During this process, nitrogen penetrates the material and forms nitrides. Plasma nitriding and plasma nitrocarburising deliver reliably reproducible outcomes and are superior to other nitriding processes - especially in terms of environmental protection and energy consumption. The process requires no toxic gases, and the energy consumption is reduced substantially.<\/p>\n<p>This is partially because the hardening process is carried out at low temperatures between 350 and 600\u00b0C. Warping of the workpieces is also reduced to a minimum, eliminating the need for costly rework, and thus delivering additional cost savings.<\/p>\n<p>Furthermore, plasma nitriding considerably improves a number of workpiece properties, such as service life, corrosion protection, and resistance to fatigue and wear. A partial treatment is also unproblematic. The process is also suitable for subsequent physical and chemical vapour deposition with individual hardness properties, because if necessary a diffusion layer can be created without a compound layer on the surface of the workpiece.<\/p>\n<p>The process is also known by the names of ionitriding, pulse plasma nitriding, cold nitriding, or plasma hardening.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1656\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-1024x682.png\" alt=\"\" width=\"1024\" height=\"682\" srcset=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-1024x682.png 1024w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-300x200.png 300w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-768x512.png 768w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-1536x1024.png 1536w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103-1106x737.png 1106w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1005103.png 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p class=\" translation-block\"><span class=\"block\" style=\"color: #ffffff;background-color: #6ab651;padding: 3rem\"><span style=\"font-weight: 400\">INFO: HLX-1 \u2013 process for special surface protection<br>\nHLX-1 is defined as a diffusion process that specifically treats the surfaces of components and tools.

An electric field is applied during the process. The workpieces act as the cathode, and the furnace wall is the anode. The added mixture of gas is ionised by the electric field and it envelops the workpieces. The process creates nitrogen-rich nitrides, which disintegrate and enrich the surface with nitrogen.\n<br>\n\u00a0<br>\nThe surface is activated, and the workpieces are heated. On steels such as stainless steel, the passive layers detach. Generally speaking, the surface receives fine cleaning, because the process sputters off impurity atoms.<br>\n\u00a0<br>\nThe treatment temperature depends on the material type and the desired nitriding hardness depth. The subsequent dwell time ranges between 12 and 50 hours. To equalise the pressure when the treatment is complete, the furnace is flooded with gas. The workpieces cool down.<br>\n\u00a0<br>\n<img loading=\"lazy\" class=\"alignnone size-large wp-image-1652\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/plasma-1024x693.png\" alt=\"\" width=\"1024\" height=\"693\"><\/p>\n<p>&nbsp;<\/p>\n<\/p>\r\n                    <div class=\"acf-innerblocks-container\"><\/div>\r\n                    \r\n                    <style>\r\n                        .sonder-zeichen{\r\n                            display: flex;\r\n                            flex-direction: row;\r\n                            gap: 15px;\r\n                        }\r\n                        .zeichen{\r\n                            color: #C9C9C9;\r\n                            position: relative;\r\n                            line-height: 66px;\r\n                            font-size: clamp(2.75rem, 1.9766rem + 2.1484vw, 4.125rem);\r\n                        }\r\n                    <\/style>\r\n                    \r\n                <\/div>\r\n            <\/div>\r\n        <\/div>\r\n    <\/div>\r\n<\/div>\r\n\r\n\r\n\r\n\r\n\n\n\r\n<div id=\"verfahren-text-block_b6ae61985fb86636ada8d4f16cabc066\" class=\"verfahren-text toc\" data-toctitle=\"Anwendungsbereiche\" style=\"\">\r\n    <div class=\"row\">\r\n        <div class=\"col-12\">\r\n            <div class=\"content-wrapper\" >\r\n\r\n                            <div class=\"box\">\r\n                                            <div class=\"nummber\"> \r\n                            \r\n                        <\/div>\r\n                        \r\n                                            <h2 class=\"headline\">the process and its advantages\r\n<\/h2>\r\n                                \r\n                <\/div>\r\n            \r\n                <div class=\"content-box texteditor\" style=\"\">                    \r\n                    <p><p class=\" translation-block\">Plasma nitriding ranks among the most flexible and best <a href=\"https:\/\/haertha.de\/en\/verfahren\/nitrieren\/\" target=\"_self\">nitriding processes<\/a>.

The edge distance having a core hardness of +50 HV is considered to be the characteristic value of the nitriding hardness depth (NHD). This is up to 0.6 mm for non-alloy and low-alloy steels and up to 0.10 \/ 0.15 mm for high-alloy steels and stainless steel. Influencing factors are the steel used, along with the duration and the temperature of the treatment.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1578\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG.png\" alt=\"\" width=\"1024\" height=\"1024\" srcset=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG.png 2000w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-300x300.png 300w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-1024x1024.png 1024w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-150x150.png 150w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-768x768.png 768w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-1536x1536.png 1536w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-12x12.png 12w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/03\/plasmanitrieren-nitrierschicht_ENG-1106x1106.png 1106w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>There are variations and enhancements of plasma nitriding, and their use depends on the requirements:<\/p>\n<ul>\n<li>Plasma nitrocarburising: for particularly thick compound layers<\/li>\n<li>Post-oxidation: further increases corrosion protection on low- and medium-alloy materials<\/li>\n<\/ul>\n<\/p>\r\n                    <div class=\"acf-innerblocks-container\"><\/div>\r\n                    \r\n                    <style>\r\n                        .sonder-zeichen{\r\n                            display: flex;\r\n                            flex-direction: row;\r\n                            gap: 15px;\r\n                        }\r\n                        .zeichen{\r\n                            color: #C9C9C9;\r\n                            position: relative;\r\n                            line-height: 66px;\r\n                            font-size: clamp(2.75rem, 1.9766rem + 2.1484vw, 4.125rem);\r\n                        }\r\n                    <\/style>\r\n                    \r\n                <\/div>\r\n            <\/div>\r\n        <\/div>\r\n    <\/div>\r\n<\/div>\r\n\r\n\r\n\r\n\r\n\n\n\r\n<div id=\"verfahren-text-block_85a1036be5cd79975ae30bcd18d776ed\" class=\"verfahren-text toc\" data-toctitle=\"Nitrierbare St\u00e4hle und Behandlungsergebnisse nach dem Plasmanitrieren\" style=\"\">\r\n    <div class=\"row\">\r\n        <div class=\"col-12\">\r\n            <div class=\"content-wrapper\" >\r\n\r\n                            <div class=\"box\">\r\n                                            <div class=\"nummber\"> \r\n                            \r\n                        <\/div>\r\n                        \r\n                                            <h2 class=\"headline\">Nitridable steels and treatment outcomes after plasma nitriding\r\n<\/h2>\r\n                                \r\n                <\/div>\r\n            \r\n                <div class=\"content-box texteditor\" style=\"\">                    \r\n                    <p><p>The following results illustrate the effect of plasma nitriding on frequently used materials.
