Nitrocarburizing

The term nitrocarburizing means an enrichment of the surface layer of ferrous materials with nitrogen and a small amount of carbon. This thermochemical treatment improves the wear resistance and the fatigue strength.

Used with a strongly oxidizing cooling bath - TENIFER®-QPQ - wear and corrosion resistant surfaces with an attractive black appearance are produced.

Products used in nitrocarburizing

• TF1 cyanide-free top-up salt for TENIFER® baths*; used for treating ferrous materials. Used only in combination with the REG 1 regenerator. Working temperature 480 - 630°C.
• REG 1 environment-friendly, nontoxic regenerator for TF 1 baths
• AB 1 oxidative salt for cooling parts treated in TF 1 baths; greatly enhances the corrosion resistance (TENIFER®QPQ process). The well-known traditional Durferrit NS salts are still available*.
