Autogenous powder spraying

Typical Spray Coats

  • Self-flowing alloys (fusing)
  • Ni/Fe/Mo base materials
  • Ceramics/cermets
  • Wear-resistant layers (Ni-graphite)
  • Plastics (e.g. Rilsan, polyamide)
  • Material form: powder
  • Combustion of acetylene with oxygen
  • Flame temperature: 2,000-3,000 °C
  • Particle speed: 50-100 m/s

After-treatment by fusing (“fusing”)

  • Heat part to 1,000°C to 1,200°C
  • Provides a homogeneous coating structure (“no” porosity)
  • Adhesion principle is based on diffusion
  • Suitable for all types of heavy loads (impact resistant)
