Claims (1)

Способ электролитического хромирования при 70-120 г/л хромового ангидрида в электролите, имеющем в качестве комплексного фторидсодержащего соединения искусственный технический криолит, заключающийся в саморегулировании концентрации сульфат-ионов на основе сульфата стронция и соединения стронция/оксида, гидроксида, карбоната или хромата/, вводимого для уменьшения растворимости сульфата стронция, отличающийся тем, что концентрация вводимого соединения стронция определяется из соотношения по массе Sr2+ • CrO3 = 250 - 270 с последующим пересчетом на формулу этого соединения.The method of electrolytic chromium plating at 70-120 g / l of chromic anhydride in an electrolyte having an artificial technical cryolite as a complex fluoride-containing compound, which consists in self-regulation of the concentration of sulfate ions based on strontium sulfate and compounds of strontium / oxide, hydroxide, carbonate or chromate / introduced to reduce the solubility of strontium sulfate, characterized in that the concentration of the introduced strontium compound is determined from the mass ratio Sr 2+ • CrO 3 = 250 - 270, followed by recalculation ohm for the formula of this compound.
