Abstract
Electroplating of chromium has been investigated in molten FLINAK (46.5 LiF-11.5 NaF-42.0 KF; mol %) over a temperature range of 600 to 1000°C. When Cr(III) is the electroactive species employed, a considerable amount of Cr(II) must be generated before chromium metal is deposited. Various parameters were tested to establish the optimum conditions for obtaining a smooth and thick chromium plating. Bath temperature was found to be a most important parameter; at temperatures above 870°C a smooth plate can be obtained, while at lower temperatures the deposits consist of extensive dendrites embedded in the salt which is the first reduction product of Cr(III).
