Apparatus for measuring the degree of sensitization of metal articles |
摘要 |
An apparatus for measuring the degree of sensitization of metal articles comprises an electrochemical cell in which the potential of a test-piece of the article with respect to a reference electrode is made to vary linearly with time by feeding currents of suitable intensity from the passivation field to the activation field by means of the counter-electrode; a pair of electrodes moves along the test-piece surface with the respective electrode ends kept equidistant and disposed along an axis substantially perpendicular to the test-piece surface, one of them being in contact with said surface; by measuring the potential difference of this pair of electrodes as a function of their position, the local degree of sensitization of the test-piece is obtained.
