Simulation of Nitriding Processes

This paper presents a new approach for predicting nitriding and nitrocarburizing results. The model calculates thermodynamic and kinetic effects based on material composition and pre-nitrided conditions. It can simulate up to three-stage recipes with varying temperatures, nitriding potentials, and carburizing potentials while also taking nucleation time into account. The simulation result gives compound layer thickness, precipitation layer, and total diffusion depth and calculates surface hardness, core hardness, and effective case depth.
