Description
ЭЛЕКТРОЛИТ ДЛЯ ОСАЖДЕНИЯ СПЛАВА МЕДЬ - ОЛОВОELECTROLYTE FOR DEPOSITION OF ALLOUS COPPER - TIN
Известны различные электролиты дМ йолу4ени покрытий сплавов медь - олово, в том чйсЛе и на основе сернокислых солей с добавками органических веществ.There are various electrolytes dM Yol4i coatings of copper-tin alloys, including those based on sulphate salts with the addition of organic substances.
Предложенный электролит вл етс проСтьш по составу и устойчив в работе. Покрытий имеют хорошее сцепление со сталью и по внешнему виду не уступают осадкам, полученным из цианистых электролитов бронзировани . Электролит отличаетс от известных тем, что он содержит фенолсульфоновую кислоту и включает сернокислые соли меди и олова лри следующем соотношении компонентов , г/л.The proposed electrolyte is prostat composition and stable in operation. The coatings have good adhesion to steel and in appearance are not inferior to sediments obtained from cyanide electrolytes of bronzing. The electrolyte differs from the known ones in that it contains phenolsulfonic acid and includes sulfate salts of copper and tin in the following ratio of components, g / l.

сернокислое олово30-50sulfate tin 30-50
фенолсульфонова кислота (80э/она )80-90.phenolsulfonic acid (80e / she) 80-90.
При использовании предложенного электролита процесс ведут при комнатной температуре .When using the proposed electrolyte process is carried out at room temperature.
Катодный и анодный выход по току 90- 95о/о, скорость осаждени сплава равна0 ,5 MK.JMUH при плотности тока 1 а1дм.Cathode and anode current output 90-95 o / o, the deposition rate of the alloy is 0, 5 MK.JMUH at a current density of 1 a1 dm.
Из электролита получают осадки бронзь, содержащие от 10 до 50о/о олова и от 90 до 50% меди.From the electrolyte, bronze deposits are obtained containing from 10 to 50 ° / o tin and from 90 to 50% copper.
Оптимальные режимы дл получени покрытий сплавов медь олово следующие: дл сплава lOVo меди (желта бронза) плотность тика от 0,5 до 1 при неподвижном катоде и до 5 ajdAis- при движении катода со скоростью 200 м/мин; дл сплава 50Vo олова и 50,3/0 меди (бела бронза) плотность тока от 1 до 2 а/дм при неподвижном катоде и до 8 й/Ли2 при движении катода до 200 м/мин.The optimal modes for obtaining copper-tin alloy alloys are as follows: for the lOVo copper alloy (yellow bronze), the tick density is from 0.5 to 1 at a fixed cathode and up to 5 ajdAis- when the cathode moves at a speed of 200 m / min; for alloy 50Vo tin and 50.3 / 0 copper (white bronze) current density from 1 to 2 a / dm at a fixed cathode and up to 8 th / Li2 when the cathode moves up to 200 m / min.
Предмет изобретени Subject invention
Электролит дл осаждени сплава медь - олово на основе сернокислых солей, отличающийс тем, что, с целью повышени стабильности электролита, в его состав ввод т фенолсульфоновую кислоту при следующем соотношении компонентов, в г/л:The electrolyte for the deposition of the copper-tin alloy based on sulfate salts, characterized in that, in order to increase the stability of the electrolyte, phenolsulfonic acid is introduced into it in the following ratio of components, in g / l:
