| Abstract: | Finite element model of the nitrogen diffusion during gas nitriding is calculated by numerical simulation in the paper,based on the second Fick law of modified diffusion equation. The air pressure,temperature and time of nitriding influence the nitrogen distribution in the metal surface layer. These process parameters are taken into consideration. The simulated results of nitriding depth and concentration distribution of N in the different process parameters are gained. This study is useful for selecting an... |
