Abstract
The paper presents experimental results of the influence of carburizing time of iron powder samples on the carbon content in the sample’s depth by layers, subjected to a GCS (Gas-Carburizing Sintering) method. Sintered steel elaboration by GCS method consist of enriching the Fe powder with carbon in gas medium in a single thermal cycle including the carburising operation followed by sintering, thereby achieving the sintered carbon steel. Numerical simulations was made using Abaqus/CAE software for mass diffusion analysis in order to find the appropriate diffusion coefficient value.
Keywords: gas-carburizing, sintering, mass diffusion analysis.
