WebPlasma (Ion) Nitriding The main advantages of Plasma Nitriding are the enhancement of Surface Hardness, Fatigue Life, Wear Resistance and Corrosion Resistance of the processed parts. Nitriding of Parts and Tools with Complex Geometry Plasma nitriding is suitable for treating parts and tools with complex shapes and geometries. WebIt takes 48 to 96 hours of nitriding to develop a case depth of around 1 mm. 2. Expensive gas ammonia is used in nitriding. 3. Expensive alloy steels can only be nitrided and are used. Thus, as a case-hardening process, nitriding is more expensive as compared to carburising or carbonitriding.

WebThe process increases the surface hardness of most auste- nitic stainless steels to a level of about 1000– 1200 HV 0.05, which is about five times the original hardness. High compressive stresses are formed on the surface, due to interstitial solution of carbon atoms. All austenitic stain- less steels can be hardened using this pro- cess. 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.
