Super Systems Inc. (SSi) recently designed a nitriding/ferritic nitrocarburizing (FNC) automated control solution for Cincinnati Steel Treating. The process changes the properties of the workpieces, increasing the metals' surface hardness while improving its resistance to corrosion. SSi's control-system design will provide precise control of temperature and process gases, including ammonia, oxygen, nitrogen and CO2. With this setup, the instrumentation and sensors will be used to accurately control the process and provide the required nitriding potential (Kn). The parts will be run in accordance with AMS 2759/12A Group 3, Class 2 process parameters and will meet CQI-9 requirements. The furnace used in the FNC process will continuously control compound layer with proper phase composition by using process gases and automatically controlling the nitriding and carburizing potentials. Along with the controls, SSi's SuperDATA system will be used for historical tracking of loads as well as real-time and historical process parameters.
