Abstract
In this study, we conducted a kinetics simulation of TiB2 layers obtained by the boriding process in the temperature range of 1123–1323 K. To investigate the influence of different boriding parameters, we developed a mathematical model based on Fick’s law and the mass balance equation. This model allows us to estimate the boron concentration in the TiB₂ phase, the boride layer thickness, and the mass gain. To validate the simulation results, we compared them with our experimental data on liquid boriding with a salt bath consisting of 70 % Borax (Na2B4O7) and 30 % Silicon carbide (SiC) applied to the titanium alloy (Ti6Al4V). The comparison confirmed the validity of our model, assuring the accuracy of our simulation results.
