| titleOfInvention | Process and equipment for the determitation of the inclination of intercrystal corrosion of corrosion-proofaustnitic chrome-nickel steels |
| abstract | The method and apparatus of the present invention allow the testing of materials that are prone to crystalline corrosion by means of electrolytic polarization. During the process, the test substance was contacted with an electrolyte as an electrode, then a voltage range was set to ensure the passive state of the entire test surface and the passive current was measured after the equilibrium was reached. The voltage is then changed in the negative direction until the entire surface is reactivated and the current of the active state is measured after a suitable time. In contrast to the methods proposed so far, the essential advantage of our method is that it is not necessary to add the full polarization curve, but it is sufficient to measure the current density in some correctly selected, preferably active and passive states, and compare them with each other, and the relationship between the values can be inferred from the inter-crystalline steel. its corrosion resistance. The apparatus comprises an electrolytic cell to which the material to be tested is connected as an electrode and in which the platinum electrode and the reference electrode are located. Figure 1 |
