One of the most common diffusion treatments is the treatment with nitrogen, carbon and a combination thereof. When these elements are diffused in, a nitriding zone is formed which is divided into a wear-resistant compound layer on the surface and an underlying diffusion layer. The characteristics of these zones and the associated properties, such as the hardness-depth profile or the chemical resistance, can be specifically configured through the treatment parameters. In addition, the adhesion of subsequent coatings can be improved.
Each application requires a diffusion zone which is specially tailored to the load situation. In addition to the chemical composition, this is dependent on further factors such as the microstructure and morphology. With the expertise and experience gained from many years of research activities, the Fraunhofer IST would be pleased to provide you with support in the modification and optimization of your edge zones.
