What is the difference between nitriding and nitrocarburizing?
Nitriding is used on ferrous, titanium, aluminum, and molybdenum alloys, and most commonly on low-carbon, low-alloy steels. Nitrocarburizing is only used on ferrous alloys. They improve surface properties of metal components and tools such as scuff and corrosion resistance, and increase the fatigue strength.
What is gas nitrocarburizing?
Gas nitrocarburizing is a variation of the nitriding process. It is a thermo-chemical diffusion process where nitrogen, carbon, and to a very small degree, oxygen atoms diffuse into the surface of the steel, forming a compound layer at the surface, and a diffusion layer.
Why is carbonitriding important?
Benefits of Carbonitriding The diffusion of both carbon and nitrogen increases the hardenability of plain carbon and low alloy steels, and creates a harder case than carburising. The carbonitriding process is particularly suited for clean mass production of small components.
What is salt bath Nitrocarburizing?
Fluidised bed/salt bath nitriding/nitrocarburising is a process used to improve the wear resistance, fatigue strength and, when combined with post oxidation through oxidative cooling, improved corrosion resistance on products made from steel, cast iron and sintered iron.
What is Tufftride?
The Tufftride® process of Durferrit is a surface heat treatment Salt Bath Nitrocarburising treatment carried out at around 580°C for relatively short times (30 minutes to 3 hours) which produces a hard wear resistant surface on many steels.
What is salt bath nitriding?
The hallmark of salt bath nitriding is the bath of molten salt (usually cyanide or other salts) into which parts are submerged. The method features the transfer via diffusion of carbon and nitrogen from the molten salt to the surface of a steel part.
Is Melonite a good finish?
Melonite is basically salt bath ferritic nitrocarburizing, also known as liquid nitrocarburizing. Melonite is also called Tenifer by Glock. It is the finish we use on all our black slides and its durability is unparalleled by any black finish we have used.
What can Melonite be used for in steel treatment?
Melonite ® is a thermochemical treatment for improving the surface properties of steel parts. It exhibits predictable and repeatable results in the treating of low and medium carbon steels, alloy steels, stainless and austenitic steels, tool and die steels, cast and sintered iron.
What kind of nitrocarburizing do Heckler and Koch use?
Heckler & Koch use a nitrocarburizing process they refer to as Hostile Environment. Pistol manufacturer Caracal International L.L.C. uses ferritic nitrocarburizing for finishing parts such as barrels and slides with the plasma-based post oxidation process (PlasOx).
Which is the best description of ferritic nitroburizing?
Ferritic nitrocarburizing. Ferritic nitrocarburizing, also known by the proprietary names Tennifer/ Tenifer and Melonite, is a range of proprietary case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures during a salt bath.
How long does it take to clean ferritic nitrocarburizing process?
The parts are first cleaned, usually with a vapor degreasing process, and then nitrocarburized around 570 °C (1,058 °F), with a process time that ranges from one to four hours. The actual gas mixtures are proprietary, but they usually contain ammonia and an endothermic gas.
