Further information can be found in our privacy policy. Curve measurements NHD – Nitriding Hardness Depth Back to overview Like case hardening, nitriding is one of the thermochemical diffusion treatment processes.

The surface of the specimen to be measured must be finely machined. Stanrard test method to be used is Vickers in the low-load range. The nitriding layer is created.

Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. Workpieces made of ferrous materials exhibit better wear, strength and corrosion properties after nitriding.


To the general tips First, the core hardness must be determined. After you submit the contact form, the above-mentioned data will be processed by the party responsible for data protection for the purpose of processing your request on the basis of your consent given by submitting the form.

As long as it is thermally stable, the original structure remains unchanged. We take standards compliance and data protection extremely seriously, and therefore urge you to accept our privacy policy.

Determination of the nitriding hardness depth is defined in standard DIN First, the core hardness must be determined. This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained. In contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon. To the general tips.

The increase in nitrogen content also leads to an increase in hardness. Unless you opt out, the data will be further processed on the same legal basis for the purpose of direct marketing, which is compatible with the original purpose of processing. Then the nitrogen donor is transported to the workpiece surface and adsorbed.


NHD – Nitriding Hardness Depth – Curve Measurements

Please select Mr Ms. The nitriding hardness depth is derived from the curve representing the hardness over distance from the surface by measuring the distance from the surface to the calculated hardness stwndard.

By using the website, you agree. The data are not passed on to other recipients.

Subsequently, hardness indents are applied from the edge to the workpiece interior at precisely defined distances. The nitrogen atoms are absorbed and diffuse further into the workpiece interior. Close Enter search term This results in a release of nitrogen atoms at the specimen surface.
