摘要：Electrodeposition of TiB2 coating provides a convenient and low-cost way in preparation of TiB2 material. In this paper, TiO2 and B2O3 were selected as the active components, KF-LiF as the supporting electrolyte, Ti4+ ions and B3+ ions reduction processes in TiO2-B2O3-LiF-KF melts were investigated by cyclic voltammograms. Then electrodeposition of TiB2 onto graphite substrate was carried out from TiO2-B2O3-LiF-KF melts at 800 degrees C by using CCP (continuous current plating) and PCP (pulsed current plating). The TiB2 coatings prepared by PCP exhibit uniform, dense and metallic surface with good dherence to the substrate, but with more cracks, compared with those obtained by CPC.
