Laboratory for Corrosion and Protection of Metals

Lab activity

The basic purpose of this laboratory is the study of corrosion of various types of metals and their protection under conditions that simulate realistic ones. These conditions are as follows: maritime conditions, oil deposits’ formation water, soil and concrete pore water. The methods used are non-electrochemical and electrochemical, DC and AC methods.
Non-electrochemical corrosion tests include gravimetric method for the determination of the metal corrosion rate, which is based on the measurement of the sample mass before and after a cer-tain period of exposure to aggressive media.
Using electrochemical DC methods, linear polarization in narrow and wide range of potential, cyclic polarization, cyclic voltamme- try and chronoamperometry are implemented.
Nondestructive method of electrochemical impedance spectros-copy is used for the testing of boundary phase metal-electrolyte. In order to test the corrosion of metals in the soil, soil pH, redox potential of the soil and the soil resistance are examined.

PROJECTS

  • Natural Organic Corrosion Inhibitors

SERVICES

  • During the burial of metal structures in the soil, it is important to investigation is the soil corrosivity. In assessing the soil corrosivity we can determine (in the field and the laboratory) the minimum soil resistance as well as soil pH level in accordance with the standards AASHTO 288 and AASHTO 289.
