Abstract
Organic coatings are the most commonly used system for protection from corrosion of a metallic product. The required properties of paints include protection from corrosion phenomena, resistance to abrasion and good aesthetic aspect. This is particularly important for the automotive and transport industry, building trade, domestic products, and packaging. The aim of this work is to investigate the effect of wet abrasion and erosion on the protective and aesthetic properties of an organic coating system. Falling abrasive test and Taber test were chosen to produce the mechanical damage, using different abrasive slurries in order to evaluate the influence of the viscosity of the liquid mean and the hardness and shape of the abrasive agents. The level of aesthetic damage was evaluated through gloss measurements; 20° was the most sensitive angle to gloss changes; with this geometry, samples with different damage level could be compared. The correlation between the changes of gloss and the damage was investigated using optical microscopy and environmental scanning electron microscopy. The level of loss of protective properties was evaluated through electrochemical impedance spectroscopy measurements.
