Structural Steel Microhardness Improvement by Ion Nitriding

Web7 jul. 2024 · Nitriding requires special steels called ‘Nitralloy’. This is because hardness depends on the formation of very hard compounds of nitrogen and metal such as aluminum, chromium, and vanadium present in the steel. …. This is due to the formation of iron nitrides formed to a considerable depth below the surface of the steel. Web15 mrt. 2024 · In pulse plasma nitriding, parts are loaded into a heated vacuum chamber. The chamber is evacuated to less than 10Pa prior to heating, and several hundred pulsating DC volts are applied between the charge (cathode) and the chamber wall (anode). The process gas in the chamber is then ionized and becomes electrically conducting.

Web15 jul. 2024 · Before the ion nitriding process, all specimens were ground with 220, 800, 1200, and 2000-grade sandpaper. The specimens for the rotating bending fatigue test were fabricated according to the KS B ISO 1143 : 2003 standards. All the specimens were cleaned in an ultrasonic bath containing ethanol for 10 min. 4.2. Ion Nitriding Treatments WebPlasma-assisted ferritic nitrocarburizing is also known as ion nitriding, plasma ion nitriding, or glow-discharge nitriding. The process works to achieve the same result as the salt bath and gaseous process, except the reactivity of the media is not due to the temperature but to the gas ionized state.
