The corrosion of PANI/SiO2 composite in synthetic geothermal atmosphere

  • An extraction of silica from natural sands of Bancar has been conducted by means of alkali fusion route using NaOH and mechanical alloying using planetary ball milling. The PANI/SiO2 Composite system has been coated in steel surfaces using spraying method. This study was designed to obtain PANI/SiO2 as an anti-corrosion coating material. The filler materials in the composite System consist of micro- and nano-SiO2. The structure of synthesized SiO2 be characterized using XRD and TEM. Corrosion of PANI/SiO2 composite has been tested using immersion method in synthetic geothermal atmosphere (Nord Deutsche Becken/NDB solution). The surface morphology after corrosion was observed by using SEM/EDX. XRD-Patterns and TEM show that the size of produced SiO2 is micro and nano. The size and composition of filler have influenced to surface degradation in geothermal atmosphere significantly. The addition of nano-SiO2 in the PANI matrix influenced corrosion resistance better than micro-SiO2 fillerAn extraction of silica from natural sands of Bancar has been conducted by means of alkali fusion route using NaOH and mechanical alloying using planetary ball milling.

The addition of nano-SiO2 in the PANI matrix influenced corrosion resistance better than micro-SiO2 filler qualitatively. The nano-SiO2 has a high potential as an anti-corrosion material in geothermal atmosphere. The product of corrosion is mainly Fe2O3 and the corrosion process is identified as a pitting corrosion.zeige mehrzeige weniger
