Description
Способ электрополпровкп с применением в качестве олектро.тита раствора соедппепп фосфорной п серпоп зхпслот с хромовым ангидридом в воде известен.The method of electroplating with the use of a solution of a compound of phosphoric n serpop sphslot with chromic anhydride in water as an electro-tite is known.
Описываемый способ электрополировки алюминиевых сплавов п сталей отлнчаетс от нзвестного тем, что электролит состоит из раст1юра фосфорной кислоты и хромового ангидрида, но не содержит серио кислоты, кроме этого он предусматривает применение в качестве электролита дл электрополировки алюминиевых сплавов АК-2, АК-5, AVx-G. дюрал и сталей 50ХФА, 40ХНМА, ЗОХГСА п 7330 раствора, состо щего из:The described method of electropolishing aluminum alloys and steels is excluded from the fact that the electrolyte consists of phosphoric acid and chromic anhydride, but does not contain serio acid, and it also provides for electroplating AK-2, AV-5 aluminum alloys as electrolyte for electropolishing. -G. Dural and steels 50HFA, 40HNMA, ZOHGSA p 7330 solution consisting of:
