Boronizing - Titankote™B
Boronizing (also known as boriding) is a thermo-chemical surface hardening process in which boron atoms are diffused into the surface of a work piece to form complex borides (i.e. – FeB/FeB2) with the base metal. There is no mechanical interface between the complex borides and the substrate as this is a true diffusion process. The resulting case layer has a hard, slippery surface capable of performing at higher temperatures than most surface treatments. Practically any ferrous material can be boronized, as well as many Ni, Ti & Co alloys. However, it is important to note, the higher the content of alloy elements, the slower the diffusion rate.
We are pleased to offer the boronizing process under the proprietary name Titankote™ B.

Features/Benefits of Titankote™B (Boronizing) Process:
- High hardness (1600-1900 HV in ferrous materials)
- High resistance to temperature (approx. 1200 ° F)
- Increases resistance to acids (especially Hydrochloric acid)
- Reduced coefficient of friction (0.4)
- Boronized layer can be polished to a high finish
- Reduced tendency to cold weld
- Suitable for a broad range of materials
- Boronized layer can be selectively applied
- Surface treatment can be uniformly applied to irregular shapes
- Heat treatable materials can be fully hardened after boronizing
- Uniform case depths of diffusion layers are controllable
Due to wear/performance benefits provided by the boronized layer, combined with the broad range of compatible substrates and the cost-effective nature of the process, boronizing is used successfully for general wear resistance of carbon steel components. Additionally, due to its temperature and wear resistance, boronizing is also a good choice for certain tooling applications.
