Description

Существующий технологический процесс иикелировани  деталей из цинковых сплавов не обеспечивает равномерное покрытие деталей медным подслоем, что дает значительный брак по вспучиванию никелевого покрыти  при его полировке.The existing technological process of nickel zinc alloy parts does not ensure uniform coating of the parts with a copper underlayer, which gives a significant defect in the swelling of the nickel coating when it is polished.

Предлагаемым изобретением полностью устран етс  этот недостаток, что достигаетс  анодной пассиваин.ей цинковых изделий, проводимой в растворе пирск1зосфорнокислого с концентрацией 50-90 г-л до нанесени  на издели  медного подсло .The invention completely eliminates this drawback, which results in anodic passivation of zinc products, which is carried out in a phosphoric acid solution with a concentration of 50-90 gl before the copper sublayer is applied to the products.

При анодном пассивировании на поверхности деталей обр азуетс  пленка из фосфатов цинка, котора  имеет наибольи1ую толплшу на выпук;1ых част х деталей, в то врем  как в порах и к вогнутых част х деталей пленки почти нет.By anodic passivation, a zinc phosphate film is formed on the surface of the parts, which has the largest crowd on the bulge; there are almost no first parts of the parts, while in the pores and to the concave parts of the parts of the film.

Температура ванны электролита при этом иринимаетс  в пределах (Ю-70°, врем  обработки 0,5- 1,0 мин., напр жение тока 12 в, анод )1а  плотность тока 5-6 а/дц.In this case, the temperature of the electrolyte bath is within the range of (10 ° –70 °, processing time 0.5–1.0 min., Voltage 12 V, anode) 1a current density 5–6 a / dz.

При нанесении медного но.чсло , после анодного пассивировани , на нздел1П1 покрываютс  сначала мелкие углублени , а затем - по мере растворени  пленки - - . остальные места деталей, чем достигаетс  их равномерное покрытие, после которого ПОЛ1 ровка по никелю и вспучипа(П1Я и устран ет брак.When a copper sheet is applied, after anodic passivation, small sections of the first section are covered first, and then - as the film is dissolved - -. the remaining parts of the parts, than their uniform coverage is reached, after which the nickel and elongation polishing is achieved (P1I and eliminates the defect.
