Nitriding. A modern computerised nitriding furnace. 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 .
Ferritic nitrocarburizing or FNC, also known by the proprietary names Tenifer, Tufftride and Melonite as well as ARCOR, [Note 1] [1] is a range of proprietary case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub- critical temperatures during a salt bath. Other methods of ferritic nitrocarburizing include gaseous ...
Diamond-like carbon ( DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.
Quench polish quench. Quench polish quench ( QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1] Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). [2]
Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. Nitrides of heavier members from group 11 and 12 are less stable than copper nitride (Cu 3 N) and zinc nitride (Zn 3 N 2): dry silver nitride (Ag 3 N) is a contact explosive which may detonate from the slightest touch, even a falling water droplet.

Infobox references. Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si. 3N. 4 ( Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″ Silicon nitride ″ commonly refers to this specific composition.
