About Commercial Gaseous Ferritic Nitro Carburising
Gaseous ferritic nitrocarburizing is alsoknown as controlled nitrocarburizing, soft nitriding, and vacuumnitrocarburizing or by the tradenames "UltraOx", [18] "Nitrotec","Nitemper", "Deganit", "Triniding","Corr-I-Dur", "Nitroc", "Nitreg-C", [19] "Nitrowear",and "Nitroneg". [3] [20] Theprocess works to achieve the same result as the salt bath process, exceptgaseous mixtures are used to diffuse the nitrogen and carbon into theworkpiece. [21]
The parts are first cleaned, usually witha vapor degreasing process,and then nitrocarburized around 570 C (1,058 F), with aprocessing time that ranges from one to four hours. The actual gas mixtures areproprietary, but they usually contain ammonia and an endothermic gas. [21]
In comparison to a standard nitridingprocess, ferritic nitrocarburizing or FNC in a vacuum furnace takes less timeto achieve case depth requirements - mainly in part due to the addition ofcarbon to achieve faster diffusion. [22]
What is Gaseous Ferritic Nitro Carburising?
GFNC is a thermochemical surface treatment process applied to steel components to improve their surface hardness and corrosion resistance. By exposing steel to an ammonia-enriched atmosphere at controlled temperatures, nitrogen and carbon are diffused into the steel surface, resulting in a wear-resistant, hard outer layer. The process is automated for quality and repeatability.
How is the GFNC Process Controlled?
The entire nitrocarburising process is automated, using advanced process control systems to ensure consistent case depth, hardness, and minimal distortion. This automation guarantees uniform results across batches, making the process reliable for critical component applications.
Benefits of Gaseous Ferritic Nitro Carburising
This technique increases surface hardness (up to 720 HV), enhances corrosion resistance, and greatly reduces component wear over time. The minimal distortion during treatment maintains the integrity and dimensional stability of precision steel components, making it ideal for demanding industrial applications.
FAQ's of Gaseous Ferritic Nitro Carburising:
Q: How does Gaseous Ferritic Nitro Carburising enhance steel components?
A: This process enriches the steel surface with nitrogen and carbon, which increases hardness (up to 720 HV) and corrosion resistance. The result is a durable, wear-resistant component with extended service life.Q: What types of materials are suitable for this treatment?
A: GFNC is ideal for low and medium carbon steels as well as alloy steels. These materials respond well to the process, achieving the desired case depth and hardness.Q: When is it best to use GFNC on steel components?
A: GFNC is recommended when components demand superior surface hardness, enhanced corrosion resistance, and minimal dimensional distortion, such as in automotive, tool, and engineering applications.Q: Where can the GFNC service be performed?
A: GFNC can be carried out either at the customer's site or in specialized service centers equipped with automated process control systems throughout India.Q: What is the typical process temperature and duration for GFNC?
A: The process operates at temperatures between 570C and 590C. The exact treatment duration varies based on job requirements and desired case depth, ensuring flexibility for different applications.Q: How consistent is the result with automated GFNC process control?
A: Automated process control ensures uniformity in case depth, surface hardness, and minimized distortion across every batch, delivering reliable and repeatable results.Q: What are the key benefits of choosing Gaseous Ferritic Nitro Carburising?
A: Major advantages include significantly increased surface hardness, improved corrosion resistance, minimal component distortion, and extended service life for steel parts, making it a preferred choice in high-performance environments.- Minimum Order Quantity
