چکیده انگلیسی
Since the loss of properties of organic coatings due to abrasion is of primary importance in the material performance, the reduction of barrier properties of organic coatings due to abrasion is studied by electrochemical impedance spectroscopy. The damage of organic coatings caused by abrasion impact of different abrasive materials and abrasion as a result of rubbing aggressive agents against the coating surface is analyzed by environmental scanning electron microscopy (ESEM). The falling abrasive test induces a decrease of coating thickness that can be detected by the thickness gauge and capacitance measurements and it is the main responsible of the loss of coating properties. On the other hand, Taber Abraser test creates scratches by which the protection properties are reduced.
