  The old creation method of this coating is using salt bath for an approximate
time of 6 to 10 hours, which means wasting a lot of time and energy while the
formation of this coating with the plasma electrolytic method just takes about
15 minutes and it can increase the efficiency strongly on an industrial scale.
In this research, the process has been applied on the samples of 1.2436 steel
in different periods. Then, thickness of the coating layers has been measured
by using SEM images and thermodynamic data of Vanadium carbide formation. These
results have been expanded to access and present a confirmed model to predict
the thickness of this diffusion-based coating as a function of time and
reaction temperature. The proven model can be used to demonstrate and prove the
kinetic advantage of this method and also find the optimal value of applying
time and temperature.
