- چکیده:
- چکیده انگلیسی: Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve the
nanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueous
suspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,
composition, wear, and corrosion resistance of PEO coatings was investigated using Scanning
Electron Microscopy (SEM), elemental analysis with Energy Dispersive Spectroscopy (EDS), X-Ray
Diffraction (XRD), cyclic polarization test, and pin-on-disk wear test. The results showed that adding
nickel sulfate (NiSO4) and infiltration of its constituents into coatings lead to a more favored corrosion
behavior. Moreover, in the case of best sample, anodic current at the highest applied potential
condition during the cyclic polarization test indicated a drop within two decades. Moreover,
coefficient of friction decreased almost by half.- انتشار مقاله: 10-05-1394
