Component Specifications

Definition
The Surface Passivation Layer is a thin, engineered coating applied to High-Purity Ferrochromium Nitride Alloy Powder particles. It chemically modifies the surface to form a stable, inert barrier that prevents oxidation, reduces reactivity with environmental elements, and maintains the powder's metallurgical properties during storage and processing. This layer is critical for preserving alloy purity and preventing degradation in high-temperature applications.
Working Principle
Works by creating a chemically stable oxide or nitride barrier on the powder surface through controlled deposition or reaction processes. This barrier inhibits further oxidation by blocking oxygen diffusion and prevents surface contamination, ensuring the alloy retains its intended composition and performance characteristics.
Materials
Typically composed of chromium oxide (Cr2O3), aluminum oxide (Al2O3), silicon dioxide (SiO2), or proprietary ceramic compounds. Material selection depends on alloy composition and application requirements.
Technical Parameters
  • Thickness 10-100 nm
  • Adhesion Strength >15 MPa
  • Thermal Stability Up to 800°C
  • Coating Uniformity >95% coverage
  • Particle Size Compatibility 1-100 μm
Standards
ISO 14713, DIN 50942
