Description
Известны различные пирофосфатные электролиты дл бронзировани .Various pyrophosphate electrolytes are known for bronzing.
Дл повышени содержани олова (до 40- 50%) в сплаве и получени однородных по составу покрытий на рельефных издели х предлагаетс процесс электроосаждени вести при рН 7,3-8,5, температуре 18-25°С и плотности тока 0,25-0,80 а/дм в электролите следующего состава (г/л).To increase the tin content (up to 40-50%) in the alloy and to obtain homogeneous composition of coatings on embossed products, it is proposed to conduct the electroplating process at a pH of 7.3-8.5, a temperature of 18-25 ° C and a current density of 0.25- 0.80 a / dm in the electrolyte of the following composition (g / l).

Электролит готов т растворением в отдельных емкост х хлорной меди и пирофосфорнокислого кали с учетом примен емого избытка против необходимого дл образовани комплексов . К раствору хлорной меди приливают раствор пирофосфорнокислого кали до полного растворени медной соли, после чего в оставшемс растворе пирофосфорнокислогоThe electrolyte is prepared by dissolving in separate containers of chlorine copper and potassium pyrophosphate, taking into account the excess used against the necessary for the formation of complexes. A solution of potassium pyrophosphate is poured to the copper chloride solution until the copper salt is completely dissolved, and then in the remaining pyrophosphate acid solution
