Concept of an Economical and Ecological Process of Gas Nitriding of Steel
-
L. Małdziński
Abstract
An economical, ecological version of the gas nitriding process is presented. It allows a substantial reduction in the consumption of industrial gases compared with currently used processes. Also it leads to a simplification of nitriding installation as well as the process itself, while allowing maintenance of full control over the kinetics of the layer growth. The concept was developed from studies of the thermodynamics and kinetics of growth of nitrided layers on iron and steel. It has been verified in trials under industrial conditions.
Kurzfassung
Es wird eine ökonomische, ökologische Möglichkeit des Nitrierprozesses mit Gas vorgestellt. Der Prozess ermöglicht eine beträchtliche Herabsetzung des Verbrauchs an industriellen Gasen im Vergleich mit anderen zuständigen Prozessen. Er kann auch zu einer Vereinfachung der Anlage und des Nitriervorganges selbst führen, indem volle Kontrolle über die Schichtwachstumskinetik besteht. Der Prozessentwurf wurde auf thermodynamischen und kinetischen Betrachtungen des Nitrierschichtwachstums auf Eisen und Stahl gestützt. Die Idee wurde experimentell in industriellen Verhältnissen überprüft.
