| Popis: | TiB 2 coatings on Mo substrates were electrodeposited out of a FLiNaK electrolyte in the presence of TaCl 5 additive. The results show that a low concentration of TaCl 5 in the melt changes significantly the chemical composition and consequently, the properties of the coatings. The energy-dispersive X-ray analysis indicates up to 10 atom % Ta in the TiB 2 coatings. X-ray phase analysis demonstrates the changes in the texture of TiB 2 in the (001) direction. Codeposition of TaB 2 in a TiB 2 layer decreases the grain size and improves the smoothness of the layer. Addition of TaCl 5 in the electrolyte permits to obtain TiB 2 -TaB 2 layers of high quality and makes the process reproducible. In addition, the individual electrochemical behavior of the starting compounds, K 2 TiF 6 , KBF 4 , and TaCl 5 , as well as their mixtures was investigated in the FLiNaK electrolyte by means of cyclic voltammetry. |
