Extend the life of steel and special metals

Outstanding Wear Resistance

The BOROFUSE® boronizing process is carried out on a wide range of ferrous (metals containing iron) and non-ferrous materials to achieve a hardness many times higher than any other surface hardening process. Boriding of any nickel, iron or cobalt base alloy is possible. The most common materials are typically Inconel 718, Stellite 3, Tungsten Carbide (nickel or cobalt), and 1095 steel. However, a large number of other alloys have been successfully borided. MDC’s BOROFUSE process is an economical solution to a variety of demanding wear problems. Do you have a question about whether a particular material is suitable for our superior boronizing process? Please drop us a line. We’re here to help.

Nickel based alloys are excellent substrates for boriding.  For Inconel 718 the inherent mechanical, corrosion and high temperature properties are perfectly compatible with the BOROFUSE  process resulting in dramatic increases in the value and life of a component while maintaining the original tensile, hardness and corrosion properties. During the boriding process there are minimal changes to the microstructure of the base material as well as small changes to the dimensions. All things considered, the final properties of a BOROFUSE processed Inconel and nickel based alloys are perfectly suited for high wear demanding applications.

CEMENTED CARBIDE

WE'VE WORKED WITH...

Tungsten Carbide (Cobalt Binder)
Tungsten Carbide (Nickel Binder)

Tungsten carbide with a nickel or cobalt binder has a very high hardness. The strength results from the extremely hard tungsten carbide particles bonded together using cobalt or nickel alloys. Specific properties can be achieved by varying the percent of binder, type and the particle size. Lowering the binder percent results in a trade-off between hardness and brittleness; boriding cemented carbide allows the best of both.  By boriding a higher percent binder we can maintain tough core properties but increases the binder hardness at the surface up to the hardness of the carbide particles.  This dramatically increases the wear resistance without increasing the brittleness of the core. BOROFUSE enables the  use of more commercially available tungsten carbide while attaining lower wear rates than more expensive alternatives.

An extremely wide range of iron based alloys are viable substrates for the BOROFUSE process. Iron based materials were some of the first alloys that were commercially borided. Air hardened steels have been very successfully borided resulting in the very hard surface with a fully hardened substrate. Borided iron based alloys can have excellent friction and wear improvement over un-borided components, which can lead to extensive improvements in part life.

COBALT BASED ALLOYS

WE'VE WORKED WITH...

Ultimet Cobalt Based (UNS R31233)
Haynes 25 (Stellite 25) (UNS R30605)
Stellite 3 (UNS R30103)
Stellite 31 (UNS R30031)
Stellite 6 (UNS R30006)
Stellite 6B (UNS R30016)

Boriding cobalt based alloys is similar to nickel based alloys. The substrate maintains the core properties while selectively hardening the surface. While many cobalt based alloys have excellent wear and erosion properties, which can be significantly improved through boriding to meet the requirements for the harshest environments. Cobalt based alloys are also very stable through the thermochemical process.
