This study aimed to present the differences in corrosion properties and protective ability of two bi-layer systems obtained on low-carbon steel a model corrosive medium 5% NaCl solution. These newly developed consist Zn-Co (3 wt.%) or Zn-Ni (10 alloy coatings as under-layers very thin TiO2 sol-gel film top-layer. Scanning electron microscopy (SEM) is used for characterization surface morphology samples indicating that some quantitative appear result different composition both zinc alloys....
The presented manuscript demonstrates the effect of thickness a zinc alloy sublayer on corrosion resistance and stability three types bi-layer systems composed Co- or Ni-modified coatings (both as sublayers) top sol–gel ZrO2 film in 5% NaCl solution. In order to obtain more detailed information, sublayers were electrodeposited with different thicknesses (1, 5 10 µm, respectively) low-carbon steel substrate. Three consecutive dip-coated layers deposited thereafter individual sublayers. For...
Abstract In the present work, inhibiting effect of environmentally friendly cerium and phosphorus-based conversion films on zinc corrosion in 5% NaCl 1 N Na 2 SO 4 test media was investigated. The were prepared by immersion stirring passivating/converting solution for time periods 3,5,7, 10 min., respectively. chemical composition determined EDX analysis. results electrochemical studies showed that medium, cerium- exhibited high inhibition only during first days polarization resistance (Rp)...
The aim of the present investigation was to demonstrate a preparation method for obtaining an electrodeposited composite zinc coating with incorporated carbon nanotubes (CNT). coatings were additionally treated in newly developed conversion solution based on Cr(III)-containing compound. surface morphology Cr(III) and non-Cr(III) samples investigated scanning electron microscopy (SEM), metallographic structure X-ray diffraction analysis (XRD) composition photoelectron spectroscopy (XPS)....
Abstract The presented work reports on the peculiarities of anodic behavior, corrosion resistance and protective ability electrodeposited Zn-Ni-P alloys with a different composition in model medium 5% NaCl. Three characteristic coating types have been investigated using experimental methods such as potentiodynamic polarization (PD) technique (Rp) measurements. In addition, X-ray diffraction (XRD) analysis well scanning electron microscopy (SEM) coupled an Energy-dispersive (EDAX) device were...
Composite ternary zinc-based alloys Zn-Ni-P and Zn-Fe-P containing embedded multi-walled carbon nanotubes (CNT) were obtained electrochemically. They treated additionally in an environmentally friendly chemical conversion solution for passivation based on Cr3+-compound. The surface morphology, phase composition of the coatings after their treatment passivating determined by SEM, EDS XRD analysis respectively. corrosion behaviour composite alloy deposits both with or without additional film...
