Abstract

FIELD: electroplating. SUBSTANCE: proposed electroplating vat has amorphous surface-active substance, water-soluble salt containing bivalent tin, water-soluble zinc salt and water being the balance. In electroplating vat formed surface film includes homogeneous composition of alloy even if current density changes in wide range. Therefore surface film having homogeneous composition of alloy can be formed on substrate of complex shape and chromate treatment tuns satisfactory. EFFECT: improved quality and stability of coat, increased production of high-quality film of tin-zinc alloy.

Гальваническая ванна сплава олово - цинк содержит амфотерное поверхностно-активное вещество, водорастворимую соль, содержащую двухвалентное олово, водорастворимую цинковую соль и остальное - вода. При применении предложенной гальванической ванны сплава олово - цинк формируемая покровная пленка содержит однородную композицию сплава даже в случае, когда плотность тока изменяется в широком диапазоне. Следовательно, покровная пленка, имеющая однородную композицию сплава, может быть сформирована даже на подложке, имеющей сложную форму, и хроматная обработка становится удовлетворительной. В результате эффект покрытия улучшается, полученное изделие является стабильным, и производительность увеличивается. Таким образом может быть обеспечена покровная пленка сплава олово - цинк, имеющая высокое качество.A tin-zinc alloy plating bath contains an amphoteric surfactant, a water-soluble salt containing divalent tin, a water-soluble zinc salt, and the rest is water. When using the proposed tin-zinc alloy plating bath, the formed coating film contains a homogeneous alloy composition even when the current density varies over a wide range. Therefore, a coating film having a uniform alloy composition can even be formed on a substrate having a complex shape, and chromate treatment becomes satisfactory. As a result, the coating effect is improved, the resulting product is stable, and productivity is increased. Thus, a tin-zinc alloy coating film of high quality can be provided.
