CARBONING VS. NITRATION
VIEW THE DIFFERENCES
Carburizing and nitriding are two different heat treatment processes used to improve the surface properties of metals. Carburizing introduces carbon into the surface of the metal, while nitriding introduces nitrogen. Thus, the main difference between the two processes lies in the nature of the element introduced. Carburizing is often used to improve surface hardness and wear resistance, while nitriding is primarily used to increase surface hardness and corrosion resistance.
Carburizing
- High treatment temperature (900-950°C)
- Larger layer thickness (0,5-4mm)
- Deformation (finishing or milling required)
- Maximum hardness 63hrc
- Extra heat treatment required (tempering)
- High application speed (0.1-0.2 mm per hour)
- High pressure load with low speeds
Nitrating
- lower treatment temperature (520°C)
- Lower layer thickness (0,1-0,8mm)
- Hardly any distortion
- Hardness depending on the chosen material
e.g. 1.8505 becomes 1050 Hv (70 hrc) & 1.7225 becomes 700Hv - No after treatment
- Low application speed (0.01 mm per hour)
- Low pressure load with relatively high speeds
