Nitriding does affect dimensions, but the changes are minimal.
This minimal dimensional change is due to the controlled low processing temperature used in the nitriding process, which typically ranges from 700 to 1,200°F (371 to 649°C).
This temperature range is chosen to preserve the mechanical properties of the base material and to minimize distortion of the finished parts.
4 key points to consider
1. Nitriding Process Overview
The nitriding process involves introducing nitrogen into the surface layer of a metal, typically steel, to improve its hardness, wear resistance, and other mechanical properties.
The nitrogen is introduced through various methods, including gas nitriding, plasma (ion) nitriding, and vacuum nitriding.
Each of these methods uses a controlled environment to ensure that the nitrogen is evenly distributed and that the dimensional changes are kept to a minimum.
2. Plasma Nitriding
For instance, in plasma nitriding, nitrogen gas is used at low pressures, and an electric field is applied to make the nitrogen reactive.
This process is carried out at temperatures below the critical temperature where significant dimensional changes would occur.
3. Vacuum Nitriding
Similarly, vacuum nitriding is performed at a controlled low temperature to prevent distortion and maintain the mechanical properties of the base material.
4. Minimal Dimensional Changes
The minimal dimensional changes during nitriding are also due to the fact that the process does not involve any melting or significant plastic deformation of the material.
Instead, the nitrogen atoms diffuse into the surface of the metal, forming a hard layer without altering the overall shape or dimensions of the part significantly.
