A method of testing for the behavior of hydrogen in a metal probe as well as measuring apparatus for carrying out the test method

摘要

The present invention relates to a method and apparatus for determination of the water material behavior in a metal probe (6). Via the water material behavior of a statement can be made over certain properties of the metal probe (6), for example, capable of enamel, make. The behavior of hydrogen is determined in the metal probe (6) of the fact that by way of at least one on one side of the metal probe (6) proton-conducting solid electrolyte (5) is arranged an ac voltage is applied, wherein the metal probe (6) including the solid electrolyte (5) is subjected to a hydrogen-containing atmosphere. In case of a change of the frequency of the alternating voltage is obtained for a specific frequency, the smallest phase angle between the applied voltage and the current which flows through the metal probe. This frequency is a parameter for the determination of the transit time of the hydrogen through the metal probe (6).
