Электролит для электрохимического полирования изделий из титана и его сплавов относится к электрохимической обработке металлов и может быть использован для полирования деталей сложной конфигурации, например корпусов искусственных клапанов сердца. Для повышения срока службы электролита он содержит, мас. %: азотную кислоту 7 - 16, плавиковую кислоту 27 - 30, четвертичную аммонийную соль на основе 5-трифторметил-3,6-диоксаперфтороктан сульфонилфторида, диметилпропан диамина и этиленхлоргидрина 0,03 - 0,5, а также серную кислоту, составляющую дополнительную до 100% часть. Достигаемый эффект: при оптимальном технологическом режиме (анодная плотность тока 80 - 100 А/дм2, напряжение 8 - 15 В, температура 20 - 60°С, время обработки 30 - 60 с) обладает сроком службы, равным 180 - 200 А ч/л.Electrolyte for electrochemical polishing of products made of titanium and its alloys refers to the electrochemical machining of metals and can be used to polish parts of complex configuration, for example, the cases of artificial heart valves. To increase the service life of the electrolyte it contains, wt. %: nitric acid 7 - 16, hydrofluoric acid 27 - 30, quaternary ammonium salt based on 5-trifluoromethyl-3,6-dioxperfluorooctane sulfonyl fluoride, dimethylpropane diamine and ethylene chlorohydrin 0.03 - 0.5, and sulfuric acid, which is an additional 100% part. Achieved effect: at the optimum technological mode (anode current density of 80–100 A / dm 2 , voltage 8–15 V, temperature 20–60 ° C, processing time 30–60 s) has a service life of 180–200 A h / l
