Sažetak
With plethora of various cheap mono-functional anti-corrosive coatings, the questions have been raised regarding their feasibility. Smart coatings recently bring up self-healing, selective- and multi-activity. Yet, they usually utilise complex nanostructural architectures or chemical functionalisation, which is rarely cost-effective. This investigation tries to utilise the cheap wet-chemistry synthesis to from a simple nano-coating. Homogeneous layers of materials, which separately show only average properties, are assembled in multifunctional composites, with the aim to match the level of functionality of the “smart materials”, yet advantageous in price, scale-up possibility, etc. In contrast to often reported, this concept reposes on dense layer adjecent to substrate to act as a physical barrier. The ordered bonds in dense layer could yield the upgrade of the mechanical properties so the goal is to make it crystalline. The dense layer may not perfectly cover the substrate due to its high surface roughness (also thermal expansion coefficient mismatch), where the second layer is of key importance. Subsequent layer should be tailored to have open-pore porous microstructure but also to remain with reasonable mechanical properties. The pores should serve as a container for infiltration of agent, for example of a standard anticorrosive liquid. Tailoring of the corrosive protection depend on infiltrated agent, while additional functionality can be ensured by adding further layers.
