analiza mikrostruktury - Opis:
- Surface pre-treatment is one of the most important steps before applying the final surface treatment. These pre-treatments, like phosphating, alkaline degreasing, pickling in acids, is used to remove impurities from the surface of the base material and to create appropriate conditions for adhesion of the final coating (metal coatings, organic coatings). Currently are on the rise surface treatments technologies, which are based on nanotechnology. It's a new generation of chemical products for the chemical surface preparation. This paper deals with the evaluation of microstructure of painted sheet metal after corrosion load with salt spray in the corrosion chamber. Metal sheets used for the experiment have been produced from low-carbon non alloy steel. For pre-treatment of the sheet metal was used alkaline degreasing (CC), iron phosphating (Feph) and nanotechnology based product Alfipas (Zr) in combinations: group A - CC + Zr, group B - Feph + Zr and group C - CC + Feph + Zr. The aim of this paper is to analyze the behavior of painted sheet metal after corrosion load and evaluate the effect of pretreatment to resistance of painted surface layer.
