As a result, the post-nitriding oxidation treatment has a net effect of enhancing the corrosion resistance of an already nitrided component. This integrated process (i.e.\u00a0Nitreg\u00ae\u00a0+ ONC\u00ae or\u00a0Nitreg\u00ae-C\u00a0+ ONC\u00ae) simultaneously enhances corrosion and wear resistance of steel, while giving the surface an attractive dark or black appearance, expressly desired by many customers.<\/p>\n<p>ONC\u00ae is a clean technology that in many instances can replace chrome plating and salt bath nitriding with their inherent problems of pollution and cost. Depending on the type of steel, parts treated with the Nitreg\u00ae + ONC processes can easily pass well over 200 hours of salt-spray test per ASTM B117 before the first corrosion spot appears.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>ONC\u00ae Advantage<\/strong><\/p>\n<ul>\n<li>Builds on the benefits of <u>Nitreg<\/u> and <u>Nitreg-C<\/u><\/li>\n<li>Improves corrosion resistance<\/li>\n<li>Imparts an attractive black surface finish<\/li>\n<li>Enhances inherent wear resistance<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>In-process Post-Nitriding\/Nitrocarburizing Oxidation<\/p>\n","protected":false},"featured_media":2098,"comment_status":"open","ping_status":"closed","template":"","meta":{"spay_email":""},"new_scheduled_revision":null,"save_as_revision":null,"_links":{"self":[{"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/product\/832"}],"collection":[{"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/comments?post=832"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/media\/2098"}],"wp:attachment":[{"href":"https:\/\/nitrex.gxinteractive.com\/en\/wp-json\/wp\/v2\/media?parent=832"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
