Description
Известны способы электролитического получени сплава никель- хром, например, из электролита, содержащего 250 г/л хромового ангидрида , 250 г/л сернокислого никел и 25 г/л борной кислоты. Выход потоку при этом составл ет 7-9%, а плотность тока - 30-35 а/дм.Known methods for the electrolytic production of an alloy of nickel-chromium, for example, from an electrolyte containing 250 g / l of chromic anhydride, 250 g / l of nickel sulphate and 25 g / l of boric acid. The yield to the stream is 7-9%, and the current density is 30-35 A / dm.
Предлагаемый способ позвол ет вести процесс при повышенной плотности тока 40-90 а/дм и получить большой выход по току, равный 60-70%. Электролитическое покрытие в виде сплава никел с хромом, содержащее последнего до 20%, характеризуетс значительной стойко стью в окислительных средах, повышенной жаропрочностью и высоким электрическим сопротивлением.The proposed method allows the process to be conducted at an increased current density of 40-90 a / dm and to obtain a large current efficiency equal to 60-70%. The electrolytic coating in the form of an alloy of nickel with chromium, containing the latter up to 20%, is characterized by considerable resistance in oxidizing environments, increased heat resistance and high electrical resistance.
Преимущества предлагаемого способа обусловлены применением электролита, содержащего: борфтористоводородного хрома в пересчете на хром 60-85 г/л, борфтористоводородного никел в пересчете на никель 12-20 г/л и борфтористоводородной кислоты (свободной) 250-650 г/л. Процесс ведетс при 70-80° и соотношении хром-никел. в электролите 5:1.The advantages of the proposed method are due to the use of an electrolyte containing: hydrofluoric chromium in terms of chromium 60-85 g / l, hydrofluoric nickel in terms of nickel 12-20 g / l, and hydrofluoric acid (free) 250-650 g / l. The process is conducted at 70-80 ° and the chromium-nickel ratio. in electrolyte 5: 1.
Возможна работа электролита с растворимыми анодами (нихром - 20% Сг и 80% Ni), что позвол ет сохранить баланс металлов в электролите при заданном составе. Перемешивание электролита способствует повышению качества катодных осадков. Содержание хрома и никел определ етс обычными методами химического анализа.The electrolyte can work with soluble anodes (nichrome — 20% Cr and 80% Ni), which allows maintaining the balance of metals in the electrolyte with a given composition. Mixing electrolyte contributes to the quality of cathode precipitation. The chromium and nickel content is determined by conventional chemical analysis methods.
