Composite deposition mechanism of 4,5-dichloro-2-n-octyl- 4-isothiazolin-3-one in zinc films for enhanced corrosion resistant properties

The present research seeks to address biologically influenced corrosion by electrodepositing a novel 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one(DCOIT)-zinc composite films for enhanced corrosion resistantproperties. Investigated by electrochemical methods, energy dispersive spectroscopy distributionmapping, and infrared absorption spectroscopy, a deposition mechanism was proposed wherein theDCOIT molecule chelated the zinc ion to participate in electrodeposition. The DCOIT-zinc chelateproduced obvious alterations in the surface morphology and crystal orientations. Thermogravimetricanalysis determined the DCOIT mass fraction in the composite film was 5%. The DCOIT-zinc compositefilm demonstrated uniform corrosion in natural seawater and the enhanced anticorrosion property wasachieved by successfully embedding DCOIT.
