Description
Изобретеиие заключаетс в получении электролизом тройного сплава; цинк-ка,Д|Мий-н|икель, с целью предохранени металлов в услови х морской практи1К1и от коррозии.The invention is to obtain a triple alloy by electrolysis; zinc-ka, D | Mii-n | ikel, in order to protect metals in the conditions of marine practice from corrosion.
Химический анализ получеиного тройного сплава , что в нем находитс : 8С% щивка, 10% кадми и lOlii никел . Коррозионна устойчивость такого сплава соот|ветству ет устойчивост1и двойного сплава цинккад М ,ий, однако, тройной сплав и:меет большую твердость. Осаждение тройного сплава произво|дитс в ванне, состо щей из; 40 г/л окиси цинка, 260 г/л цианистого натра, 80 г/л едкого натра, 12 г/л сернокислого кадми и 6,5 г/л сернокислого никел . Ансчды изготовл ютс из сплава 70% цинка и 30% кад|М1И .Chemical analysis of the semi-triple alloy that it contains: 8 ° C, 10% cadmium and lOlii nickel. The corrosion resistance of such an alloy complies with the stability of a double zinc oxide M alloy, however, the ternary alloy also has a greater hardness. Deposition of the ternary alloy is carried out in a bath consisting of; 40 g / l of zinc oxide, 260 g / l of cyanic sodium, 80 g / l of caustic soda, 12 g / l of cadmium sulphate and 6.5 g / l of nickel sulphate. Anchors are made from an alloy of 70% zinc and 30% cad | M1I.
