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, formation water oil deposits, soil and pore water concrete. 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 certain period of exposure to aggressive media.
Using electrochemical DC methods, linear polarization in narrow and wide range of potential, cyclic polarization, cyclic voltammetry and chronoamperometry are implemented.
Nondestructive method of electrochemical impedance spectroscopy 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.
