The Process
Basic Steps for Liquid Nitriding:
- Degreasing/Rinsing
- Preheating
- Nitro carburizing
- Oxidizing
- Cooling/Cleaning
- Mechanical Polishing
- Permeating
Advantages:
Liquid Nitriding Vs Carburizing
- Low distortion due to lower treatment temperature.
- No need for further machining operations.
- Superior adhesive wear resistance thanks to the ceramic characteristics of the surface.
- Hot strength up to 400°C.
Liquid Nitriding Vs Chrome /Ni Plating
- Excellent corrosion protection in alkaline or neutral environment.
- Superior adhesive wear resistance thanks to the ceramic characteristics of the surface.
- No peeling or flaking since the layer is formed directly from the base material.
- No micro cracks.
- No need for grinding operation after treatment.
- Low coefficient of friction
- Higher environmental favourability; no hex chrome exposure.
Liquid Nitriding Vs Nirto-Carburizing
- Superior corrosion and wear resistance in high volume production.
- Low distortion thanks to the quick and very constant heat transfer by the liquid medium.
- Excellent reproducibility and constancy of the treatment results.
- Very robust process; less sensitive to surface contaminants.
- Easy to control because only a few parameters have to be monitored.
- Shortest cycle times as LIQUID NITRIDING offers the highest nitrogen potential,
- Meets the environmental legislation and standards without problems.
