The nitriding layer is created.
Workpieces made of ferrous materials exhibit better wear, strength and corrosion properties after nitriding. Determination of the nitriding hardness depth is defined in standard DIN As long as it is thermally stable, the original structure remains unchanged.
NHD – Nitriding Hardness Depth – Curve Measurements
Standaed test method to be used is Vickers in the low-load range. Subsequently, hardness indents are applied from the edge to the workpiece interior at precisely defined distances.
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. 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.
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. Please select Mr Ms.
To satndard general tips First, the core hardness must be determined. Contact us We look forward to hearing from you Your enquiry Support hotline Dealers and demo rooms Newsletter.
The surface of the specimen to be measured must be finely machined.
Then the nitrogen donor is transported to the workpiece surface and adsorbed. Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. To the general tips. In contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon.
