Удаление активного покрыти с окисногр рутениево-титанрвого анода проводили в растворах, содержащих 2-20 г/л ионов фтора и 30-60 г/л сульфат-ионов. Опыты проводились при плотности тока 0,5-1,0 А/см, напр жении 25-50 В. Содержание окиси рутени в исходных образцах составило 1,6 мг/см.Removal of the active coating from the oxide-ruthenium-titanic anode was carried out in solutions containing 2-20 g / l of fluorine ions and 30-60 g / l of sulphate ions. The experiments were conducted at a current density of 0.5-1.0 A / cm, voltage 25-50 V. The content of ruthenium oxide in the initial samples was 1.6 mg / cm.

Результаты опытов по электрическому удалению активного покрыти с окисньк рутениево-титановых анодов приведены в таблице. 5 Лабораторные испытани показали, что предлагаемый способ удалени активного покрыти с окисных рутениево- титановых анодов позвол ет проводить процесс с высокой скоростью, сниматьThe results of the experiments on the electrical removal of the active coating from the oxide ruthenium – titanium anodes are given in the table. 5 Laboratory tests showed that the proposed method of removing the active coating from ruthenium – titanium oxide anodes allows the process to be carried out at a high rate, to remove
- 10 практически все покрытие, легко контролировать ход процесса и прекращать его после удалени всего активного сло с поверхности электрода. Кроме того, способ позвол ет достичь требу- 15 .емую микрошероховатость титановой . основы анода, что улучшает адгезионные свойства электрода и исключает дополнительные операции подготовки титановой основы перед нанесением 20 окисного рутениевого титанового покрыти .- 10 almost the entire coating, it is easy to control the process and stop it after removing the entire active layer from the electrode surface. In addition, the method allows to achieve the required titanium microroughness. anode base, which improves the adhesive properties of the electrode and eliminates additional steps of preparing the titanium base before applying the 20 ruthenium oxide titanium coating.
