Nitriding - Wikipedia

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-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum. In 2015, nitriding was used to

The δ-phase, not shown on this dia- gram, exists from 11.0 to 11.35% N at temperatures .. schematic of an ion nitriding furnace layout is shown in Fig. 4.

Patent US8753457 - Nitrogen alloyed martensitic stainless steel and

Jun 17, 2014 The present inventive process for nitriding martensitic stainless steels comprises heating wrought iron martensitic stainless steel to a temperature of from about 900° F. (480° C.) to about 2500° F. (1370° C.) in a vacuum furnace in the presence of hydrogen or argon gas in order to clean the surface.

Aug 28, 2014 Also, since only free cooling takes place, rather than rapid cooling or quenching, no subsequent transformation from austenite to martensite occurs. Again, there is no molecular Nitriding is a ferritic thermo-chemical method of diffusing nascent nitrogen into the surface of steels and cast irons. This diffusion

Austempered steel becomes a form of steel called bainite, which is more ductile than martensite and does not require additional tempering. It is also stronger, tougher, and more resistant to wear for a given hardness than martensitic steels. Austempered ductile iron results in a structure called ausferrite, which has greater

The Use of Nitriding to Enhance Wear Resistance of Cast Irons and

Nov 5, 2012 ABSTRACT. This research is focused on using nitriding to enhance the wear resistance of austempered ductile iron (ADI), ductile iron (DI), and gray iron (GI), and 4140 steel. Three gas nitriding processes, namely “Gas nitriding + nitrogen cooled down to 800 o. F. (Blue)”, “Gas nitriding + cooled down to 300.
