Description
Изобретение относитс к короэйонньом исследование м,а именно к способам измерени скорости коррозии токопровод щих материалов.The invention relates to a corona research, in particular to methods for measuring the corrosion rate of conductive materials.
По основному авт. св. № 724991 известен способ определени скорости коррозии токопровод щих материалов, заключающийс в том, что через испытуемые образцы,параллельно включенные в электрическую цепь,параллельно друг другу размещенные на рассто нии ,, равном от одного до п ти значений полусуммы линейных размеров сечений, определ емых в направлении пр мой, соедин ющей их геометрические центры, пропускают ток звуковой или ультразвуковой частоты, измер ют сопротивление образцов и по нему суд т о скорости коррозии 1.According to the main author. St. No. 724991, a method for determining the corrosion rate of conductive materials is known, which consists in: through the test samples, connected in parallel to an electrical circuit, parallel to each other, spaced from one to five times the half-sum of the linear dimensions of sections, the direction of the direct geometrical centers connecting them passes a current of sonic or ultrasonic frequency, measures the resistance of the samples and judges the corrosion rate 1.
Недостатком известного способа вл етс его невысока точность, так как не учитываетс вли ние на процесс р да параметров, нап.ример температуры.The disadvantage of this method is its low accuracy, since it does not take into account the effect on the process of a number of parameters, such as temperature.
Цель изобретени - повышение точности измерений.The purpose of the invention is to improve the measurement accuracy.
Указанна цель достигаетс тем, что нанос т неэлектропроводное коррозионностойкое покрытие на всю поверхность одного из образцов и наThis goal is achieved by applying a non-conductive corrosion-resistant coating to the entire surface of one of the samples and to
поверхности остальных образцов, обращение к изолированному образцу, а сопротивление образцов измер ют при периодическом изменении направлени тока .в изолированном образце.the surface of the remaining samples, the reference to the isolated sample, and the resistance of the samples is measured by periodically changing the direction of the current in the isolated sample.
На чертеже приведена электрическа схема устройства дл реализации способа .The drawing shows the electrical circuit of the device for implementing the method.
Устройство содержит генератор 1 The device contains a generator 1
10 переменного тока, коммутатор 2, мостовую схему, в плечи- которой включены компенсационный образец 3, испытуемый образец 4, б.алластное сопротивление 5 и регулировочное соп15 ротивление 6. На определенном рассто нии от испытуемого образца 4 размещ н изолированный образец 7, площадь поверхности которого больше или равна площади поверхности испытуемо20 го образца 4. Образец 7 через коммутатор 2 подключен к генератору 1 Переменного тдка. Устройство содер .жит также усилитель 8, детектор 9 и регистратор 10.10 alternating current, switch 2, bridge circuit, shoulders of which include compensation sample 3, test sample 4, lost resistance 5 and adjustment resistance 6. At a certain distance from test sample 4 there is an isolated sample 7, surface area which is greater than or equal to the surface area of the test sample 4. Sample 7 through switch 2 is connected to the generator 1 Variable tdka. The device also contains an amplifier 8, a detector 9 and a recorder 10.
