Theory

Part I: Corrosion & corrosion costs: relevance to materials’ & infrastructure durability, economy & society, corrosion impact Corrosion types – classification and overview Chemical corrosion – oxide layers, growth, protective ability. 

Part II: Corrosion mechanisms (general, localized, galvanic corrosion) General and localized corrosion, forms and environment General corrosion vs localized corrosion   Galvanic corrosion Microbiologically-induced steel corrosion.

Part III Electrochemical corrosion – electrochemical terminology - Electrochemical & electrolytic cells Electrochemical thermodynamics and kinetics Passivity and stability of passive films

Part IV: Protection against corrosion - Galvanic coatings and layers - Hot-dip Zn coatings – Electrodeposition - Organic coatings and liners (overview) Cathodic protection (impressed current and sacrificial)

Part V: Corrosion and protection in reinforced concrete Cement-based microstructure and micromechanics related to steel corrosion and steel/cement paste interfaces Corrosion and impressed current cathodic protection evaluation: synergy of electrochemical methods and cement-based material science (microstructure of cement-based materials)

Hands-on practical sessions

  • electrochemical methods for corrosion assessment (lab) – metals in aggressive medium: electrochemical response & corrosion current densities (corrosion rates);
  • new: evaluation of corrosion products on metals prior to & after corrosion tests – qualification via electron microscopy (ESEM) and surface analysis (EDS) ;
  • corrosion tests in reinforced concrete – corrosion state of steel reinforcement in reinforced mortar & concrete; new: electron microscopy steel/cement interface;
  • corrosion protection (lab and field) – demonstration of impressed current cathodic protection - application & efficiency evaluation;
  • synergy of electrochemistry and concrete material science – correlation of results on corrosion rates of steel and microscopy of steel/cement paste interface; cement-based bulk matrix electrical properties – links with electrochemical techniques (EIS).
