The process of rhenium electrochemical deposition from fluorine-containing
electrolytes has been investigated. The light-coloured metal rhenium
coating electrodeposition rate has been found to be 3-4 times
higher than that in known sulfate electrolytes. The thickness of coatings
obtained during one electrodeposition-annealing cycle is 3-5 mum,
while that for sulfate electrolytes, 1-2 mum. Coatings can
be deposited onto copper, kovar, molybdenum, stainless steel, and
other substrates. It is possible to obtain black rhenium coatings
of oxide-hydroxide type exhibiting high a light absorption coefficient
(96-97 %). Those can be used as antiemission coatings.
