Explain nitriding heat treatment
)
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, aluminium and molybdenum. Typical applications include gears, crankshafts, camshafts, cam … See more The processes are named after the medium used to donate. The three main methods used are: gas nitriding, salt bath nitriding, and plasma nitriding.

Nitriding is one of the heat treatment processes in which the nitrogen spreads over the surface of the metal to form its layer on the surface of the metal. Thus, nitriding is one of the part of the case hardening. It is used mostly in case of steels that contain low carbon content.

Being able to change the hardness, toughness, and strength of a metal while keeping its chemical composition intact and virtually unaltered is a great way to tailor a metal to the needs of the environment and the demands of the job in which the metal is being …
WebNitriding is a heat treatment performed to harden the surface by introducing nitrogen into the surface of steel. If the steel alloy includes aluminum, chrome, and molybdenum, it enhances nitriding and hardness can be obtained. A representative nitride steel is SACM645 (Aluminum chromium molybdenum steel). WebNo other heat treatment is required after nitriding. But, nitriding is an expensive process: 1. As low temperatures are used in nitriding, much more time is required to develop the requisite case depth. It takes 48 to 96 hours of nitriding to develop a case depth of around 1 mm. 2. Expensive gas ammonia is used in nitriding.
