The Borofuse process is a unique and proprietary process whereby hardness can be significantly increased.
In the case of ferrous alloys, this can be typically in the range of 1500-1700 KHN. This hardness is compatible to that of cobalt bonded tungsten carbide (typically Ra 90), a hardness which is significantly higher than that achievable by case hardening processes such as carburizing (about Rc62=775 KHN) or nitriding (about 1000 KHN).
The process is suitable for virtually all forms & shapes of ferrous, nickel, and cobalt alloys, as well as refractory metals and cobalt & nickel bonded tungstens and titanium carbides.
Other benefits include greatly improving the resistance to adhesive or abrasive wear, the elimination of galling and a typical 5-10 times increase in service lifetime in specific corrosive environments.
Some typical applications include:
- Exhaust Nozzles within Gas Turbine Engines
- Fuel Pump components within Gas Turbine Engines
Oil & Gas
- Linear Actuators
- Ball Valves
- Valve Seats
- Sprue Bushings
- Moulds & Granulator Screens
- Seaming Rollers
