Workpieces made of ferrous materials exhibit better wear, strength and corrosion properties after nitriding. To the general tips.

Then the nitrogen donor is transported to the workpiece surface and adsorbed. We take standards compliance and data protection extremely seriously, and therefore urge you to accept our privacy policy. To the general tips First, the core hardness must be determined.

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.

srandard Subsequently, hardness indents are applied from the edge to the workpiece interior at precisely defined distances. This results in a release of nitrogen atoms at the specimen surface. Close Enter search term As long as it is thermally stable, the original structure remains unchanged.

Further information can be found in our privacy policy. The increase in nitrogen content also leads to an increase in hardness. Please select Mr Ms.

The surface of the specimen to be measured must be finely machined. In contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon. This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained.

Curve measurements NHD – Nitriding Hardness Depth Back to overview Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. The data are not passed on to other recipients.

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 limit.

NHD – Nitriding Hardness Depth – Curve Measurements

Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. The nitriding layer is created. First, the core hardness must be determined. The test method to be used is Vickers in the low-load range.

The nitrogen atoms are absorbed and diffuse further into the workpiece interior. Determination of the nitriding hardness depth is defined in standard DIN All you need to know. Contact us We look forward to hearing from you Your enquiry Support hotline Dealers and sin rooms Newsletter.
