Abstract
The final surface properties of aluminum flat products vary depending on different processing conditions such as changes in alloy elements, different annealing temperatures, rolling parameters and surface chemicals used in the degreasing process. These changes in process parameters affects the surface roughness, surface oxide formation and structure. Thus, the next process steps such as surface pre-treatment, painting, bonding etc. are determining factors for the surface quality in processes. In this study, 1xxx and 3xxx series of aluminum alloys were examined. Different annealing temperatures between 220 and 480 °C were applied to cold rolled aluminum sheets , surface roughness and wetability (adhesion behaviour) values were examined. In addition, the effects of acidic and alkaline surface chemicals on the surface adhesion with different degreasing qualities, have been investigated depending on the degreasing parameters (immersion time, bath temperature, chemical concentration). Surface qualities were measured using different test methods such as; roughness measurement, wettability, cross cut test, cupping test, impact test and cylindrical bend test to understand physical and tribological properties of base material.
