The processes are named after the medium used to donate. The three main methods used are: gas nitriding, salt bath nitriding, and plasma nitriding. Gas nitriding In gas nitriding the donor is a nitrogen-rich gas, usually ammonia (NH3), which is why it is sometimes known as ammonia nitriding. When ammonia … 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 Examples of easily nitridable steels include the SAE 4100, 4300, 5100, 6100, 8600, 8700, 9300 and 9800 series, UK aircraft … Meer weergeven • Boriding • Carburization • Carbonitriding • Ferritic nitrocarburizing Meer weergeven • "MIL-S-6090A, Military Specification: Process for Steels Used In Aircraft Carburizing and Nitriding".

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.
