Abstract:

Microarc oxidation coating and microarc oxidation-fluorocarbon coating were prepared on the surface of AZ80 magnesium alloy profiles. The phase structure, surface morphology and corrosion resistance of the coatings were investigated using SEM, XRD, copper sulfate spot test and polarization curve test. The main phase compositions of the microarc oxidation coatings were MgO, Mg2SiO4, MgSiO3, MgF2 and MgAl2O4. With increasing pulse voltage, the oxidation coating became thicker and the microstructure of the coating surface became compact; therefore the coating corrosion resistance was improved. Th

Abstract:

Today, binary, triple and quadruple zirconium alloys containing iron, chromium and copper are known for corrosion protection, which have a clear advantage over circal and niobium binary alloys in terms of corrosion resistance. However, insufficient attention is paid to studies aimed at studying the process of formation and morphology of oxide films on the zirconium alloy E110. This area of research has a high scientific and technical interest in the development of oxide coatings on metal surfaces, given the widespread use of zirconium alloys in nuclear energy as a structural material in the co

In the present study, SMAO discharge characteristics, coating morphology, and properties are analyzed and compared to results obtained from MAO under similar conditions.

Abstract:

A dense ceramic oxide coating approximately 30µm thick was prepared on a Ly12 Al alloy by microarc oxidation in an alkali-silicate electrolytic solution. The morphology and microstructure were analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD). Coating thickness and surface roughness (Ra) were measured after the coating had been synthesized. The tribological performance of the coatings was evaluated using a dry sand abrasion test and a solid particle erosion test. The results show that microarc oxidation coatings consist of the loose superficial layer and the inner dens

Abstract:

The microarc oxidation (MAO) coating and anodic oxidation coating were prepared on 5083 aluminum alloy. The surface morphology, elemental composition, and electrochemical behavior of the two coatings were analyzed. The results proved that the corrosion resistance of the MAO coating is superior than that of the anodic oxidation coating. The protective ability of the coating deteriorated gradually with the increase in immersion time. The corrosion process is controlled by ion diffusion throughout the coatings.

Abstract:

The growth of microarc oxidation (MAO) coatings on aluminum substrates was controlled by different mono-component solutions, involving (NaPO3)6, Na3PO4, Na2SiO3 and Na2MoO4 aqueous electrolyte. The results show that (NaPO3)6 solution can accelerate the growth of MAO coating, revealed by the maximum coating thickness of 12.1 μm; and meanwhile, Na2SiO3 solution favors the doping of solute elements during MAO, suggested by 10.75 at.% Si in coating. Furthermore, the variety of mono-component solution also affects the porous structure of MAO coating. It is assumed that the property of coating/solut
