Description
Предметом изобретени вл етс способ электролитической полировки в электролите, содержащем хромовый ангидрид. В предлагаемом способе, с целью регенерации электролита путем окислени накапливающегос трехвалентного хрома в шестивалентиый, примен ют дополнительно свинцовый анод, включенный параллельно с детал ми, подвергающимис полировке.The subject invention is an electrolytic polishing method in an electrolyte containing chromic anhydride. In the proposed method, in order to regenerate the electrolyte by oxidizing the accumulating trivalent chromium to hexavalent, an additional lead anode is used, connected in parallel with the parts subjected to polishing.
Пол ризационное сопротивление свинца при плотности тока 0,5 а/дм составл ет около 0,3 ома, а пол ризационное сопротивление деталей, подвергаемых электрополировке в том же электролите, составл ет 0,12 ома.The polarization resistance of lead at a current density of 0.5 a / dm is about 0.3 ohm, and the polarization resistance of parts subjected to electropolishing in the same electrolyte is 0.12 ohm.
Если параллельно полируемым детал м будет подключен дополнительно свинцовый анод, то при плотности тока электрополировки 20- 80 а/дм плотность тока на дополнительном аноде составит 8-32 а/дм.If an additional lead anode is connected in parallel to the parts to be polished, then with an electropolishing current density of 20–80 a / dm, the current density at the additional anode will be 8–32 a / dm.
При такой плотности тока выход по току шестивалентного хрома будет небольщой.With this current density, the hexavalent chromium current output will be small.
Дл повышени выхода по токуTo increase current output
шестивалентиого хрома в цепь дополнительных свинцовых анодов предложено включить последовательно .дополнительное регулируемое сопротивление, величина должна быть такой, чтобы плотность тока на анодах не превышала 0,5 .Hexavalent chromium in the chain of additional lead anodes is proposed to include in series. Additional adjustable resistance, the value must be such that the current density at the anodes does not exceed 0.5.
