  7. 5. The role of particles on initial atmospheric corrosion of copper and zinc : lateral distribution, secondary spreading and CO2-/SO2-influence

    Författare :Zhuo Yuan Chen; Christofer Leygraf; Jan-Erik Svensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; copper; zinc; NaCl particles; NH4 2SO4; Materials chemistry; Materialkemi;

    Sammanfattning : The role of sodium chloride (NaCl) particles and ammonium sulfate ((NH4)2SO4) particles on the initial atmospheric corrosion of copper and zinc was investigated under in situ and ex situ conditions using microgravimetry, FTIR spectroscopy, ion chromatography, scanning electron microscopy with x-ray microanalysis and the scanning Kelvin probe. For the first time, in situ infrared spectra were collected on a micron level during particle induced atmospheric corrosion using a recently developed experimental set-up for in situ FTIR microspectroscopy.
