Kinetics simulation of TiB2 layers on the titanium alloy (Ti6Al4V) obtained by liquid boriding process.

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. [ABSTRACT FROM AUTHOR]
