The process is carried out by introducing <strong> oxygen at a temperature <\/strong> up to 570 \u00b0C.\u00a0<br>\n\u00a0<br>\nNitriding and nitrocarburising create a thin compound layer of only a few micrometres on the workpiece. During oxidising, the free iron molecules as well as the iron nitrides in this compound layer react with the introduced oxygen to produce stable iron oxide, which then accumulates as a thin oxide layer of no more than 3 \u00b5m on the surface of the component. This layer is extremely resistant to chemicals and, together with the <strong>compound layer, it gives the workpiece high corrosion resistance <\/strong>and other important properties.\u00a0<br>\n\u00a0<br>\nIf post-oxidation is planned, it forms the final step of the process, immediately after nitriding. The surface <strong>must not be processed <\/strong>further after oxidising, as this would remove the protective layer. The formation of a compound layer during nitriding is a prerequisite for successful, long-lasting oxidation. This is because the hardened compound layer consists mainly of iron nitride, while the underlying diffusion layer contains ferrite, to which the oxide layer adheres much less strongly.<\/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_792ff9f15634bbbd2b805c97481d3a09\" class=\"verfahren-text toc\" data-toctitle=\"Geeignete Werkstoffe\" 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\">Suitable materials<\/h2>\r\n                                \r\n                <\/div>\r\n            \r\n                <div class=\"content-box texteditor\" style=\"\">                    \r\n                    <p><p>Since oxidising is a post-treatment of nitrided workpieces, all metals that can be nitrided are suitable for this process.
