| Popis: | In this work, acrylic coatings were deposited on sandblasted soda-lime glass in order to correct the loss of optical properties. Erosion tests were carried out under normal incidence with a constant sand flow 25 m/s. By varying the projected sand mass, different surface states were obtained. The influence of the roughness on the optical properties and the mechanical behavior of the coating was observed. At the erosion beginning, eroded samples show isolated defects randomly distributed on the surfaces. As the projected sand mass increases, the number and the size of defects increase. Consequently, the optical transmission drops dramatically from 91.4% (initial value) to 20% after sandblasting with a mass of 200 g, while the arithmetic roughness increases from 0.04 to 2 μm. To correct the damage caused by sandblasting, a 10 μm thick acrylic coating was deposited by spraying. The resultant polymeric coating reduces the surface roughness and improves significantly the optical transmission (90%) which is close to the initial value. Scratch tests were carried out using an increasing normal load to study the adhesion behavior of acrylic coatings deposited on the sandblasted glasses. The results show that the roughness has an influence on the value of the critical load of delamination at the interface coating/substrate. Therefore, the coatings resistance is related to the surface roughness state. The effect of HF-etching of sandblasted glasses on the interfacial adhesion of acrylic-coated glasses was also investigated. |
