Description
Изобретение относитс к способам электроосаждени сплавов, в частности, сплава цинк- никель. Известный способ электролитического осаждени сплава цинк - никель из электролита , содержащего сернокислые соли цинка и никел , натрий сернокислый, а также сернокислый аммоний и гидроокись аммони , в р де случаев не позвол ет получать износостойкие покрыти с высоким содержанием никел . Предлагаемый способ позвол ет получать износостойкие покрыти сплавом цинк - Никель с содержанием никел .11 -16%. Предлагаемый способ отличаетс о г известного тем, что в электролит ввод т полиэтилепполиамии , хлористый и едкий натрий, а также услови ми проведени процесса. Предлагаемый способ состоит в том, что электроосаждение сплава цинк - никель осуществл ют из электролита, содержащего сернокислые соли цинка и никел , натрий сернокислый , в который ввод т полиэтиленполиамин , хлористый и едкий натрий при следующем соотношении компонентов, г/л: Цинк сернокислый60- 90 Никель сернокислый69- 90 Натрий сернокислый20- 40 Полиэтиленполиамин150-210 Натрий хлористыйiC- 15 Натрий едкий15- 20 Процесс ве;дут при 15-50° С и катодной плотности тока 0,5-3,5 а1дм Получаемые .покрыти имеют мелкокристаллическую структуру, беспористы, хорошо сцеплены с основой. Покрыти сплавом цинк - никель, содержащие 14-16% никел , могут быть получены на детал х из стали, меди и ее сплавов в стационарных ваннах, в колоколах и барабанах. Содержание нИКел в сплаве в указанных пределах обеспечивает максимальную коррозионную стойкость покрытий. Примен емый электролит устойчив в работе. Предмет изобретени Способ электролитического осаждени сплава цинк - никель из электролита, содержащего сернокислые соли цинка и никел , натрий сернокислый, отличающийс тем, что, с целью получени износостойких покрытий с содержанием никел 11-16%, в электролит ввод т полиэтиленполиал-гин, хлористый и едкий натрий при следующем соотношении компонентов , г/л: Цинк сернокислый60- 90 Никель сернокислый60-90 Натрий сернокислый20- 40 Полиэтиленполиамин 150-210 Натрий хлористый10- 15 Натрий едкий15- 20 и процесс ведут при 15-50°С и катодной плотности тока 0,5-3,5 а/дм.The invention relates to methods for electrodeposition of alloys, in particular, zinc-nickel alloy. The known method of electrolytic deposition of a zinc-nickel alloy from an electrolyte containing sulphate of zinc and nickel, sodium sulphate, as well as ammonium sulphate and ammonium hydroxide, in some cases does not allow to obtain wear-resistant coatings with high nickel content. The proposed method allows to obtain wear-resistant zinc-nickel alloy coatings with a nickel content of .11 -16%. The proposed method differs in terms of the fact that polyethylene pupolyamia, sodium chloride and caustic sodium are introduced into the electrolyte, as well as the process conditions. The proposed method consists in that electrodeposition of a zinc-nickel alloy is carried out from an electrolyte containing zinc sulphate and nickel sulphate, sodium sulphate, in which polyethylenepolyamine, chloride and caustic sodium are introduced in the following ratio of components, g / l: Zinc sulphate60- 90 Nickel sulphate 69- 90 Sodium sulphate 20- 40 Polyethylenepolyamine 150-210 Sodium chloride i C- 15 Sodium hydroxide 15- 20 The process is carried out at 15–50 ° C and a cathode current density of 0.5–3.5 a1 dm. The resulting coatings have a fine-crystalline structure, are non-porous, okay sho linked with the base. Zinc-nickel alloy coatings containing 14-16% nickel can be obtained on steel, copper and its alloys in stationary baths, in bells and drums. The content of nickel in the alloy within the specified limits provides maximum corrosion resistance of the coatings. The electrolyte used is stable in operation. The subject of the invention. A method of electrolytic deposition of a zinc-nickel alloy from an electrolyte containing zinc sulphate and nickel sulphate, sodium sulphate, characterized in that, in order to obtain wear-resistant coatings with a nickel content of 11-16%, polyethylene is added to the electrolyte, chloride and caustic sodium in the following ratio of components, g / l: Zinc sulphate 60-90 Nickel sulphate 60-90 Sodium sulphate 20-40 Polyethylenepolyamine 150-210 Sodium chloride 10-15 Sodium sodium 15-20 and the process is carried out at 15-50 ° C and a cathode current density of 0, 5-3, 5 a / dm.
