摘要：

Electrodeposition of TiB2 has been performed in cryolite-based electrolytes at 960 degrees C and in KF-KCl melts at 800 degrees C. As electroactive species either boron oxide and titanium oxide or potassium tetrafluoroborate and potassium hexafluorotitanate were used. Preparation of coatings from cryolite-based electrolytes containing K2TiF6 and KBF4 was not successful. Coatings prepared from cryolite-based electrolytes containing B2O3 and TiO2 were not coherent. Owing to the relatively high temperature both types of electrolytes undergo thermal decomposition. Electrolysis in potassium fluoride-chloride electrolytes containing KBF4 and K2TiF6 provides coherent coatings with good adhesion to the substrate.
