Abstract
Изобретение относитс к защите металла от коррозии и может быть использовано в электротехнической, радиотехнической, приборостроительной и легкой промышленности. Цель изобретени - повышение эффективности защиты от коррозии, повышение блеска поверхности, выхода по току и сцеплени поверхности при последующем латунировании. Это достигаетс за счет дополнительного введени красител хромового красного ализаринового и использовани в качестве кислоты - лимонной кислоты. Раствор содержит, кг/м3: лимонна кислота 1-5The invention relates to the protection of metal against corrosion and can be used in electrical, electronic, instrument-making and light industry. The purpose of the invention is to increase the effectiveness of corrosion protection, increase the surface gloss, current efficiency and surface adhesion during subsequent brass coating. This is achieved by additionally introducing a chromic red alizarin dye and using citric acid as the acid. The solution contains, kg / m 3 : citric acid 1-5

Description
Изобретение относитс к защите металлов от коррозии и может быть использовано в электротехнической, радиотехнической, приборостроительной и легкой промышленности.The invention relates to the protection of metals against corrosion and can be used in electrical, radio, instrument engineering and light industry.
Цель изобретени - повышение эффективности защиты от коррозии, повышение блеска поверхности, повышение выхода по току и сцепление поверхности при последующем латунировании .The purpose of the invention is to increase the effectiveness of corrosion protection, increase the gloss of the surface, increase the current efficiency and grip the surface during the subsequent brass coating.
Изобретение иллюстрируетс примерами (см. табл. 1,2).The invention is illustrated by examples (see Table 1.2).
Раствор готовили растворением в дистиллированной воде рассчитанного количества лимонной кислоты и красител хромового красного ализаринового (КХКА).The solution was prepared by dissolving a calculated amount of citric acid and a dye of chromic red alizarin (KHCA) in distilled water.
Обработку изделий из цинкового сплава ЦАМИ-1 проводили при 18-25 С в течение 60 с.The processing of zinc alloy ZAMI-1 products was carried out at 18-25 C for 60 s.
В табл. 1 приведены составы растворов , в табл. 2 - результаты обработки .In tab. 1 shows the composition of the solutions in the table. 2 - processing results.
Технико-экономическими преимуществами предлагаемого раствора вл ютс , повышение эффективности защиты от коррозии, блеска поверхности, выхода по току и сцепг.ени поверхности при последующем латунирсзании.The technical and economic advantages of the proposed solution are an increase in the effectiveness of protection against corrosion, surface gloss, current efficiency and surface adhesion upon subsequent brassing.
