NITRIDING Meaning and
Definition
-
Nitriding is a surface hardening process which involves the diffusion of nitrogen atoms into the surface layer of a material to improve its hardness, wear resistance, and fatigue strength. It is commonly used for steels and other ferrous alloys.
The nitriding process is typically conducted at elevated temperatures in the range of 500-600 degrees Celsius (932-1112 degrees Fahrenheit) in a nitrogen-rich atmosphere. The material to be treated is first cleaned and then placed in a sealed container, such as a furnace or a specialized vacuum chamber. Ammonia gas (NH3) is introduced into the chamber, and the nitrogen dissociates, releasing nitrogen atoms. These atoms diffuse into the surface layer of the material, forming a hard nitride layer.
The depth of the nitride layer depends on several factors, including the nitriding temperature, time, and the composition of the material. Typically, nitriding depths range from a few microns to several hundred microns.
The resulting nitride layer significantly enhances the surface properties of the material. The diffusion of nitrogen atoms into the crystal lattice of the metal increases its hardness, wear resistance, and resistance to corrosion. Additionally, the presence of the nitride layer improves the material's ability to withstand fatigue and reduces the risk of stress-induced failure.
Nitriding is widely used in various industries, including automotive, aerospace, tooling, and manufacturing, where components such as gears, camshafts, and dies benefit from improved surface hardness and durability.

Etymology of NITRIDING
The word "nitriding" is derived from the combination of two words: "nitro" and "-iding".
The term "nitro" comes from the Latin word "nitrum", which means "saltpeter" or "potassium nitrate" - a substance used in the production of gunpowder. This Latin word was further derived from the Greek word "nitron", which also refers to saltpeter.
The suffix "-iding" is added to the word "nitro" to form "nitriding". This suffix is commonly used in technical and scientific terminology to indicate a process or action. In this case, "nitriding" refers to a process of introducing nitrogen into a material, typically a metal, to improve its hardness, wear resistance, and other desirable properties.
