Summary
Europe is one of the largest markets for fasteners and automotive sector in the world. About 4% of the gross national product of the EU is destroyed by corrosion. About 25% of this could be avoided by protecting the surface. Typically, pure zinc or zinc alloys are used as cathodic corrosion protection layers due to its sacrificial property. INHALE project will focus on the development of efficient, low toxicity and environmentally friendly halide-free ionic liquids as electrolytes for the electrodeposition of zinc and zinc alloys, used for corrosion resistant coatings applications and address the problem of reducing the material usage by employing light weight structures. The aspects investigated are the electrochemical behaviour of the metals ions, the coating properties (thickness, morphology, quality, corrosion resistance), the effect of the electrolyte conditions (pH, concentration, temperature, conductivity, viscosity ), electrolyte components (cations, anions, metal salts, water content) on the electrodeposition of zinc and zinc-based alloys (containing Ni, Co, Fe etc.). The conductivity of plating bath will be correlated with the current eciency, deposition rate and morphology of the coatings. Influence of the water content on the Ni, Co, Fe content, current eciency, surface morphology, phase structure and corrosion resistance of Zn alloy coating shall be investigated in detail. The effects of viscosity, conductivity and electrochemical window of the ionic liquids (ILs) will be studied in relation to the water content in ILs and nucleation, growth process of the electrodeposited Zn, Zn based alloys. Finally the performance and stability of the halide-free ionic liquid based electrolyte towards improving the plating efficiency shall be validated by carrying out the throughput studies of zinc-based coatings in a 25-30 L plating bath (prepared using the novel, halide-free ionic liquid) and compared with aqueous solution based system.
