The nitrogen penetrates the workpiece and forms on its surface a hard compound layer composed of iron nitrides. Located underneath is the diffusion zone. In this zone, nitrogen embeds in the metal matrix of the workpiece, thus increasing its fatigue strength. The highest values can be achieved with nitriding steels.<br \/>\n&nbsp;<br \/>\nNitriding requires temperatures between 500\u00b0C and 580\u00b0C. Treatment times vary between one and one hundred hours. The thickness of the compound layer and the development of the porous zones depend on the temperature and duration of the treatment. To define the nitriding hardness depth (NHD) of the treatment, the limit hardness is used as a reference. This is 50 HV higher than the core hardness of the workpiece.<br \/>\n&nbsp;<br \/>\nThe layer\u2019s resistance to corrosion can be further improved by oxidation. If additional coatings (galvanic or chemical) are planned later on, the workpiece can also be nitrided without a compound layer.<br \/>\n&nbsp;<br \/>\nThe process is different from nitrocarburising, which involves the additional use of carbon.\n<br>\n<br><br \/>\n&nbsp;<\/p>\n<h3>Graphical representation: Structure and functional principle<\/h3>\n<p>&nbsp;<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-1575\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG.png\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG.png 2000w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-300x300.png 300w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-1024x1024.png 1024w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-150x150.png 150w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-768x768.png 768w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-1536x1536.png 1536w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-12x12.png 12w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/nitrieren-aufbau-funktionsweise_ENG-1106x1106.png 1106w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><br \/>\n&nbsp;<br \/>\n<br>\nThe most commonly used nitriding processes are:<\/p>\n<ul>\n<li><a href=\"https:\/\/haertha.de\/verfahren\/salzbadnitrieren\/\">Salt bath nitriding<\/a><\/li>\n<li><a href=\"https:\/\/haertha.de\/verfahren\/gasnitrieren\/\">Gas nitriding\u00a0<\/a><\/li>\n<li><a href=\"https:\/\/haertha.de\/verfahren\/plasmanitrieren\/\">Plasma nitriding<\/a><\/li>\n<\/ul>\n<p class=\" translation-block\">Each of these processes also permits partial nitriding.

With the latter, the surface of the material may become brittle instead of hard. For this reason, low- or non-alloy steels are nitrocarburised instead. This process produces a compound layer that improves protection against wear and corrosion. This compound layer can also be subjected to post-oxidation. That creates another thin oxide layer with a thickness between 1 \u2013 3 \u00b5m and provides even greater protection.<\/p>\n<p><br>\nIn contrast, elements such as molybdenum, titanium, chromium, or aluminium contained in alloy steels produce particularly hard nitrides when reacting with nitrogen.
