WebSamples made of AISI 4140 steel were first plasma nitrided and then coated with a hydrogen-free hard carbon coating. Results of the rolling tests, performed under various conditions, show that by proper treatment of the substrate material not only the sliding but also the rolling properties of ta-C coated low alloy steel can be greatly improved. WebThe ion nitriding process is carried out in a vacuum vessel where a high-voltage electrical charge forms plasma, causing nitrogen ions to accelerate and impinge on the metal. When the nitrogen ions bombard the part they …

Percentage increase in the nitrogen diffusion depth of the material ion nitrided using the “active screen” method in relation to cathodic nitriding with different duration of the process (5 h, 8 h, 11 h, 14 h ... Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state. Meer weergeven Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-alloy steels. They are also used on titanium Meer weergeven The processes are named after the medium used to donate. The three main methods used are: gas nitriding, salt bath nitriding, and plasma nitriding.
