Llization performed from XRD spectra. Within this case the intensity of (0 0 0 1) peak (Figure eight) can also be the lowest, which suggests that coatings are a lot more amorphous. Moreover, decrease in boron content and creation of vacancies can influence this mechanical house.Table five. Measured and recalculated hardness (Equation (1)) of deposited coatings.
