NITRIDING
- Combines excellent wear and lubricating properties with high load carrying capacity and corrosion resistance
- Low temperature process with very little distortion
- Process uses NH3 + a Carbon evolving gas, instead of only NH3 as in conventional gas nitriding
- Nitemper® – a patented Ipsen process using 50% NH3 + 50% Endogas
- Adapted batch and continuous furnace technology
Post Nitriding Properties
- Wear resistance and self-lubrication
- Increase in fatigue strength – a characteristic of the diffusion zone, so it remains even in absence of compound layer
- High corrosion resistance – because of stable Fe-C-N layer
Feature of Nitriding Method
Nitemper® /Nitriding vs. Salt Bath Nitriding
Nitemper/Nitriding
- Cycle time can be as long as required
- Automation is simple
- No disposal issues –gas emission control is easier
- Safer operation
- Batch Furnace so charge loading/unloading is very easy
- Uniform distribution of Nitriding Layer
Salt Bath Nitriding
- Cycle time should be short – cleaning problems
- Automation is difficult
- Salt disposal is a big issue and may be banned in future
- Salt exposes operators to health hazards
- Not uniform distribution of Nitriding Layer
