Ultra-Thin Gold Coatings for Extreme Demands

Ultra-thin gold nanolayer coating for demanding environments

BLOOH Solution develops ruthenium-stabilized, ultra-thin gold coatings that resist corrosion, oxidation and thermal stress while preserving high electrical conductivity. Compared to electroplating, our magnetron-sputtered layers achieve uniform thickness on complex microstructures and remain chemically inert and biocompatible in saline and oxidative environments.

Production & Process Advantages

  • • Magnetron PVD + Ru pre-treatment + nanoscale smoothing for adhesion, coverage & durability
  • • Uniform nanolayers on complex geometries; minimizes micropores & performance loss
  • • Chemically inert, biocompatible surfaces that maintain conductivity under saline/oxidative stress

Validated In-House Tests

  • • Thermal cycling: −80 °C to +700 °C
  • • Salt spray exposure: >1,000 hours (ASTM B117)
  • • Long-term mechanical stress & scratch resistance
  • • Current load testing under varying AC/DC conditions

Core Technologies

  • • Ruthenium-stabilized interlayers to prevent delamination
  • • Precision layer tuning for high-frequency contacts
  • • Nanoporosity control for optimized insulation & conductivity
  • • Biostable surfaces for long-term clinical applications
