmental barrier coatings from conventional to advanced materials.
  • Comparative analysis of material properties including phase stability and durability at temperatures above 1200 °C.
  • In-depth investigation of degradation mechanisms under various corrosive conditions such as CMAS attack and water-oxygen corrosion.
  • Traditional yttria-stabilized zirconia and silicate systems are evolving into advanced high-entropy and rare-earth-doped coatings.
  • Identified critical durability issues and trade-offs between thermal conductivity and mechanical toughness.
  • Proposed advanced AI-driven models for predicting the lifespan and reliability of next-generation coatings.
