Накратко на български

Металните повърхности се покриват със специални наноконтейнери, които могат да съдържат инхибитори срещу корозия или други защитни вещества. Това помага за по-бързо и евтино производство на устойчиви части за автомобилната индустрия.

MULTI-functional metallic SURFaces via active Layered Double Hydroxide treatments

The second half of MULTISURF project was dedicated to the investigation of mechanism of LDH formation on the surface of active metals as well as screening of different functionalities, which can be added together with active corrosion protection. Using synchrotron facilities (HZG outstation - DESY/Hamburg), it was shown, that anionic exchange in LDH nanocontainers happens much faster in comparison with expected previously. This result is significantly important for further TRL increase of the KDH formation and functionalization processes, since it leads to the reduction of time and respectively costs of the conversion treatment. In parallel to this work, the concept of dissolution modulators was developed for direct LDH growth on the surface of magnesium alloys as explained in overall project achievements. Within close collaboration between the partners of MUTISURF consortium, for a first time ZnAl LDH was synthesized directly on both pure zinc and zinc galvanized steel. The solubility of aluminum compound in electrolyte was found to be a critical issue for this synthesis. However, optimization of temperature, pH, time and other parameters let us perform this synthesis and load the formed LDH with corrosion inhibitors. This approach was further tested for corrosion protection and confirm its effectiveness. One can expect, that further optimization of the process parameters will let is possible the treatment of real automotive details against corrosion and effective LDH use for industrial application. In addition to active corrosion protection, LDH based nanocontainers were tested for providing antifouling, hydrophobic and sensing functionalities. It was shown and presented in the technical (confidential) part of the report, that this functionalities can be reached with LDH via anionic exchange. However, the TRL of these results is still low and additional work is required.

Цел на проекта

The main objective of the proposal is development of active multi-functional surfaces with high level of self-healing ability on the basis of Layered Double Hydroxide (LDH) structures formed on different industrially relevant metallic substrates. The main idea of the project is based on “smart” triggered release on demand for functional organic or inorganic anionic compounds intercalated into intergallery spaces of LDHs. The active functionality is achieved via controllable substrate-governed growth of LDH architectures on Al, Mg and Zn based alloys. The functional anions such as corrosion inhibitors, biocides, drugs, or hydrophobic agents are introduced into the intergallery spaces during the growth of LDH or upon a post-treatment stage. The release of the functional agents occurs only on demand when the respective functionality is triggered by the relevant external stimuli such as presence of anions or local pH change. The proposal focuses on two main applications, namely aeronautical and automotive. The active LDH treatments can bring significant benefits when applied in these situations. The respective relevant substrates are chosen as the main objects of interest: Mg alloys for both applications; Al alloys for both transportation industries as well; galvanized steel as a main material for automobiles. Moreover the suggested surface treatments, especially the one with active self-healing ability, are also considered for light-weight multi-material structures which are prone to fast galvanically-induced corrosion. The increase of the fault tolerance and reliability of hybrid designs is aimed in this case. The suggested surface treatments can offer possibility for fast implementation of the process at industrial level. The main expected impacts are related to the improvement of the life cycle of the light-weight structures utilized in transport industries via optimization of the maintenance schedules and increasing the fault tolerance.
