W Katedrze Technologii Zabezpieczeń Przeciwkorozyjnych realizowane są różnorodne badania naukowe z zakresu korozji, ochrony przed korozją, inżynierii materiałowej i elektrochemii. Rozwijane są cyfrowe pomiary impedancyjne procesów elektrodowych, pomiary składowych harmonicznych oraz szumu elektrochemicznego. Rozwijane są metody badań impedancyjnych prowadzone w warunkach nieustalonych. W tym celu stosowane są metody łączne czasowo-częstotliwościowej analizy. Poza metodami elektrochemicznymi rozwijana jest technika nanowagi piezoelektrochemicznej, elipsometrii i emisji akustycznej. W katedrze projektuje się i bada nowe materiały elektrodowe oraz powłoki kompozytowe.

In the department there are carried out different scientific researches in the field of corrosion, anticorrosion protection, materials engineering and electrochemistry. Digital measurements of electrode processes impedance, harmonic components and electrochemical noise are developed. These investigations are conducted in non-stationary conditions. For this purpose join time-frequency analysis methods are applied. Parallel to electrochemical methods the techniques of piezoelectrochemical nanobalance, elipsommetry and acoustic emission are developed too. New electrode materials and composite coatings are designed and examined in the department.
