Bossard Coating

Tribological dry coating is a system solution for mechanically stressed fastening elements and components, such as screws, nuts and washers. The coating is a non-electrolytically applied, thin layer with integrated lubrication properties and additional corrosion protection.


  • Small friction coefficient scattering
  • Protection against contact corrosion
  • Good sliding properties and thus protection against seizing up
  • No impact on mechanical properties
  • No risk of hydrogen embrittlement
  • Permanent lubrication

Overview of tribological dry coating types:
