В подогретой до воде раствор ют хлориды цинка, никел  и аммони  при интенсивном перемешивании, затем последовательно добавл ют уксусную кислоту и полиэткленгликоль. Карбонилсодержащее вещество, наприм ер сиреневый, вератровый , саотициловый или анисовый альдегиды, ввод т в раствор в виде водносниртового ИЛИ аммиачного раствора и довод т объем водой до 1 л.Zinc, nickel, and ammonium chlorides are dissolved in heated water until vigorous stirring, then acetic acid and polyethylene glycol are added successively. The carbonyl-containing substance, for example, violet, veratric, sao- ticyl or anisic aldehydes, is introduced into the solution in the form of a water-free OR ammonia solution and brought to volume with 1 l.

Рассеивающа  способность электролита (по методу Хулла) составл ет 43-72%, его стабильность - 90-110 Л .The dispersing capacity of the electrolyte (according to the Hull method) is 43–72%, its stability is 90–110 L.

Из данного электролита осаждают блест щие (42-65%), износостойкие (1,8- 2,6 ед.) и корроз;ион1ностой.кие (скорость коррозии, измеренна  гравиметрически по убыли веса в 3%-ном растворе хлорида натри  с добавкой 0,1% перекиси водорода составл ет 0,7-1,3 г/с.и час покрыти  со скоростью осаждени  2,5-6 мкм/мин, выходом по току 77-85% и содержанием никел  в сплаве 6,7-9,4%. Микротвердость покрытий составл ет 150-3GQ кг/мл-.Brilliant (42-65%), wear-resistant (1.8-2.6%) and corrosion; ion-resistant (corrosion rate measured gravimetrically by weight loss in a 3% solution of sodium chloride with the addition of 0.1% hydrogen peroxide is 0.7-1.3 g / s. And the hour of coating with a deposition rate of 2.5-6 µm / min, a current output of 77-85% and a nickel content of 6.7- 9.4%. The microhardness of the coatings is 150-3GQ kg / ml.

Изобретение может быть иропллюстрпровано несколькими примерами, представленными в таблице.The invention can be accomplished with several examples presented in the table.

Изобретение поз-вол ет в 2-3 раза повысить блеск и в 2-2,6 раза износостойкость покрытий.The invention allows to increase the gloss and coatings 2-2.6 times by 2-3 times.
