Description
Изобретение относитс к способам электрохимического обезжиривани изделий из цинковых сплавов в щелочных растворах перед нанесением защитно-декоративных гальванических покрытий.The invention relates to methods of electrochemical degreasing products from zinc alloys in alkaline solutions before applying protective and decorative electroplating.
Известные способы такого рода не обеспечивают прочного сцеплени гальванических покрытий с поверхностью изделий из цинковых сплавов- Дл устранени указанного недостатка предлагаетс изделие перед нанесением гальванического покрыти подвергать анодному обезжириванию в растворе, содержащем по 10 г/л фосфорнокислого, углекислого и едкого натри и 20 г/л жидкого стекла.Known methods of this kind do not provide a strong adhesion of electroplating to the surface of zinc alloy products. liquid glass.
Приготовление раствора осуществл етс растворением всех компонентов в гор чей воде. Температура ванны при обезжиривании составл ет 70-80°, врем обезжиривани 15-30 сек. Анодна плотность тока 2-2,5 а/дм.The preparation of the solution is carried out by dissolving all the components in hot water. The temperature of the bath during degreasing is 70-80 °, the degreasing time is 15-30 seconds. Anode current density 2-2.5 a / dm.
Предлагаемый способ электрохимического обезжиривани обеспечивает получение на издели х из цинковых сплавов прочных и неотслаивающихс декоративно-защитных покрытий из меди, никел и хрома и может найти щирокое применение в автомобильной промыщленности.The proposed method of electrochemical degreasing provides durable and non-peeling decorative protective coatings made of copper, nickel and chromium on zinc alloy products and can find widespread use in the automotive industry.
Предмет изобретени Subject invention
Электрохимический способ щелочного обезжиривани деталей из цинковых сплавов, отличающийс тем, что, с целью лучщей подготовки поверхности перед нанесением защитно-декоративных покрытий , примен ют анодное обезжиривание в растворе, содержащем по 10 г/л фосфорнокислого, углекислого и едкого натри и 20 г/л жидкого стекла.The electrochemical method of alkaline degreasing of parts made of zinc alloys, characterized in that, in order to better prepare the surface before applying protective and decorative coatings, anodic degreasing is used in a solution containing 10 g / l of phosphate, carbonate and caustic sodium and 20 g / l liquid glass.
