It is a new nitriding process that can harden metal surfaces while suppressing surface roughness using plasma nitriding.
Radical nitriding is a plasma nitriding method based on a new concept that was jointly developed by our company and Sumitomo Metal Mining Co., Ltd. It can form only a hardened layer (nitrided layer) within the metal surface while suppressing the roughness of the metal surface without creating a compound layer. Additionally, since masking is possible, treatment can be applied only to the necessary areas. This improves the wear resistance of molds, various machine parts, and tools.

basic information
【Features】 ○ The occurrence of edge defects and heat cracks in molds and tools can be improved. Additionally, there are no dimensional changes or distortions caused by the compound layer. ○ Optimal nitriding conditions can be selected according to the material and shape of the key parts. Partial nitriding prevention is also easy. ○ The surface condition after treatment shows minimal reduction in surface roughness and remains in good condition. ○ In combined treatments with PVD processing, the significant hardness difference between the hard film and the product surface can be alleviated, further enhancing the adhesion and durability of the hard film. ○ The nitrided areas after radical nitriding can be welded. Moreover, since there is no compound layer, plating is also easy. ● For other functions and details, please download the catalog or contact us.

Company information
Our company started operations in April 1957 in Mitaka, Tokyo, as a job shop specializing in high-frequency hardening using high-frequency induction technology. In 1973, we developed and commercialized the first domestic plasma heat treatment device, "ion nitriding." Today, we respond to the needs of the industry as a professional group in heat treatment, utilizing cutting-edge technologies based on ceramic coating, plasma heat treatment, and high-frequency induction heating. Additionally, our plasma heat treatment device, "ion nitriding device," along with other heat treatment equipment utilizing our unique technology, has received high acclaim not only in Asia but also internationally. We will continue to strive for the development of industry and the realization of a prosperous society through creativity and a spirit of challenge in heat treatment.
