gas nitriding

Gasbarre Thermal Processing Systems recently commissioned a precision gas nitriding and ferritic nitrocarburizing (FNC) furnace for a commercial heat-treating company located in the Midwest. The furnace is capable of processing workloads that are 48 inches wide x 72 inches long x 40 inches high and weigh up to 7,000 pounds.

Nitriding and Carburizing

2016/10/14Nitriding is carried out at temperatures below the transformation temperature of alloy steels, so that with proper manufacturing techniques, there is little or no distortion. In general, parts to be nitrided are heat treated to the proper strength level, and final machined.

Carbonitriding

Carbonitriding is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip, increasing the hardness and modulus near the surface. Carbonitriding is often

Vacuum Melting Furnace

Vacuum smelting furnace is based on the heating principle that alternating electromagnetic field produces eddy current heat in metal materials. Under the condition of vacuum or protective atmosphere, the melting and casting of steel, special steel, superalloy, precision alloy, non-ferrous metal, rare earth permanent magnet material and other materials are completed.

Gas Nitriding

The principle of nitriding (and ferritic nitrocarburising) of components in a fluidised bed furnace is the same as for gas nitriding /ferritic nitrocarburising. The process gas is ammonia (as well as nitrogen, and any carbon-carrier gas that may be used for ferritic nitrocarburising) and is introduced through the diffuser to achieve fluidisation and nitrided parts.

Vacuum Carburizing Furnace Vacuum Hardening w Oil

The two-chamber furnace, called D type, is a dual-chamber vacuum quench furnace with one chamber for vacuum heat processing and a second chamber for oil quenching or gas quenching. The three-chamber furnace, called T type, provides the same chambers as the D type plus a third pre-heating (and/or pre-oxidation chamber) which increases productivity.

GAS NITRIDING TITANIUM NITREG

Titanium alloys, used mostly in the aerospace and defence industries, can also be successfully gas nitrided for increased wear resistance and to achieve an attractive golden finish. The technology is not widely known since the applications involved are also very specific.

2006/8/23Atmosphere gas is continually withdrawn from the nitriding furnace and passed through a temperature-controlled scrubber containing a water solution of sodium hydroxide (NaOH). Trace amounts of hydrogen cyanide (HCN) formed in the nitriding furnaces are removed in the scrubber thus improving the rate of nitriding.

reducing distortion from nitriding – Sandmark Global

Because of this, nitriding is appropriate only for symmetrical parts such as shafts and gears. This distortion is dependent on the material being used and the geometry of the part. Grinding/Finishing Before Nitriding: All grinding (and finish machining) operations should be carried out to the final dimensions pior to nitriding.

Nitriding — Wikipedia Republished // WIKI 2

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 high-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum. In 2015, nitriding was used to generate unique duplex microstructure (Martensite-Austenite, Austenite-ferrite

Aerospace Manufacturing and Design

However, gas nitriding requires flammable gases such as ammonia, high gas consumption, and it can't treat rust- and acid-resistant steels. Recent advancements in pulse plasma nitriding provide a new level of precision and control, resulting in uniform and consistent case hardening and enabling the use of environmentally friendly gases.

JGS Nitriding

Less distortions than gas nitriding because plasma nitriding is performed at a lower temperature and under a vacuum. Higher surface, case, and core hardness than gas nitriding. Excellent wear resistance: the plasma ion nitriding process produces a compound zone that is dense, nonporous, very hard but not brittle, and has a low coefficient of friction.
