BORONIZING

Boronizing is a thermochemical diffusion coating that is effective for wear and corrosion. The hardness is approximately 2000 HV. Components in the oil and gas industry that are subject to sour gas are ideal for the boronizing process.

Boronizing Properties:

  • Extremely high wear resistance (erosion or abrasive wear)
  • Galling resistance
  • High surface hardness (1200-1800 HV for ferrous materials, 2000-2800 HV for nickel-based alloys)
  • Boride layer depths can range from 0.0005″ to 0.015″ deep depending on base material and processing parameters selected.
  • High-temperature resistance with up to 1200F service temperature possible with no adverse effects or degradation of the boride layer
  • Increased corrosion resistance to acids
  • Reduced coefficient of friction
  • Wide range of materials possible for treatment
  • Able to be combined with other heat treatment processes such as carburizing, hardening, induction hardening, austempering to develop deeper case depths and improved core properties below boride layer
  • Able to be selectively applied

Boronizing Applications:

  • Coal Mining
  • Coal Fire Plants
  • Wire Ties
  • Steam Turbine
  • Fracking Components
  • Extrusion Tooling
  • Agricultural Rock Guards
