Salt bath nitriding has long been a popular surface treatment process in the metalworking industry, primarily used to enhance wear resistance, corrosion protection, fatigue strength and a cosmetic black finish. The process typically involves immersing components in a molten salt bath containing a mixture of alkali cyanides, cyanites, carbonates, and other nitrogenous compounds. This treatment…
read moreThe achievable surface hardness mainly depends on the base material. Alloying elements such as chrome and aluminium lead to higher hardness. The Nitriding depth depends on customer requirements. Also the component’s condition at delivery, i.e. distortion, heat treatment status also affect the layer parameter to be achieved. Dimensional changes can further be positively influenced by…
read moreThanks to the wide range of applications, Nitriding and Nitrocarburising processes are becoming more and more important. In addition to mechanical and technological characteristics, corrosion resistance is of vital importance for the functionality of surfaces. The Corr-I-Dur® process not only enhances wear properties, but also significantly improves the corrosion resistance. Corr-I-Dur® has very little effect on distortion and dimensional changes…
