Testing of corrosion in our laboratory is mainly done by exposure testing and/or by electrochemical tests (cyclic polarization measurements). Exposure tests are closest to reality and therefore yield the most accurate corrosion rates. However, exposure tests require longer test times as compared to electrochemical tests. Moreover electrochemical tests yield additional information with regard to e.g. the risk for pitting corrosion, passivation behaviour etc.

Typical issues for which corrosion tests can be performed:

  • Material selection
  • Testing of corrosion inhibitors
  • Existing reactor is used in a new application
  • Estimate effects of changes in the process on corrosion

METALogic also offers several corrosion tests for the testing of coatings. Please click here for more information with regard to coating tests.

Exposure tests

Exposure testing is typically performed for purposes of material selection, quality control, CLP-directive, …. In an exposure test a coupon (test plate) of the material to be examined (metal, coated metal, [...]

Materials selection

Based on our specific knowledge and many years of experience in corrosion studies, corrosion testing and failure analyses METALogic can assist you in selecting the most appropriate material for your [...]

Cyclic polarization tests

In the laboratories of METALogic cyclic polarization measurements are performed to study the behaviour of metals under different exposure conditions: measuring a corrosion rate, resistance to pitting [...]

Indirect corrosion analyses

Beside direct testing of corrosion by means of exposure tests or electrochemical tests information with regard to the corrosion process or corrosion risk can be obtained in an indirect way. Some of the [...]
