Plasma Nitriding Technology For Development In Industrial Applications

Nitriding technology ,developed  based on the glow discharge phenomenon , ranging from its basic physical principle, main processing characteristics  and technical advantages as well as its industrial applications.At Advanced Nitriding Solutions began as innovative gas nitriding process and gas nitriding technology.Our revolutionary proprietary gas nitriding technology brought greater wear,fatigue and corrosion resistance to ferrous and  non-ferrous materials ,qualities much sought after by anyone whose product manufacturing activities involve any heat treatment process.

PlasmaNitriding technology, developed based on the glow discharge phenomenon, is reviewed in this chapter, ranging from its basic physical principle, main processing characteristics and technical advantages, as well as its industrial applications.Other nonmetal element plasma surface alloying technologies, such as plasma carburizing, plasma Nitro-carburizing and plasma sulfurizing are briefly introduced. Further discussion is carried out on its limitation of the nonmetallic element for plasma nitriding technology and advanced technology development in China.The advantages of plasma ion nitriding are:

·         High diffusion speed –   Driving under plasma energy and high temperature,nitrogen ions can diffuse into the material

·         Energy saving –  Ion bombardment of the surface generates local heating on the working piece surface without heating the whole furnace body,thus the process can greatly minimize energy consumption.

·         Controllable microstructure –  In contrast to the gas nitriding process, the composition and microstructure of the nitride layer are controllable during the plasma nitriding process.

·         No requirement for any treatment for the passive film on stainless steel-

·         No chemical pollution –   plasma nitriding only uses a small amount of ammonia or nitrogen, hydrogen, the environmental pollution is negligible.

The FerriticNitro-carburizing imparts high surface hardness,improved wear resistance and fatigue resistance to a wide variety of carbon steel , alloy steel and cast iron parts.In many applications,FNC treatment also improves corrosion resistance through the formation of a continuous compound layer on the workpiece surface which can allow for the elimination of subsequent protective plating operations or application of rust preventive.Advanced Nitriding solutions supplement plasma furnaces with conventional gas nitriding solutions.We supply exclusive ferritic nitro-carburizing solutions with innovative applications delivering substantial advantages to the customers.
