Abstract

This article presents two case studies controlled nitriding and gas nitrocarburizing of steel using the ZeroFlow method for automotive and wind gear applications. Both nitriding and nitrocarburizing using this method enables the precise forming of diffusion layers in the phase structure and zones (phases) thickness of hardness distribution. These processes are characterized by lower ammonia consumption during nitriding, and lower ammonia and carbon dioxide consumption during nitrocarburizing when compared with currently used processes. They are also characterized by a much lower emission of subprocess gases to the environment. The ZeroFlow method of nitriding and nitrocarburizing utilizes a simplified system for gas adjustment and control.
