摘要：

The electrodeposition of niobium from a binary electrolyte consisting of KF and NaF was characterized and compared with that from the ternary electrolyte of LiF, NaF and KF. The deposition experiments were conducted at current densities between 5 and 35 mA cm** minus **2 and electrolyte temperatures between 725 and 800 degree C. DTA measurements indicated the melting points to be 450 and 710 degree C for the ternary and binary electrolytes with added K//2NbF//7; however, it was necessary to operate both electrolytes above 725 degree C to obtain dense coherent deposits. Coating morphology was described by optical and scanning electron microcopy studies, while coating structure and properties were characterized by X-ray diffraction analysis.
