Sažetak
Exposure to environment yields corrosion of metals, while to corrodent will increase the rate. Thereof, the development of protective coatings has been continuous industrial demand. With plethora of various mono-functional coatings, the concerns have been raised regarding their environmental acceptability, and stability. With recently developed smart coatings that bring about concepts like self-healing, and selective/multi-activity, concerns repose on difficulties to achieve complex architectures or functional groups in simple, cheap and easy-to-scale-up manner. Yet, recent activities show it is possible to exhibit multi-functionality without abovementioned discrepancies. Thereof, this investigation utilises cheap-wet-chemistry to from simple nano-architectures by “smart assembly” with functionalities comparable to those of “smart materials”. First of all, we withhold from one-pot synthesis and thereof, with the help of hydrolysis-rate-control-agents, sol-stabilisers, drying-control-agents and post-processing, the distinction of properties was maximised in each layer. Sol-gel method was utilised to tailor different (porosity or high specific surface control) but homogeneous and compatible layers that can be assembled into multifunctional composites. First, metal-contacted protection-layer was dense, crystalline, thin, i.e. barrier from both from environment and chemicals, with low porosity and SS surface, closed pores and excellent mechanical properties. Second layer was thicker, amorphous, container-type with additives, open mezzo-pores and reasonable mechanical properties. Various agents can be infiltrated. Third layer was based on core-shell particles partially penetrating/closing the pores of the 2nd layer thus blocking the infiltrated additives and partially forming additional top layer. Overall, the submicron multi-layer-coating was processed below 350°C to show crack-free, anti-corrosive and tribo-efficiency with good mechanical properties.
