Electrodeposition of [001] oriented TiB2 coatings

This paper focused on the preparation of titanium diboride (TiB2) coatings by electroplating in fluoride–chloride electrolytes (KF–KCl) containing K2TiF6 and KBF4 as the electrochemically-active components. X-ray diffraction (XRD) analyses indicated that the preferred orientation of TiB2 coatings is [001], which is in accordance with the prediction of the two-dimensional crystal nuclei theory. The effect of the current density on average crystal size and texture coefficient was also studied. Thermodynamic predictions and experimental results showed the substrate and TiB2 coatings bind physically.
