What are Thermal Barrier Coatings (TBC) Materials?

Thermal Barrier Coatings (TBC) Materials are specialized protective systems designed to shield components from extreme heat and thermal stresses in high-temperature environments. They are primarily used in industries such as aerospace, power generation, automotive, and industrial manufacturing, where machinery and components operate under intense heat conditions.

Structure of Thermal Barrier Coatings

Thermal barrier coatings are multi-layer systems that consist of the following components:

Metal Substrate:

The underlying metal surface, typically made of superalloys, which provides structural integrity.

Bond Coat:

A metallic layer (e.g., MCrAlY alloys, where M = Nickel, Cobalt) applied to enhance adhesion between the substrate and the ceramic topcoat. The bond coat also acts as a barrier against oxidation and corrosion.

Thermal Insulation Layer (Topcoat):

Made from ceramic materials, primarily yttria-stabilized zirconia (YSZ).

This layer provides excellent thermal insulation, reducing the heat transferred to the substrate.

Optional TGO (Thermally Grown Oxide) Layer:

Forms between the bond coat and the ceramic layer, offering additional protection against oxidation but may influence coating durability over time.

Functions of Thermal Barrier Coatings

Thermal Protection:

Reduce heat transfer to the underlying components, allowing them to operate at higher temperatures safely.

Typical temperature reductions range from 100°C to 300°C, depending on the application.

Oxidation and Corrosion Resistance:

Protect metal substrates from oxidation, corrosion, and chemical degradation in high-temperature environments.
