Microstructure and Performance of Mechanically Plated Zn-Ti Composite Coating
Published 2021-01-01“…In order to obtain mechanical plating with better corrosion resistance, zinc powder and titanium powder were mixed in a mass ratio of 15∶11 to make the Zn-Ti composite coating on the surface of the steel body by mechanical plating.Ammonium bifluoride was used as the activator of titanium powder particles; stannous sulfate guided the deposition and acted as the filling material on the connection between zinc powder particles and titanium powder particles; EDTA, urotropine and OP-10 were used for chelating deposition to form a plating layer.Metallographic microscope(OM), scanning electron microscope(SEM)were used to analyze the morphology and microstructure of the coating.Scribing the coating to check whether the coating was warped or peeled.Electrochemical method and neutral salt spray test were used to detect the electrochemical performance and corrosion status of the coating.Results showed that the Zn-Ti composite coating had complete coverage, the surface was rough.The coating firmly adhered to the substrate well.The particles in the coating combined well.Zinc powder and titanium powder were inlaid and stacked.Metal tin mainly connected between the coating and the substrate and among the particles.The self-corrosion potential Em of the composite coating was-1 096 mV, and that of the zinc coating was-1 240 mV.The polarization resistance of the composite coating was 7.07 Ω·cm2, and that of the galvanized layer was 5.11 Ω·cm2.In the salt spray test of 720 h, the red rust area of the composite coating was about 15% of the zinc coating.The metal particles of the coating were mechanically bonded.The metal tin boundary was clearly observed between the coating and the substrate and among the metal particles.There was no alloy transition of the coating, and the dense plating particles were conducive to the improvement of corrosion resistance.In the salt spray experiment, the composite coating had less white rust and red rust than the zinc coating, and intact and compact white rust can slow substrate corrosion.…”
