已经开发了一种用于将IVB族、VB族和VIB族的九种难熔金属中的八种电沉积为致密的连贯沉积物的通用方法。它基本上由在熔融碱-氟化物共沸混合物中的难熔金属氟化物溶液的电解组成，并且已经显示出通过遵守法拉第定律的过程来存款与基底非合金化的涂层。一些证据表明，从熔盐中沉积连贯涂层的电极反应机制包括不可逆的金属生产步骤。
A general process has been developed for the electrodeposition of eight of the nine refractory metals of groups IVB, VB, and VIB as dense coherent deposits. It consists essentially of the electrolysis of a solution of the refractory metal fluoride in a molten alkali-fluoride euteotic mixture, and has been shown to deposit a coating, unalloyed with the substrate, by a pro- cess that obeys Faraday's law. Some evidence exists that the electrode-reaction mechanism by which coherent coatings are deposited from molten salts incorporates an irreversible metalproducing step.
