  • Estimation of the boron diffusion coefficients in FeB and Fe2B layers during the pack-boriding of a high-alloy steel = Določanje koeficienta difuzije bora v plasteh FeB in Fe2B med boriranjem visoko legiranega jekla v skrinji
    Abdellah, Zahra Nait ; Keddam, Mourad
    In this work we propose a diffusion model to estimate the boron diffusion coefficients in FeB and Fe2B layers during the pack-boriding of AISI M2 steel in the temperature range 1173-1323 K for a ... treatment time of 4-8 h. The proposed model is based on the mass-balance equations at the two growth fronts- FeB/Fe2B and Fe2B/substrate - under certain assumptions. The estimatedvalues of the boron activation energies in the FeB and Fe2B layers were compared with the literature data. The present model was extended to predict the thickness of each boride layer for the borided samples at different temperatures for 10 h. Iso-thickness diagrams were established to beused as a tool for predicting the thickness of each boride layer as a function of the two parameters: temperature and time. Finally, a simple equation was proposed to estimate the required time to obtain a single Fe2B layer by diffusion annealing.
