Abstract

Изобретение относится к электрохимической защите металлов от коррозии и касается метода определения потенциала незаряженной поверхности металла (φε), а также способа защиты, основанного на установлении защитного потенциала, равным φε. Устройство (фиг. 5), реализующее способ такой защиты, включает устройство для определения φε, в котором напряжение от источника переменного тока (13) подается на вспомогательный электрод (3) и на мост переменного тока, который формирует прямой и обратный импульсы напряжения, подаваемые на исследуемый электрод (4). Величина φεопределяется с помощью электронного осциллографа (9). Защита реализуется подачей тока защиты от источника постоянного тока (17), при этом с помощью резистора (16) или регулятора тока (18) устанавливается значение защитного потенциала, равное φε. Определение с высокой точностью и использование φεповышает эффективность защиты металла.The invention relates to the electrochemical protection of metals against corrosion and relates to a method for determining the potential of an uncharged metal surface (φε), as well as a method of protection based on the establishment of a protective potential equal to φε. The device (Fig. 5) that implements the method of such protection includes a device for determining φε, in which the voltage from the AC source (13) is applied to the auxiliary electrode (3) and to the AC bridge, which generates forward and reverse voltage pulses supplied on the studied electrode (4). The value of φε is determined using an electronic oscilloscope (9). Protection is implemented by applying protection current from a DC source (17), while using a resistor (16) or a current controller (18), the protective potential value is set to φε. Definition with high accuracy and the use of φε increases the effectiveness of metal protection.
