TBC Solutions for Aero Engines

In the aerospace industry, aero engines operate under intense thermal, mechanical, and chemical stress. With rising efficiency and sustainability goals, aircraft manufacturers and MRO providers are increasingly relying on Thermal Barrier Coatings (TBCs) to extend component life and reduce fuel consumption.

This demanding environment introduces several key challenges:

tbc-aero-engine
  • Thermal Cycling & Fatigue : Aircraft engines face frequent take-off/landing cycles and rapid power variations, causing repeated heating and cooling. TBCs must resist microcracking, delamination, and stress-induced failure.
  • Erosion & Contamination : Blades and vanes are exposed to particulates (e.g. volcanic ash, sand) and high-velocity gas streams. Erosion and silicate deposition can degrade coating structure, reduce insulation, and trigger early failure.
  • MRO Compatibility : TBCs must not only protect in-flight but also allow for repeatable repair and overhaul cycles, including stripping, welding, recoating, and reassembly.

OUR SOLUTIONS: TBC POWDERS &EB-PVD INGOTS FOR AERO ENGINES 


To meet the extreme thermal cycling, erosion, and contamination challenges of modern aircraft turbines, Saint-Gobain Coating Solutions offers a portfolio of high-purity Yttria-Stabilized Zirconia (YSZ) and others compositions in both thermal spray powders and EB-PVD ingots specifically developed for Thermal Barrier Coatings (TBCs) in aviation applications.

Our materials are engineered to deliver exceptional thermal insulation, resistance to high-frequency thermal cycling, and compatibility with both OEM and MRO repair processes. From HPT blades to combustor liners, our Zirconia-Based Ceramic Materials help protect mission-critical components under the most severe flight conditions.

Our core product families include: 

8% Yttria-Stabilized Zirconia (8YSZ) powder
tbc-aero-yttria

This high-purity 8YSZ grade is the industry reference for aero engine TBCs. It produces dense coatings with outstanding crack resistance and compliance under thermal cycling.

Widely used in ceramic top coats applied over MCrAlY bond coats, it protects mission-critical parts such as:

  • HPT blades and vanes
  • Combustor liners
  • Air sealing segments

The powder offers low thermal conductivity, excellent phase retention, and durability under aggressive thermal cycling typical of flight operations.
