Description
Известны кислые электролиты, пред11азначе1: 1ые дл рафиаировани висмута, напри1мер борфтористоводородные ::;лектролиты. Однако эти электролиты не пригодны дл получени сцепленных впсм -товых иОКрытий па свипце или освинцованных издели х. Описываемый способ гальванического покрыти позвол ет получить висмутовые покрыти на издели х из свинца, свинцовых сплавов или стальных освинцованных издели х и дает возможность сообщить поверхност л таких изделий антифрикционшзге свойства.Acid electrolytes are known, previously 11: 1: 1 for refining bismuth, for example, hydrogen fluoride:; electrolytes. However, these electrolytes are not suitable for the production of interlinked vsm-ovine coatings and SWITCHES or lead products. The described electroplating method makes it possible to obtain bismuth coatings on products made of lead, lead alloys, or leaded steel products and makes it possible to communicate the surface of such products with antifriction properties.
По предлагаемому способу примен ют щелочкой электролит, в котором висмут находитс в виде комплексной CO;IM и ко1-ггактное вытеснение его из раствора свинцом исключаетс . Процесс гальванического покрыти провод т при плотности тока катода 0,5 а/дм и температуре 70--75° в электролите следуюп;его состава:According to the proposed method, an electrolyte is used with an alkali in which bismuth is in the form of complex CO; IM and its displacement from solution by lead is eliminated. The process of electroplating is carried out at a cathode current density of 0.5 a / dm and a temperature of 70--75 ° in the electrolyte as follows: its composition:
висмута азотнокислого- 75 г/л.bismuth nitrate - 75 g / l.
глицерина-125 мл/л.glycerin-125 ml / l.
кали едкого общего- 65 г/л.potassium caustic total- 65 g / l.
кали едкого свободного- 15 г/л.potassium caustic free 15 g / l.
кислоты винной- 50 г/л.tartaric acid- 50 g / l.
Предмет изобретени Subject invention
Способ гальванического покрыти слоем висмута в щелочном электролите изделий из свинцовых сплавов или стальных осви цовапных изделий, отличающийс тем, что процесс провод т при плотности тока катода 0,5 а/дм и температуре 70-75° в электролите состава: азотнокислого висмута 75 г/л. глицерина 125 мл/л, едкого кали общего 65 г/л, едкого кали свободного 15 г/л и винной кислоты 50 г/л. . .A method of electroplating with a layer of bismuth in an alkaline electrolyte of products made of lead alloys or steel ovary products, characterized in that the process is carried out at a cathode current density of 0.5 a / dm and a temperature of 70-75 ° in the electrolyte of bismuth nitrate 75 g / l glycerin 125 ml / l, potassium hydroxide total 65 g / l, potassium hydroxide free 15 g / l and tartaric acid 50 g / l. . .
