Application Prospects

Colorization for fabricating aluminum pigments has broad application prospects in recent years. In this study, yellow-colored aluminum pigments with the double-layer structure Al@SiO2@PFMV were prepared using a sol-gel method. A crosslinked copolymeric dye (PFMV) was firstly synthesized by radical polymerization using vinyl triethoxysilane (VTES) and a small molecular dye (FGMAC) as monomers. Then, colored aluminum pigments were prepared by hydrolysis and condensation of the copolymers on the surface of aluminum pigments. SEM, AFM, FTIR, and XPS were used to characterize the surface morphology and chemical structure of the colored aluminum pigments. It was found that the colored aluminum pigments have a heterogeneous and smooth surface layer. The anticorrosion results showed that the colored aluminum pigments had better chemical stability with significantly improving corrosion resistance compared to raw aluminum pigments and Al@SiO2 with the single-layer coating. Chromatism analysis indicated that the lightness of Al@SiO2@PFMV pigments decreased slightly and the color changed from silver-gray to yellow.

Layer Coating

The objective of the work was to select a suitable methodology for accelerated corrosion tests of single-layer coating compositions (hereinafter referred to as CC), to assess the condition of coatings during corrosion tests and to evaluate the resistance of the monitored single-layer CCs after the completion of the tests in selected corrosive environments. The results were used for the determination of the potential use of the selected single-layer coating compositions in agricultural environments. The following single-layer, water-based CCs were applied to sheet steel samples: V 2026, Aquapol_J and Denapox EZ. The following synthetic CCs were selected: AR 40-00, Krahokryl_J and ACS 20-ST. The resistance of these coatings was tested in 5 corrosive environments: in NaCl environment according to CSN EN ISO 7253, in SO2 environment according to CSN EN ISO 3231 and in the environment of a condensation chamber with de-ionized water according to CSN 03 8131. To simulate agricultural environments, solutions of the Cererit fertilizer and pig semi-liquid manure were selected. The samples were left in the condensation chamber in aqueous environment according to CSN 03 8131 for 8 hours and then soaked in Cererit or semi-liquid manure and left in the laboratory environment for 16 hours. Samples were evaluated according to CSN EN ISO 4628-1, 2, 3. The water-based CC Denapox EZ and the synthetic CC AR 40-00 reached the best results.

Chemical and electrochemical techniques were applied to evaluate the porosity of various electroless coatings (single-layer coating, multilayer coating and ternary coating). The electrochemical techniques include linear polarization resistance and Tafel extrapolation method. The effects of these techniques were compared. It’s evident that electrochemical methods performed better than chemical method when they were applied to assess the porosities of coatings with very fine through pores.
