防腐疏水等离子喷涂静态接触角阻抗谱Anticorrosion Resistance Hydrophobic Plasma Spraying Technology Static Contact Angle Im-pedance Spectroscopy



Purpose of this paper was to prepare Al2O3-TiO2 coating on Q235 substrate that has good hydro-phobic nature and outstanding corrosion resistance. The Al2O3-TiO2 coating with Ni-Fe intermediate layer were prepared on Q235 alloy surface using plasma spraying technology, and then the  coating is characterized by using SEM (scanning electron microscope), contact angle measurement, salt fog corrosion chamber and electro chemical work station to measure the surface morphology, contact angle corrosion resistance and impedance spectroscopy of coating. Coating prepared by plasma spraying and dipping in the aqueous solutions of dodecanoic acid(ASD) for processing can make the static contact angle increase to 129˚, the change in surface morphology for ASD is not obvious after immersing in the nature sea water and storing in salt fog conditions. This indicated good corrosion resistance of the ASD coating.
