Boriding




Production

Boriding is a thermochemical surface treatment for ferrous metals where boron diffuses into the metal surface to provide an extremely hard and wear-resistant surface layer. The method is suitable for components which are exposed to extreme adhesive wear or abrasion and where other treatments (e.g., nitriding, flame, induction, and case hardening) reach their limits. All ferrous materials as well as numerous high alloy steels are suitable for boriding.

Examples of application

  • Suitable for iron materials / ferrous metals, high alloy steels or other alloys (e.g., Ni alloys)
  • Thickness of the diffusion layer from 10 to 300 µ
  • Surface hardness between 1600 and 2000 HV, i.e., three times as high as for untreated materials and twice as high as after nitriding or hardening
  • Higher corrosion resistance than in the case of untreated materials
  • Clear reduction of the tendency to cold welding as compared with other untreated materials
  • Important basic material properties such as thermal conductivity, electrical conductivity, thermal stability, and elasticity remain unchanged

Fields of application
