Positive Effect

Представлены результаты ускоренных климатических испытаний композиционных полимерсодержащих покрытий на сплаве алюминия АМг3. Выявлено положительное влияние импрегнированного в поры ПЭО-покрытия композиционного материала на смачиваемость и коррозионную стойкость исследуемых образцов в условиях долговременного воздействия соляного тумана. Наиболее высокую коррозионную стойкость продемонстрировали образцы с четырехкратным нанесением ультрадисперсного политетрафторэтилена. The results of accelerated climatic tests of composite polymer-containing coatings on the AMg3 aluminum alloy are presented in the paper. According to the results of the studies carried out, a positive effect of the penetrated composite material into the pores of a PEO-coating on the wettability and corrosion resistance of the test samples under conditions of long-term exposure to salt fog has been revealed. The highest corrosion resistance was demonstrated by samples with a fourfold (СС-4x) application of superdispersed polytetrafluoroethylene.

The Impact

In this study, a novel metal matrix composite based on 60 vol% 316L stainless steel and 40 vol% MgO manufactured by powder metallurgy technology was developed. The corrosion resistance of the developed steel–MgO composite material against molten aluminum alloy AlSi7Mg0.3 was investigated by means of wettability tests and long-term crucible corrosion tests. The wettability tests were carried out using the sessile drop method with the capillary purification technique in a hot-stage microscope (HSM). Static corrosion tests were performed in molten aluminum alloy at 850 °C for 168 h to evaluate the impact of pre-oxidation of the composite surface on the corrosion resistance. The pre-oxidation of steel–MgO composites was carried out at 850 and 1000 °C for 24 h, based on preliminary investigations using thermogravimetry (TG) and dilatometry. The influence of the pre-oxidation on the composite structure, the corrosion resistance, and the phase formation at the interface between the steel–MgO composite and aluminum alloy was analyzed using SEM/EDS and XRD. The impact of the steel–MgO composite material on the composition of the aluminum alloy regarding the type, size, and quantity of the formed precipitations was investigated with the aid of ASPEX PSEM/AFA and SEM/EBSD. It was revealed that the pre-oxidation of the steel–MgO composite at 1000 °C induced the formation of stable MgO-FeO solid solutions on its surface, leading to a significant increase of long-term corrosion resistance against the liquid aluminum alloy.

5083 Aluminum Alloy

The microarc oxidation (MAO) coating and anodic oxidation coating were prepared on 5083 aluminum alloy. The surface morphology, elemental composition, and electrochemical behavior of the two coatings were analyzed. The results proved that the corrosion resistance of the MAO coating is superior than that of the anodic oxidation coating. The protective ability of the coating deteriorated gradually with the increase in immersion time. The corrosion process is controlled by ion diffusion throughout the coatings.
