Heat treatment fluidized bath

nitriding

Fluidised bed/salt bath nitriding/nitrocarburising is utilised to improve components’ wear resistance, fatigue strength and corrosion resistance. Benefits of fluidised bed/salt bath nitriding/nitrocarburising Fluidised bed/salt bath nitriding/nitrocarburising provides design and manufacturing engineers an opportunity to improve their products’ wear resistance characteristic. Wear tests consistently confirm the superior wear resistance of fluidised bed/salt bath nitrided/nitrocarburised parts over traditional or induction hardened or hard chrome plated surfaces. An example here could be on hydraulic shafts that have various applications across many industries. If the hydraulic shaft is used in an outdoor application the enhanced corrosion protection can also be enjoyed. On thinner material components improving the fatigue strength properties may allow for the engineer to design even lighter weight parts. Improved corrosion protection can be realised on steel, cast iron and sintered metal parts. Salt spray test results per ASTM B 117 and DIN 50021 show improved benefits from the fluidised bed/salt bath nitriding/nitrocarburising process over competing processes. Application & materials Fluidised bed/salt bath nitriding/nitrocarburising is a process used to improve the wear resistance, fatigue strength and, when combined with post oxidation through oxidative cooling, improved corrosion resistance on products made from steel, cast iron and sintered iron. Depending on the components’ application, fluidised bed/salt bath nitriding/nitrocarburising is used as an alternative to other surface engineering processes such as case hardening.
