Oxidation Protection Layer: Thickness 50-200 µm, Porosity <1%

Component Specifications

Definition

The Oxidation Protection Layer is a specialized coating applied to metal components exposed to high-temperature environments. It forms a barrier against oxygen diffusion, preventing oxidation and scaling, thereby extending component life and maintaining mechanical properties.

Working Principle

The layer acts as a diffusion barrier, reducing oxygen permeability to the substrate. It may also form a stable oxide scale that is adherent and non-porous, inhibiting further oxidation.

Materials

Typically composed of alumina (Al2O3), chromia (Cr2O3), or silica (SiO2) based ceramics, sometimes with yttria or rare earth additions for improved adhesion.
